I stripped the speaker wires and connected them to there corresponding wires on the rca. I also took out the amp from the factory sub enclosure. And completely hidden the amp assembly. Love the setup!! Working perfectly. I also used a SmartThings smart plug to turn off the sub when it’s not receiving signal from the amp when the soundbar is turned off.
@samyech889, it depends on the space. It may do well in smaller spaces but struggle in bigger spaces like an open concept house. There's no way my Samsung sub could achieve 20% of the bass the 12" Klipsch is outputting now after the modification.
When I look at this, this is exactly what I did to my connection, I am using a Sony ht 350, now I managed to connect 3 subwoofers on that cable and it is working very well and so powerful though 💪
Hey my friend I have the 990c and I’m reverting my living room back to just a surround sound and soundbar setup because I had a full home theater system setup but had my receiver die on my so I decided I didn’t want to complicate things anymore and just wanted to go with the 990c. But I still wanted to use my 12” Klipsch, and this works like a charm!! I also disconnected the factory sub and just use the 12”. Sound is perfect and I can also control the sub level with the app
hi @deshawnmiller21, you mean you tap directly from the circuit board output (while the samsung subwoofer module speaker is been disconnected). also your 12” klipsch connected through high level input?
I currently have the q600c and I’m having the same issue for movies its good but I want more bass for music and watching your video I think I’ll do the same🔥
😂😂😂 There is always some asshole in the comments hating. You haven’t done this yourself but make assumptions like you know what his results are. Sheesh.
@@christiank.8035 pretty much, but i soldered the wires to the speaker terminal. Also drilled a hole in the box and adding a 3.5mm female so i can easily unplug it
It should be fine. I've been using it for over a month without any issues whatsoever. And I've done same for my other soundbar without any issues, too. I don't foresee any problems.
I’m currently waiting for my HW-Q990C. I think I’ll take it to my electronics repair guy and get him to tap off the non-amplified signal side instead of the amplified signal side and use my SVS subwoofer. 👌🏻
@@humix100 I don’t think I’m going to bother. The HW-Q990C with my Samsung Q90 series 65 inch TV with Q-Symphony is more than loud enough for a bedroom. I’m actually quite impressed, and I competed in dBDrag Car Audio stuff for years. If it was my main system, maybe, but no need. I mean even my Center Channel can handle 600wRMS of power 😂
I got my 990D last week and I absolutely agree- the sub is okay for movies but it's monotonous garbage for music. I have a couple of Dream Acoustics 12" subs that I'll be doing this to. Will just remove the board from the samsung sub entirely.
I have this working on my Klipsch R-12SW…It really does require a line level converter to convert from speaker wire taps on the Samsung to RCA in on the sub…I tried it both ways, with and without the converter…Without the converter the bass is bloated and muddy and I have to keep the gain below 1…With the converter the bass is clean, not bloated or muddy and I can increase the gain to 2-3…It makes sense to me that this solution would require a converter to get accurate bass reproduction.
Hey, thanks for sharing. I am in the process of doing the same thing. However, my powered sub is a high input (1000 watts), and since many have said that a LOC is not required for a high input sub, I am torn between surpassing the LOC or still using one. Please suggest. Thanks a ton in advance.
@nh-tech, thanks. I dodged the LOC and wired directly to the powered sub. Unlike yours, the gain on the sub seems very versatile; I can turn it all the way up without it sounding muddy or boomy. It's fantastic. I hope nothing goes wrong with either amp.
Great work on expanding the availablility of additional bass. The only issue I see here is if there is any processing from the amp used to tune the frequency response of the original sub. The cross over on the Klipsch can help but I wonder if this will affect the bass response of the added sub.
You should have used a subwoofer with high level inputs...that's the better way to go...you will eventually fry the amp in the Samsung wireless subwoofer...The SVS pro series has high level inputs...that's what I'm using.

For the rear side speakers, ceiling speakers and subwoofer, at first thought, I was thinking their powerful will be reduce by half or more because they have been tap and share watts with each other. But after listening to those speakers, they sound very powerful too. It is very amazing. Why they are still sound so powerful? Isn’t it is like for example the USB power adapter stated 20 watts and has two changing port, if we charge one phone, it has the full 20 watts charge, but when we add another phone to charge, it is divide by half and provide 2 x 10 watts for both phones, isn’t it this way?
Your theory is correct. Some amps would struggle to adequately power parallel speakers due to the lower impedance, but not the amps in the Q990C. But the lower impedance lowers distortion and is usually louder, except the speakers can be a bit more power-hungry.
Super dude I already have Klipsch R110SW and I am buying Samsung Q990C but wasn't happy with the bass ,May God bless you .I am going to connect it hope nothing otherwise happens to either of the subs
@@hunterjones9209because the two signals are aren’t the same and your changing the load on the amp. Either use a speaker to line level converter that also has the correct ‘ load’ for the Samsung amp, or remove the Samsung amp and put it in the better sub.
Dude. You really inspired me!! I’ve now ordered all the wires and wire splicing kit to add a second subwoofer and extra speakers!! 🎉. I’m kinda worried about the extra speakers over heating the factory Amps. But first I’m gonna add the second subwoofer via high level inputs!!! I’m looking at a couple 12” subs with high level inputs but I just got an email from svs about their new “sound path speaker level adaptor”!!!!! 🎉🎉. I really think you should get one and add it to your system to compensate for the high level inputs!!! 🎉🎉
Have you gotten this working?.. I bought the SVS sound Path adapter, I connected the speaker wire to the adapter (right side only) and connected the single Rca out of the adapter into the input on the sub.. Tried both LFE and right input on the sub and all i get is a slight hum and just barely any bass output. Wondering where I went wrong.
Nevermind.. it was my fault. I apparently moved one of the wires from the speaker terminals when I moved the Samsung sub into position. I made sure both negative and positive were reconnected and held it in with electrical tape and connected the speaker wire to the SVS adapter and from there a blue jeans shielded RCA cable to LFE and it almost works too well with Klipsch R-112SW.
