What's uuuup
I like using bass boost in order to give the bass a little more emphasis .what I do is adjust the bass boost to an average level then set my gain properly.
I love this video.. thank you..
The only time I use bass boost is when I'm using a lower wattage amp.. 500 to 600 RMS.. but I include it when I set my gains etc.. I used an oscilloscope to make sure There is no clipping whenever I add that boosted frequency. I never set my gains 1st then bass boost like this video shows.. I have learned so much from EMF.. and I appreciate these type videos.. thank you !!
Everyone I've seen that say "don't use bassboost" never talks about setting the amp with bass boost on.i personally love how those punch and mtx amplifiers sounds with bass boost on
smtyson You are right but at the same time.. it can make the bass sound muddy over a certain db level.. and this video shows the negative impact it can have if you don’t use the setting right because it will clip your subs.. I might use 3db and nothing more and I apply it when I set the gains 3db is enough but I use it on amps that is around the 600 watts range.
That’s what I did. I have it set to 6db on the amp and 24db on the deck and I set the gain after I set that. Bass sounds great and lots of SPL
So glad to see another level headed video from EMF Audio.
Very informative video, thanks for showing what happens when using the bass boost. Thanks Sean!
Awesome video! I have tried to explain this before and now have a video to refer too!
I’m glad someone finally put out a video with all the information on bass boost, I don’t think you changed anyone’s opinion but…good discussion.
This is a very informative video and confirmed what I had suspected. I own an Audi S5 Sportback and felt the bass was sorely lacking, so I recently had a JL Audio 10-inch sub installed in a custom enclosure with a 500/1 monoblock amp. I was initially underwhelmed because the bass was totally overpowering. I checked the amp and saw that the installers had turned up the bass boost about a third of the way. I turned it all the way down and the system is amazing now.
Overpowerimg bass is underwhelming? Lol
I professionally installed form 1988 to about 2001, 2 ways I have used bass boost, 1. In a factory radio where we used a line out converter and the factory radio was tuned a certain way. (most factory radios are not 20-20,000 hz) 2. using an amp for midrange and were lacking snare drum pop. you can gain a little in the 80-100 hz zone and pick that up. Strong midrange around the 100 hz zone is hard to get out of 5.25" driver, A LITTLE bass boost helps. If you have a full 40 hz signal going into the amp, it is being amplified already, you cannot boost anymore power from that amp that is already maxed rail to rail , you just get harsh clipping. A 100 watt amp with 18DB bass boost will never be a 150 watt amp. Hope this makes sense.
Awesome video as usua!
I had a kicker kx1200.1. Extra battery and 1 faraday cap. It was so nasty I had the amp gain and bass boost all the way down. 800.4 gains at a quarter of the way up. Sounded perfect.
I can’t tell you how much I appreciate this type of info and in particular this specific subject. Made a believer out of me. I just came back inside my house from going to my truck so I could go ahead and turn the boost off on both my amps. You are fucking awesome bro.
This is clear definitive proof of what Bass Boost does. If you need it then you will know you need it. If you don’t know if you need it then you shouldn’t use it.
In my personal experience, bass boost changes the way the bass sounds and I personally like it moving the air a bit, so what I would do is to ensure that the gain is reduced proportionately. For e.g. in this case the threshold voltage for the amp is 40V, if one increases the bass boost (say 3-6 db) it will also increase the voltage thus causing clipping, so if we were to reduce the voltage back while the bass boost remains ON, to 40v using a DMM it will not clip and still sound different / better (depending on personal choice) than before but not damage anything. Having an oscilloscope (or use of alternate methods - available on youtube) to check the clip will definitely make it even more fool proof.
Great video
wouldn't variable bass boost be useful for boxes tuned really low like in the low 20s and compensate for the loss of higher bass around the 40s-60s by boosting a few db around 50hz?
Only skilled and passionate people know how to set bass boost etc to match their system.
Exactly but at the end of the day Its just all about balance between gain and boost
Thanks!
Lol. Love the humor in this one!
First video I watched of your and this was extremely helpful. Thank you but what about the audiocobtrol lc2i?
The LC2i has a function in it that is to compensate for a signal deficiency. It is boosting bass, but it's doing it at a rate of signal loss. Some factory HU's will reduce bass as the volume goes up to prevent blowing the factory speakers. That's why it exists, it's restoring the signal loss to the sub(s), in the end it's a flat response.