Hi. Thanks for the great idea. I have the same sound bar but did the installation a bit diferent than what you did here. I used the same subwoffer imput from inside the samsung sub and plugged in a wire(speaker wire + ,-) from the samsung sub to my Klipsch SW350 subwoofer high line imput on the back. You can use only one Channel since they are both conected on the inside. This way you dont mess with the impedance or overheat the samsung subwoofer amp since the newly added Klipsch sub wont add or substract anything from its original load. Iine will only be used as a high level signal. Btw paid 30$ for the sub used on FB Marketplace and it turbed this soundbar into a Beast. Turned the bass all the way down to 40hz And the gain is at 1/4 volume. Anything more and it will rattle the windows next to the wall and or overpower the whole thing.
Good suggestion. The reason I didn't use the converter is because I used the LFE input on the sub. Usually, a sub will treat the RCA connection as a full range stereo source. Since the signal coming to the Samsung sub is already filtered by the soundbar and is not full range stereo, then it wasn't necessary to convert it to low-level input.
You have done this incorrectly as many others have said, as you are going from hi level out to low level/ rca in…I just did this with my Samsung 990C sub last night but just ran speaker wire from the +/- on the Samsung woofer to the hi level inputs on a paradigm powered sub. You need to get a hi to low level converter or a sub with hi/ speaker level inputs to do this correctly.
this is amazing! your channel is great.... Do you know Classy, B the installer, FOMO (from Stop the FOMO), Caleb, Andrew & Kristi, and Brians tech therapy (I see things) lol. Are you guys like all good friends? I really like the mod, to be honest I wasn't sure it would work. I don't think it's a good idea as the wires are hanging out of the sub, my kids would rip that a part lol. It sounded very bass heavy, perhaps you just had the bass level extra high so we could all hear it. When bass is set correctly, you won't hear it, the bass should blend into the music/movie.
Thanks! I've seen their videos, but I don't know any of them personally yet. About the sub, I keep the Klipsch sub very low for everyday listening experience.
Wow, good job !!! Is it also possible with Samsung Q800T Soundbar?? If yes, Could anyone recommend some cheaper subwoofer than klipsch? Pls give me some cheaper models that will work. Thank You Very Much!!!!
Please allow my one question, to make sure I understand everything correctly. The Samsung system is 656 W. The Subwoofer you chose has 200W continues and 400W Peak. One would think that this is working because the power specs of the Sub is less than the Samsung system. BUT, is it true that in theory the Sub could be ANYTHING, as in 3000 Watts continous and 4000 Watts Peak because it has ITS OWN amplifier and gets its power from the Wall anyways, Right? The "tap" as you call it, is ONLY to receive the Low Frequency INFORMATION from the Samsung Subwoofer and nothing power related. Right? Thanks in advance. I was thinking on adding a 14inch Sub.
That's right! The sub has its own amplifier and only receives sound signal from the Samsung system. As long as your sub is powered, you should be fine.
The LF info IS power, the more you turn it up, you drive speaker level power into the line level input, plus you have the sound of the crappy Samsung sub as well as the better sub. Just get one decent sub, like any pro installation.
@@dbefore7165 Would this be less of a concern adding a line level converter between the subwoofer output, and new powered sub input? I get it's a hack and not ideal, but for me personally my only complaint with this system is the weak subwoofer. The soundbar and surrounds are good enough (for now) for the price and minimalist aesthetic. I'm trying to avoid having to buy a dedicated LCR setup if I can help it.
Is it possible to just disconnect the original samsung woofer en solder the samsung amp cables to the new sunwoofer? If thats possible, whats the best way to wire it? Thank you
You can do that, but the sound will not be good enough if you intend to power the New sub with just the Samsung subwoofer amp. The Samsung sub amp is not powerful enough to drive my 12-inch sub. You can, however, connect the Samsung amp cables to a high to low-level input converter, and connect RCA from the converter to your sub.
I feel like the people who complain about the bass of this soundbar are looking for either overpowering bass or don’t have the smart things soo and aren’t able to use all the features of the bar, like enhancing the bass and turning up the woofer. Or they are using it in a space that’s just too large, but then the entire soundbar would be struggling to fill that space….
Thanks for your comment, Alex. The bass suffers in large areas, especially those of us who use it in open concept homes. I would turn up the bass to +6, use bass boost in the app, changed location to a corner, and it was still lacking in music play. It was okay for movies, though!
1 subwoofer is a huge problem because you need 2 for smooth even bass yes you'll get more output but you can dial down the output on both subs he could of been sitting in a null where the sub was placed and by adding a second one could get rid of the null in that spot then you over driver the samsung sub because of the null and then the mids get all muddy up
@@Sc2God724most hi end home theatres and studios only need one sub, why’s that? And explain how two subs will even the phase and freq response in relations to room nodes and standing waves.
If I'm not mistaken, the factory data is for a 200w rms subwoofer. I think this would fill even a huge villa room. For example, it can make the couch vibrate while watching a movie. What was the difference with the method you used? By the way, I think the subwoofer cabinet was designed incorrectly.
@@rafars2246 I think the subwoofer box in the Samsung q990d model is designed incorrectly. Let's change the subwoofer unit so that the subwoofer and air outlet ports face us by taking the box in the svs pb16 ultra model as a reference, then we will get better quality bass sounds. For example, if the factory system vibrates the seat 7 units when a bomb explodes, this will reach 10 units after the cabinet change. The factory product has a wrong design with a subwoofer facing the side and an air port facing the wall from the back. In addition, since the box volume is small, it cannot create enough volume. In other words, there is no need to buy an additional subwoofer. Just change the box. I am in favor of the q990d being sufficient even in halls up to 100 m². Those who want more professional sound and cinema quality can create systems like real 5+1, 7+1, 7.1.2, 7.1.4 7.1.6. Those who prefer bass can buy 2 subwoofers, and the choice is up to them. But if I were to take myself as a reference, I have a 40 m² living room. The sound of the q990d is sufficient. I think it will be sufficient even if I move to a larger house in the future. But I always dream of professional systems.
@@hakansalihoglu I have no idea about design, but I will say the Samsung subwoofer is just plain small and it tries too hard to sound big. Terrible performance. I am buying another subwoofer for my q990c.
Thanks for the video! Exactly what I was looking for. Just a question... I'm going to buy the following model (R-12SWI) comes with 2.4Ghz wireless hi-fi pre-paired transmitter. Do you know if can I add the transmitter to the back of my Samsung Subwoofer connecting the wires out of the speaker to the transmitter? So I can get that wireless signal to a Klipsch Subwoofer?
Ok, I’m coming back after my first test with the setup and I just want to say woow! As an audiophile person is what I looking for! Thanks for your recommendation!
im confused.. you're tapping the powered line at the Samsung speaker but using it as the line in on the powered sub? isnt that supposed to be line level input not speaker level? thanks
Yeah, that's correct. It should be line level, but the only way to get that would be to open up the soundbar and tap the line that goes to the wireless transmitter. That's the easiest way to let most people destroy their system. Hence, this adaptation, which works great.
@@nh-tech’tapping’ the line won’t help, your still send hi level signal to the line level input of the new sub, best convert the signal to feed new sub
I was thinking... can you try to use your creativity and see if there is any way to add a second pair of rear speaker? :) I mean, wouldnt it be great to have 4 rear ones, 2 placed to the side and 2 placed behind the listener? I know those are wireless? Would there be a way to "Tap" into those wireless signals their to another set of wireless speakers or even maybe use speaker cables after a "tap" to the second pair of speakers using cables? Im just thinking out loud... if anyone can do it its you 😊
Thanks for your kind words. Yes, that's something I can definitely explore. The Samsung rear speakers are already great, with three drivers each. Given that you're interested in a side firing speaker, then tapping into just the side driver would be best. It can easily be done with speaker wires. I'll explore all other possibilities and let you know.
@@nh-tech Thanks man... that would be amazing.. I ordered my Q990C during Black Friday week and actually your video tipped me over... right now I have to wait 10-12 more days until I get mine so in excitement my mind has wandered :) maybe because Im also a Bass-Head and love my bass both for Hiphop/RnB but also for Blockbuster movies... and one 8 inch sub just cant cut it... now thanks to you... that is fully solved. But when it comes to surround, no matter what Samsung says... this system is a 5.1.2... speaker placement determines that... now if we can place the included speakers as Rear ones but "Tap" into the Side channel of them to place direct firing side speaker either with speaker cables a set of actual (not reflected) side speakers or with their own wireless Samsung SWA-9500S maybe? .. that would LEGIT make the system 7.1.2... or with all your tricks 7.2.2 :) let me find a video that might help you as you understand electronics ect...hold up
Maybe something like the old Polk S10 satellite speakers, I think only need 20W to be driven and can be found cheap used ect... or the newer Polk ES10 is like 190 USD on Amazon right now... could be perfect for something like this... they are even ATMOS/DtsX rated :) OR maybe eeeven "smarter" would be to use 2 speakers off the old Logitech Z906, they for sure are low Watt driven, I would guess far less than the Samsung surrounds... Im just shooting ideas to spark your creativity... I dont see anyone else thinking outside the box AND make it work like you so I hope IF its possible you can make it happen :)
Hi buddy, I love that you shared your mod with the community and explaind the process step by step ❤ I recently ordered 990c, and since I’m waiting for my 990c to be dispatched, watched a lot of reviews and videos and bumped on yours. I have zero knowledge with electronics, so I have two questions - if you could do something differently about the mod (let’s say money are not an issue), what would you change (except getting different speaker set LOL)?, what subwoofer model would you get, and why, and how would you connect it? Another question - can you just plug Klipsh directly to the soundbar, so basically replace samsungs inferior sub? Wouldn’t that be easier/better? Cheers!
Starting from your last question, yes, you can do that but you'll need to remove the amp module together with the wireless module from the Samsung sub and connect it directly to the speaker in the new sub. Given that my setup is working perfectly, I probably wouldn't change anything. Lol. The Klipsch is good, but I would probably get the SVS pro series with better quality, wider frequency range, and better controls.
Hi mate, been watching your videos and think there fantastic!! I’ve just brought the 990c and totally agree with you! Do you think I can buy the same sub that comes with the 990c unit and run them both? Would you recommend a slightly cheaper sub if not? Thanks
Thank you! I think you need a bigger sub than the q990c unit. Nothing less than 10 inches would be better. You can get a cheaper 10" active sub, and you'll get a better bass.
@@nh-techthank you for the fast response! Do you have any recommendations around the £250/300 mark? Thanks to be honest it’s for my bedroom so 10ish will be more then enough.
@@dbefore7165 dude, you can't move a larger speaker with an amp designed to move an 8" speaker. Where in hell did you got your degree? I have no clue, but this is so basic...
You can, and it's almost the same thing I did, except I used the output in the sub and maintained the connection to the Samsung speaker for flexibility.
@@nh-techhave you tried it? i mean the samsung sub amp worked just fine w/o the subwoofer driver not connected and the circuit board output directly to the rca or high level input? i worry about the no-load (no speaker) connected to the samsung circuit board output.
@12pseudonym have you tried it already? output of the samsung circuit board directly connected to the rca or high level input of any other sub? im thinking about doing this also.
Bro u did what i was imagining. But i was too scared to do so. Just wanted to know after this sub mod any issues. 3 months now u are using. I want to connect as u did 2nd subwoofer to my q990c. 2nd sub i have is 6 ohms will there be any issue.
There's been no issues so far. Everything is working great. If the new sub has an in-built amp, then it should work fine, but if it's passive, then you're better off using the Samsung amp to drive only the new sub.
@@nh-tech have you made any new videos on this subject yet? I would love to know more about using the Klipsch wireless transmitter inside the Samsung SW. My understanding is I would cut the RCA plug off and attach the two wires to the speaker terminals inside the Samsung SW, and that's it.
Nice, but should you not use a subwoofer using speaker output into a line level input. Best to buy a subwoofer with speaker level inputs. You are driving the subwoofer with high power going into the speaker feeding the Klipsch. Klipsch line level relies on low signal input to trigger the amp. You will blow the Kipsch. Best to get a speaker to line level converter. Just from what I remember when I use to fiddle with car stereos.
Yes and no. The Samsung amp is feeding the speaker; let us say 4 ohms. Depending on how the amp is designed, it may not be able to handle the higher/lower olms of adding another speaker (depending if you were to wire it in series or paraelle) into the chain. Though wiring in series + to - is USUALLY safe it will double the olms, y ou will have less amp ouput. Also the speakers will be out of phase (which maybe a good thing for bass) so have to be careful about bass cancellation so subwoofer placement will be more critical. @@sedrickransom6904
Has someone tried this with a proper sub that goes down under 20hz ? Is the signal getting filtered like 25hz cut for these high port tune subs from dsp ?
@@nh-tech Hi Do you know about the audio control LC2i line output converter? If you do is it important to have that converter in order to protect the wireless sub amp.
You're going to destroy the Klipsch sub with the amplified level you're feeding it. You need something to convert that signal to line level before you can feed it into those RCA inputs on the sub. The reason your gain is all the way down is because you're overdriving on the input side.
Hello there! I am trying to do something similar, following the advice of some engineer friends. I bought a LOC Kicker KISLOC 2-Channel K-Series. However, I can see there are six wires with L and R channel(stereo), and I'm stuck on which ones to join/connect with the Samsung driver since it has only two connectors (positive and negative). Should I just use one channel as a mono and leave the rest unused? Please advice
@@Epikfl0 Eventually, I dodged the high to low level converter(LOC) because it turned out my powered sub was high-level input that can handle up to 1000 watts. So what I did was directly hook up speaker(16 gauge copper) wire to my new powered sub from the soundbar sub driver inside the cabinet, just like the video showed. My soundbar sounds like full stereo set up. It sounds fantastic, be it music or movies. If your new sub is high-level input, I suggest you leave the LOC. Ensure good speaker wire or good quality RCA is used.
@@AS-sc2jn Hey thanks for the reply. I ended up just doing a T-splice into the existing wires leading up to the terminals but good to know another way. That sounds more reversible if needed, hopefully I won't need to make any changes.
@@christiank.8035 Already closed everything back up but at 4:40 in the video there's a plug with red and black wires. Those lead to the Samsung speaker. I disconnected that plug, pulled back the foam covering on the wires and got a length of 16/2 speaker cable. Did T-splices (google it) to both wires, soldered the splices, and then covered with liquid electrical tape. Put the Samsung back together and ran the other end of the speaker wire out of the subwoofer port as shown in the video, and then to the Right speaker-level inputs on my secondary sub.
@NH-Tech Thanks SO much! I've been wanting to do this since I received my Q990C system last summer. A quick question. I have no need (or space) for 2 subwoofers. Would this hack work if I simply put the Samsung subwoofer's control board in a ventilated box (something like a mini ATX tower) and just disconnected it from its original woofer altogether?
Hello, thank you for your how-to video. I managed to configure it to work but the bass does sound boomy and muddy. I bought everything specified in your description and was wondering if someone can explain a fix for that
I suggest you reduce the bass level in the app or woofer level on your Samsung remote. I usually set it below zero. Also, check if the sub volume isn't too high. I have it less than a quarter of the sub volume. Hope that helps.
@@nh-tech Thank you for your reply. I will try following your advice, hope it helps. Another thing that happens is that when the soundbar goes offline, the subwoofer will go crazy, booming. Is there a fix for that as well?
@@nh-tech Thanks for your response once again. I do not have another sound system to test it on so my fix is to always turn it off when it starts booming
i really want to go down this route as i am very disappointed with the bass coming from the q990c sub. should i get the klipsch r121 and a line level converter or should i get the svs pb1000 pro?
@hunterjones9209 There is always some unassumed risk. Based on my hypothesis and experience, the risk of damage to the Samsung sub is almost nonexistent as long as the wiretapping is done well (not leaving naked wires), and the external sub is active (powered). The tap is a parallel connection, so resistance is low. I have tested my theory with another soundbar (Sony), and it is also working perfectly.
I'm a little confused, it looks like you're connecting the Klipcsch rca wire to an already amplified signal - at the Samsung's Driver? @@nh-tech Would this cause issues for Klipsch's amp? Cheers
It could be a problem if the amplified signal was only going to the Klipsch. But because the Samsung speaker is drawing power from the amplified signal, it weakens the power going to the Klipsch.
I would also like to connect my second xtz 12 Inc subwoofer but it doesn't have lfe input but only stereo RCA how can I do it thanks and sorry for my school English.
You can use an RCA splitter 1 female to 2 male. You can check this out amzn.to/419EgG7. You could also use a high to low-level converter. Hope that helps!

This mod is wrong on ever level, please get a basic grasp of electronics and just swap the amp module from the Samsung with the new sub, that’s how it’s done
Hi, Mr. Electronics Expert - the amp in the Samsung sub is rated 26W and you want me to use that to power a 400W driver? In another comment, you said to replace it with a new sub: from where? Do you realize you cannot just wirelessly pair another subwoofer to another soundbar? You again said that soundbars are not for large spaces: does that mean you shouldn't own a soundbar if you live in an open-concept floor plan? Better still, have you seen the Nakamichi shockwafe and Drangon? How about Sonos Arc, which allows for additional sub? I appreciate your concern, but what you know is not the only way. The basis for knowledge is so that you can think outside the box, when necessary.
@dbefore7165 If my working results in the video could not convince you, why would I waste my time giving you my credentials? Do you need my resume before accepting that my method works perfectly?
@@nh-techwrong wrong wrong. Electronics obeys laws of physics that you seem oblivious to. These soundbars work by wall reflections, if the rooms large then the tiny drivers struggle to work properly for pretend surround. I’ve said my qualifications, what’s yours?
I stripped the speaker wires and connected them to there corresponding wires on the rca. I also took out the amp from the factory sub enclosure. And completely hidden the amp assembly. Love the setup!! Working perfectly. I also used a SmartThings smart plug to turn off the sub when it’s not receiving signal from the amp when the soundbar is turned off.

Awesome work. I think lots of Samsung fans wish their soundbars came with bigger subs

Very good base already
@samyech889, it depends on the space. It may do well in smaller spaces but struggle in bigger spaces like an open concept house. There's no way my Samsung sub could achieve 20% of the bass the 12" Klipsch is outputting now after the modification.
That's adventurous! My advice is to use active (powered) speakers as the soundbar may not have enough power for passives.
Just buy a bigger sub

Hey buddy did you added this subwoofer in your new q990c if yes then is it fine to do that?
Yes, I added it to my new soundbar. As long as you don't mind voiding your warranty, it should be fine
I don’t care about warranty i just want to know if it is good in long run like would be there any issues in future after couple months?
It should be fine. I've been using it for over a month without any issues whatsoever. And I've done same for my other soundbar without any issues, too. I don't foresee any problems.
I'm sure there is a way to tap the line out prior to the amp. it's probably connected between the wifi/bluetooth to the amp connection.
I’m currently waiting for my HW-Q990C. I think I’ll take it to my electronics repair guy and get him to tap off the non-amplified signal side instead of the amplified signal side and use my SVS subwoofer. 👌🏻
Did you manage to use the SVS? I have a svs sb-1000 for few years now and I want to use it with HW-Q990C.
@@humix100 I don’t think I’m going to bother. The HW-Q990C with my Samsung Q90 series 65 inch TV with Q-Symphony is more than loud enough for a bedroom. I’m actually quite impressed, and I competed in dBDrag Car Audio stuff for years. If it was my main system, maybe, but no need. I mean even my Center Channel can handle 600wRMS of power 😂
Don't you need a speaker level input for the new subwoofer since there is no LFE output from the samsung sub?
I got my 990D last week and I absolutely agree- the sub is okay for movies but it's monotonous garbage for music. I have a couple of Dream Acoustics 12" subs that I'll be doing this to. Will just remove the board from the samsung sub entirely.
I have this working on my Klipsch R-12SW…It really does require a line level converter to convert from speaker wire taps on the Samsung to RCA in on the sub…I tried it both ways, with and without the converter…Without the converter the bass is bloated and muddy and I have to keep the gain below 1…With the converter the bass is clean, not bloated or muddy and I can increase the gain to 2-3…It makes sense to me that this solution would require a converter to get accurate bass reproduction.
Hi, nice feedback, thanks you.
Which converter did you use for this ?
@@Bocoptor Scosche LOC2SL
Hey, thanks for sharing. I am in the process of doing the same thing. However, my powered sub is a high input (1000 watts), and since many have said that a LOC is not required for a high input sub, I am torn between surpassing the LOC or still using one. Please suggest. Thanks a ton in advance.
You don't need the LOC for your sub, unless you intend to use the low input on the sub instead
@nh-tech, thanks. I dodged the LOC and wired directly to the powered sub. Unlike yours, the gain on the sub seems very versatile; I can turn it all the way up without it sounding muddy or boomy. It's fantastic. I hope nothing goes wrong with either amp.
This is pretty awesome so all u need is a rca cable and you hooked wires to Samsung woofer terminals and thats it more bass from the q990d
Great work on expanding the availablility of additional bass. The only issue I see here is if there is any processing from the amp used to tune the frequency response of the original sub. The cross over on the Klipsch can help but I wonder if this will affect the bass response of the added sub.
Yeah, I'm wondering how it will effect Adaptive mode.
You should have used a subwoofer with high level inputs...that's the better way to go...you will eventually fry the amp in the Samsung wireless subwoofer...The SVS pro series has high level inputs...that's what I'm using.

how do i connect from the samsung sub to high level input?
For the rear side speakers, ceiling speakers and subwoofer, at first thought, I was thinking their powerful will be reduce by half or more because they have been tap and share watts with each other. But after listening to those speakers, they sound very powerful too. It is very amazing. Why they are still sound so powerful? Isn’t it is like for example the USB power adapter stated 20 watts and has two changing port, if we charge one phone, it has the full 20 watts charge, but when we add another phone to charge, it is divide by half and provide 2 x 10 watts for both phones, isn’t it this way?
Your theory is correct. Some amps would struggle to adequately power parallel speakers due to the lower impedance, but not the amps in the Q990C. But the lower impedance lowers distortion and is usually louder, except the speakers can be a bit more power-hungry.
@@nh-techsounds like you’ve finally read up on impedance, but the tiny Samsung amps will struggle as they can’t dissipate the heat and are cheap
Super dude I already have Klipsch R110SW and I am buying Samsung Q990C but wasn't happy with the bass ,May God bless you .I am going to connect it hope nothing otherwise happens to either of the subs
I haven't had any issues so far. Both subs are working perfectly. All the best! 🙏

Do not do it
@@dbefore7165 why is it bad?
@hunterjones9209 I think he's just trying everything possible to discredit my mod. lol
@@hunterjones9209because the two signals are aren’t the same and your changing the load on the amp. Either use a speaker to line level converter that also has the correct ‘ load’ for the Samsung amp, or remove the Samsung amp and put it in the better sub.
Nice work. Could you disconnect the Samsung subwoofer entirely and just use the Klipsch? Maybe make a 3D printed enclosure?
Yes, you can disconnect the Samsung sub by removing the wire that connects the board to the speaker, but I don't think it's necessary.
Dude. You really inspired me!! I’ve now ordered all the wires and wire splicing kit to add a second subwoofer and extra speakers!! 🎉. I’m kinda worried about the extra speakers over heating the factory Amps. But first I’m gonna add the second subwoofer via high level inputs!!!
I’m looking at a couple 12” subs with high level inputs but I just got an email from svs about their new “sound path speaker level adaptor”!!!!! 🎉🎉.
I really think you should get one and add it to your system to compensate for the high level inputs!!! 🎉🎉
thinking of going this route as well.. I hope you let us know if it worked out.
any update on this?
@christiank.8035 I ordered the svs sound path speaker adapter and it comes in Friday.. I'll reply again after this weekend after I give it a try
Have you gotten this working?.. I bought the SVS sound Path adapter, I connected the speaker wire to the adapter (right side only) and connected the single Rca out of the adapter into the input on the sub.. Tried both LFE and right input on the sub and all i get is a slight hum and just barely any bass output. Wondering where I went wrong.
Nevermind.. it was my fault. I apparently moved one of the wires from the speaker terminals when I moved the Samsung sub into position. I made sure both negative and positive were reconnected and held it in with electrical tape and connected the speaker wire to the SVS adapter and from there a blue jeans shielded RCA cable to LFE and it almost works too well with Klipsch R-112SW.
thanks you so much
Does the Room Correction still work w/ new sub?
It should, the Samsung sub has nothing to do with any room correction.
@@rafars2246 From what i've heard most of the Room EQ is for the bass frequencies
Hi. Thanks for the great idea.
I have the same sound bar but did the installation a bit diferent than what you did here.
I used the same subwoffer imput from inside the samsung sub and plugged in a wire(speaker wire + ,-) from the samsung sub to my Klipsch SW350 subwoofer high line imput on the back.
You can use only one Channel since they are both conected on the inside.
This way you dont mess with the impedance or overheat the samsung subwoofer amp since the newly added Klipsch sub wont add or substract anything from its original load.
Iine will only be used as a high level signal.
Btw paid 30$ for the sub used on FB Marketplace and it turbed this soundbar into a Beast.
Turned the bass all the way down to 40hz
And the gain is at 1/4 volume.
Anything more and it will rattle the windows next to the wall and or overpower the whole thing.
do you have a picture of this?
I have seen info that Samsung is coming out with a new sound bar early next years.
Does it improve movie performance or just music?
It improves everything by a huge margin
It is great modification but i think you need high level to low level audio converter
You can do that if you have high level input in subwoofer
Good suggestion. The reason I didn't use the converter is because I used the LFE input on the sub. Usually, a sub will treat the RCA connection as a full range stereo source. Since the signal coming to the Samsung sub is already filtered by the soundbar and is not full range stereo, then it wasn't necessary to convert it to low-level input.
@@nh-technot true
@@dbefore7165explain
You have done this incorrectly as many others have said, as you are going from hi level out to low level/ rca in…I just did this with my Samsung 990C sub last night but just ran speaker wire from the +/- on the Samsung woofer to the hi level inputs on a paradigm powered sub. You need to get a hi to low level converter or a sub with hi/ speaker level inputs to do this correctly.
@@dbefore7165you’re right, frequency range has nothing to do with hi/ low level in/ out, it’s basically pre out voltage.
this is amazing! your channel is great.... Do you know Classy, B the installer, FOMO (from Stop the FOMO), Caleb, Andrew & Kristi, and Brians tech therapy (I see things) lol. Are you guys like all good friends? I really like the mod, to be honest I wasn't sure it would work. I don't think it's a good idea as the wires are hanging out of the sub, my kids would rip that a part lol. It sounded very bass heavy, perhaps you just had the bass level extra high so we could all hear it. When bass is set correctly, you won't hear it, the bass should blend into the music/movie.
Thanks! I've seen their videos, but I don't know any of them personally yet.
About the sub, I keep the Klipsch sub very low for everyday listening experience.
Wow, good job !!! Is it also possible with Samsung Q800T Soundbar?? If yes, Could anyone recommend some cheaper subwoofer than klipsch? Pls give me some cheaper models that will work. Thank You Very Much!!!!
Any Ideas, some models please, thank you ?
Samsung b650 is amazing for movies and music for only $499
Please allow my one question, to make sure I understand everything correctly. The Samsung system is 656 W. The Subwoofer you chose has 200W continues and 400W Peak. One would think that this is working because the power specs of the Sub is less than the Samsung system. BUT, is it true that in theory the Sub could be ANYTHING, as in 3000 Watts continous and 4000 Watts Peak because it has ITS OWN amplifier and gets its power from the Wall anyways, Right? The "tap" as you call it, is ONLY to receive the Low Frequency INFORMATION from the Samsung Subwoofer and nothing power related. Right? Thanks in advance. I was thinking on adding a 14inch Sub.
That's right! The sub has its own amplifier and only receives sound signal from the Samsung system. As long as your sub is powered, you should be fine.
@@nh-tech thank you so much for your reply and for sharing your knowledge man ! Very cool of you! Have a good one!
The LF info IS power, the more you turn it up, you drive speaker level power into the line level input, plus you have the sound of the crappy Samsung sub as well as the better sub. Just get one decent sub, like any pro installation.
@@dbefore7165 Would this be less of a concern adding a line level converter between the subwoofer output, and new powered sub input? I get it's a hack and not ideal, but for me personally my only complaint with this system is the weak subwoofer. The soundbar and surrounds are good enough (for now) for the price and minimalist aesthetic. I'm trying to avoid having to buy a dedicated LCR setup if I can help it.
Wow....awesome job.
Thank you!
Is it possible to just disconnect the original samsung woofer en solder the samsung amp cables to the new sunwoofer? If thats possible, whats the best way to wire it? Thank you
You can do that, but the sound will not be good enough if you intend to power the New sub with just the Samsung subwoofer amp. The Samsung sub amp is not powerful enough to drive my 12-inch sub. You can, however, connect the Samsung amp cables to a high to low-level input converter, and connect RCA from the converter to your sub.
Thanks,
Im a bass lover and Samsung is not good on it but with this add you just fucking make it happens....
The Samsungs fine, it’s designed to playback cinema reference audio, not bass boosted music. Buy a big stereo with some bass bins
just fill with polyfill it will make the difference for deeper bass
I feel like the people who complain about the bass of this soundbar are looking for either overpowering bass or don’t have the smart things soo and aren’t able to use all the features of the bar, like enhancing the bass and turning up the woofer. Or they are using it in a space that’s just too large, but then the entire soundbar would be struggling to fill that space….
Thanks for your comment, Alex. The bass suffers in large areas, especially those of us who use it in open concept homes. I would turn up the bass to +6, use bass boost in the app, changed location to a corner, and it was still lacking in music play. It was okay for movies, though!
@@nh-techsound bars aren’t made for large areas, separates are
1 subwoofer is a huge problem because you need 2 for smooth even bass yes you'll get more output but you can dial down the output on both subs he could of been sitting in a null where the sub was placed and by adding a second one could get rid of the null in that spot then you over driver the samsung sub because of the null and then the mids get all muddy up

If I'm not mistaken, the factory data is for a 200w rms subwoofer. I think this would fill even a huge villa room. For example, it can make the couch vibrate while watching a movie. What was the difference with the method you used? By the way, I think the subwoofer cabinet was designed incorrectly.
Which cabinet?
@@rafars2246 I didn't understand what you wrote
@@hakansalihoglu you said "I think the subwoofer cabinet was designed incorrectly."
You didn't stated which cabinet is designed incorrectly.
@@rafars2246 I think the subwoofer box in the Samsung q990d model is designed incorrectly. Let's change the subwoofer unit so that the subwoofer and air outlet ports face us by taking the box in the svs pb16 ultra model as a reference, then we will get better quality bass sounds. For example, if the factory system vibrates the seat 7 units when a bomb explodes, this will reach 10 units after the cabinet change. The factory product has a wrong design with a subwoofer facing the side and an air port facing the wall from the back. In addition, since the box volume is small, it cannot create enough volume. In other words, there is no need to buy an additional subwoofer. Just change the box. I am in favor of the q990d being sufficient even in halls up to 100 m². Those who want more professional sound and cinema quality can create systems like real 5+1, 7+1, 7.1.2, 7.1.4 7.1.6. Those who prefer bass can buy 2 subwoofers, and the choice is up to them. But if I were to take myself as a reference, I have a 40 m² living room. The sound of the q990d is sufficient. I think it will be sufficient even if I move to a larger house in the future. But I always dream of professional systems.
@@hakansalihoglu I have no idea about design, but I will say the Samsung subwoofer is just plain small and it tries too hard to sound big. Terrible performance. I am buying another subwoofer for my q990c.
Thanks for the video! Exactly what I was looking for. Just a question... I'm going to buy the following model (R-12SWI) comes with 2.4Ghz wireless hi-fi pre-paired transmitter. Do you know if can I add the transmitter to the back of my Samsung Subwoofer connecting the wires out of the speaker to the transmitter? So I can get that wireless signal to a Klipsch Subwoofer?
Yes, the transmitter should work with the connection from the Samsung sub.

im confused.. you're tapping the powered line at the Samsung speaker but using it as the line in on the powered sub? isnt that supposed to be line level input not speaker level? thanks
Yeah, that's correct. It should be line level, but the only way to get that would be to open up the soundbar and tap the line that goes to the wireless transmitter. That's the easiest way to let most people destroy their system. Hence, this adaptation, which works great.
@@nh-tech’tapping’ the line won’t help, your still send hi level signal to the line level input of the new sub, best convert the signal to feed new sub

That’s the correct way, bigger isn’t always better, quality is what matters
Hi! will this way damage the samsung subwoofer? or the subwoofer you will add?
I have not had any problems with any of the subwoofers so far
I was thinking... can you try to use your creativity and see if there is any way to add a second pair of rear speaker? :) I mean, wouldnt it be great to have 4 rear ones, 2 placed to the side and 2 placed behind the listener? I know those are wireless? Would there be a way to "Tap" into those wireless signals their to another set of wireless speakers or even maybe use speaker cables after a "tap" to the second pair of speakers using cables? Im just thinking out loud... if anyone can do it its you 😊
Thanks for your kind words. Yes, that's something I can definitely explore. The Samsung rear speakers are already great, with three drivers each. Given that you're interested in a side firing speaker, then tapping into just the side driver would be best. It can easily be done with speaker wires. I'll explore all other possibilities and let you know.
@@nh-tech Thanks man... that would be amazing.. I ordered my Q990C during Black Friday week and actually your video tipped me over... right now I have to wait 10-12 more days until I get mine so in excitement my mind has wandered :) maybe because Im also a Bass-Head and love my bass both for Hiphop/RnB but also for Blockbuster movies... and one 8 inch sub just cant cut it... now thanks to you... that is fully solved. But when it comes to surround, no matter what Samsung says... this system is a 5.1.2... speaker placement determines that... now if we can place the included speakers as Rear ones but "Tap" into the Side channel of them to place direct firing side speaker either with speaker cables a set of actual (not reflected) side speakers or with their own wireless Samsung SWA-9500S maybe? .. that would LEGIT make the system 7.1.2... or with all your tricks 7.2.2 :) let me find a video that might help you as you understand electronics ect...hold up
Maybe from 02:35 is hopefully useful to you 🙏 ua-cam.com/video/RgS3iAs6rCs/v-deo.html
Maybe something like the old Polk S10 satellite speakers, I think only need 20W to be driven and can be found cheap used ect... or the newer Polk ES10 is like 190 USD on Amazon right now... could be perfect for something like this... they are even ATMOS/DtsX rated :) OR maybe eeeven "smarter" would be to use 2 speakers off the old Logitech Z906, they for sure are low Watt driven, I would guess far less than the Samsung surrounds... Im just shooting ideas to spark your creativity... I dont see anyone else thinking outside the box AND make it work like you so I hope IF its possible you can make it happen :)

Hi buddy, I love that you shared your mod with the community and explaind the process step by step ❤
I recently ordered 990c, and since I’m waiting for my 990c to be dispatched, watched a lot of reviews and videos and bumped on yours.
I have zero knowledge with electronics, so I have two questions - if you could do something differently about the mod (let’s say money are not an issue), what would you change (except getting different speaker set LOL)?, what subwoofer model would you get, and why, and how would you connect it?
Another question - can you just plug Klipsh directly to the soundbar, so basically replace samsungs inferior sub? Wouldn’t that be easier/better? Cheers!
Starting from your last question, yes, you can do that but you'll need to remove the amp module together with the wireless module from the Samsung sub and connect it directly to the speaker in the new sub.
Given that my setup is working perfectly, I probably wouldn't change anything. Lol. The Klipsch is good, but I would probably get the SVS pro series with better quality, wider frequency range, and better controls.

Every Subwoofer. Its simply taking a Signal to another Subwoofer. But also you should know, Not every Subwoofer will Sound well.
Yes, most active Subs should work although I can't guarantee how good they'll sound
Regarding movies is Samsung sub by itself powerful or still the another subwoofer?
The Samsung sub will do fine with movies. If you like explosive bass scenes, then getting a new sub will be better.
Nice, but should you not use a subwoofer using speaker output into a line level input. Best to buy a subwoofer with speaker level inputs. You are driving the subwoofer with high power going into the speaker feeding the Klipsch. Klipsch line level relies on low signal input to trigger the amp. You will blow the Kipsch. Best to get a speaker to line level converter. Just from what I remember when I use to fiddle with car stereos.
So if the Klipsch sub has a High Level Input, everything should be fine?
Yes and no. The Samsung amp is feeding the speaker; let us say 4 ohms. Depending on how the amp is designed, it may not be able to handle the higher/lower olms of adding another speaker (depending if you were to wire it in series or paraelle) into the chain. Though wiring in series + to - is USUALLY safe it will double the olms, y ou will have less amp ouput. Also the speakers will be out of phase (which maybe a good thing for bass) so have to be careful about bass cancellation so subwoofer placement will be more critical. @@sedrickransom6904
Ok. Thanks!

Hi
Do you know about the audio control LC2i line output converter? If you do is it important to have that converter in order to protect the wireless sub amp.
You're going to destroy the Klipsch sub with the amplified level you're feeding it. You need something to convert that signal to line level before you can feed it into those RCA inputs on the sub. The reason your gain is all the way down is because you're overdriving on the input side.
Hello there! I am trying to do something similar, following the advice of some engineer friends. I bought a LOC Kicker KISLOC 2-Channel K-Series. However, I can see there are six wires with L and R channel(stereo), and I'm stuck on which ones to join/connect with the Samsung driver since it has only two connectors (positive and negative). Should I just use one channel as a mono and leave the rest unused? Please advice
Yes, just use one channel as a mono
@@MattZim101Howd your mod go? I am thinking of going the same route with the same high to low level converter.
@@Epikfl0 Eventually, I dodged the high to low level converter(LOC) because it turned out my powered sub was high-level input that can handle up to 1000 watts. So what I did was directly hook up speaker(16 gauge copper) wire to my new powered sub from the soundbar sub driver inside the cabinet, just like the video showed. My soundbar sounds like full stereo set up. It sounds fantastic, be it music or movies. If your new sub is high-level input, I suggest you leave the LOC. Ensure good speaker wire or good quality RCA is used.

That sounds like there may be a problem with your sub. Does it do that when you use it with a different system, or only with the Q990C?
@@nh-tech Thanks for your response once again. I do not have another sound system to test it on so my fix is to always turn it off when it starts booming
I would recommend getting a replacement sub if it's still under warranty. It seems there's an internal defect.
i really want to go down this route as i am very disappointed with the bass coming from the q990c sub. should i get the klipsch r121 and a line level converter or should i get the svs pb1000 pro?
Both routes would be good, but I’ll recommend the svs pb1000
@@nh-tech I've done it today
@tahirhussain9743 did it work out okay?
@nh-tech Will this work with Klipsch Reference Premiere RP-1400SW 14"?
Sure. That's a great sub you have there. It should work without problems
So does this mean that the original 990C sub and the klipsch sub both work together? I’m not familiar with tapping.
Yes, both of them are working together, although the Klipsch puts out about 80% of the bass.
@@nh-techAnd is it safe to do? Is there a chance that it’ll damage the samsung sub?
@hunterjones9209 There is always some unassumed risk. Based on my hypothesis and experience, the risk of damage to the Samsung sub is almost nonexistent as long as the wiretapping is done well (not leaving naked wires), and the external sub is active (powered). The tap is a parallel connection, so resistance is low. I have tested my theory with another soundbar (Sony), and it is also working perfectly.
@@nh-techdo you understand ohms law? And that the Samsung module is engineered for the original woofer?
@@nh-tech’tapping’ lol. Clueless
How can i connect my passive 12 inch "earthquake" sub woofer to my samsung B550 soundbar?
You cant
@@dbefore7165 well what do you suggest how can I add another sub?
@@RY-yi2rutake the amp module from the sub and connect it to your passive sub
That will work, but it may not give the explosive bass you may be looking for.
I dont understand about audio, here goes the dumb question: dont u need an amplifier for using both sub's with full power?
The Klipsch sub is (active) powered, so no extra amplification is needed.
@@nh-tech thanks ^^
I'm a little confused, it looks like you're connecting the Klipcsch rca wire to an already amplified signal - at the Samsung's Driver? @@nh-tech Would this cause issues for Klipsch's amp? Cheers
It could be a problem if the amplified signal was only going to the Klipsch. But because the Samsung speaker is drawing power from the amplified signal, it weakens the power going to the Klipsch.
Thanks for your reply! :)
how does it sound with the samsung sub unplugged?
I would also like to connect my second xtz 12 Inc subwoofer but it doesn't have lfe input but only stereo RCA how can I do it thanks and sorry for my school English.
You can use an RCA splitter 1 female to 2 male. You can check this out amzn.to/419EgG7. You could also use a high to low-level converter. Hope that helps!
Samsung HW-Q930C or JBL Bar 5.1?
Hi bro my Samsung soundbar Q990C is not working just 1 orange Light is on. I m going to samsung service centers butt he is noy resolving this problem i m just 2 months ago buy the Samsung Q990C soundbar. Pls help me Thanks
This mod is wrong on ever level, please get a basic grasp of electronics and just swap the amp module from the Samsung with the new sub, that’s how it’s done
Hi, Mr. Electronics Expert - the amp in the Samsung sub is rated 26W and you want me to use that to power a 400W driver? In another comment, you said to replace it with a new sub: from where? Do you realize you cannot just wirelessly pair another subwoofer to another soundbar? You again said that soundbars are not for large spaces: does that mean you shouldn't own a soundbar if you live in an open-concept floor plan? Better still, have you seen the Nakamichi shockwafe and Drangon? How about Sonos Arc, which allows for additional sub? I appreciate your concern, but what you know is not the only way. The basis for knowledge is so that you can think outside the box, when necessary.
@@nh-techthe basis for my knowledge is being an electronics engineer with a degree in audio engineering and 30+ years experience. What’s yours?
@dbefore7165 If my working results in the video could not convince you, why would I waste my time giving you my credentials? Do you need my resume before accepting that my method works perfectly?
@@nh-tech its just poor performance as any audio engineer would tell you.
@@nh-techwrong wrong wrong. Electronics obeys laws of physics that you seem oblivious to. These soundbars work by wall reflections, if the rooms large then the tiny drivers struggle to work properly for pretend surround. I’ve said my qualifications, what’s yours?
Or you could just buy a HDMI audio extractor and run both subs without voiding warranty!
Samsung would never know you did this.
Die arme Endstufe. Das wird sie nicht lange mitmachen.