I use no boost to set up, but I set up with rebass/boosted songs. Then when I playing classic rock or an old school song, I use the boost. But I never really go above 1/3 boost or I get distortion.
When amp has a clipping indicator light or bass knob When it shows clipping would lowering the gains is best? Better off not using any bass boost to be safe?
If you have an amplifier with adjustable bass boost frequency (like from 30hz to 80hz) how would you determine where 45hz would be? I used the cc1 to set my crossovers and subsonic filter, but how would you set the bass boost frequency.
The easiest way is to use a DMM on AC voltage. Turn the amount of boost all the way up (to give the biggest change in voltage) and where you see the highest voltage is the frequency it's set to.
I had the bass boost set to 3-6db for years before I heard not to. To be honest it actually sounded better than when I turned it off but then again I had the gain set low (less than 100 watts without boost on a 400 rms alpine amp) I doubt it would hurt anything in a situation like that
Have separate level control (through the RCAs to my monoblock) and bass boost control. I find I rarely turn the bass boost up for most music I listen to (rock, country, etc), usually only for some hip hop/rap songs where it actually increases the sound of the bass in a good way. Thing I dislike about my Pioneer monoblock is the bass boost is only at around 50hz, you can't adjust the frequency. I like having both controls, I find on FM radio I have to turn the level control down because the stations tend to have their bass turned way too high. Been trying to convince my buddy that his bass boost knob is NOT a level control for his amp, which is why it sounds horrible turned up and not just louder.
Thank you so much for this informative video.
I have recently installed low RMS subwoofers on a 5 channel amplifier and could not for the life of me figure why I have clipping when I turn up the bass boost on my equaliser, even with the gain set right down to zero on the subwoofer channel of the amplifier.
Turns out my equalizer has up to 18dB bass boost. My amplifier would get really hot with the bass boost on the equalizer turned on (bass boost on the amplifier is turned off).
I will set the boost on the equalizer to 3dB and set the amplifier gain to get a clean signal. Then use the the equalizer with the bass boost turned off.
This might just save my setup and give me the clean bass I so very much desire.
Like I theorised with my brother before finding this video. Bass boost is like having a big turbo. Maybe you're safe at 14psi but the boost takes you to 25psi and you don't have enough fuel flow to account for this added boost then 🤷♂️ you're not gonna have a good day.
Just because the boost is there, doesn't mean it's safe to use it all.
7:15 "i'm really high right now" I am too I don't think I'll remember anything this guy said.
I do see a difference in the way you test , you use a roll in , where I use a momentary switch in the RCA cables full blast for 1.5 seconds just long enough for the meter to register 👍🏻I like what you’re doing keep up with the tech videos
There are legitimate reasons for rolling in, from an amp functionality standpoint to a sub durability standpoint.
I have my bass boost turned about 5% of the way up. Just so I'm not overdoing it and it's not completely off.
Could base boost help my 4 channe amp I set the gains correctly but I have no midbass and the highs sound harsh
can u please explain bass boost on an amplifier vs subwoofer level on a head unit
I have two 12" 1200W RMS total @ 2-ohms subs and an amp that puts out 1100W RMS @ 2-Ohms. However, I only have a 90A alternator.. So I was thinking of setting the bass boost to 6dB (halfway mark) on my amp and tuning the amp to 1000W. My logic is I can't run my subs at 1200W cuz my alternator can't handle it as well as my amp, so if i push the bass boost a bit and tune the gain knob to 1000W, that will give it a little boost to aide in the lack of running at full power. In the future, I plan on upgrading to a higher amp alternator, and getting a more powerful amp; when I do, I would have the bass boost all the way off when tuning. Does this sound about right?
Bass boost simply takes a set frequency and makes it louder, it doesn't make it collectively louder nor does it make it draw less amperage. You might be surprised how much power you aren't making. With a good battery and big 3 upgrade there is no reason your 90 amp alternator shouldn't run a 1,200 watt amp.
I use like 6db bass boost but im running my music off aux cord from my phone, so low input signal voltage.
What kind of oscilloscope is that?
Hello sir, please help me how to correctly set the gain, lpf, subsonic, bass boost freq. and bass boost. I have mono 1000.1 then two 12s - 250 watts dual 2ohms . because my box is two 40hz one box. I hope you can help me with the correct settings of your tone control, I hope you will notice my comment immediately, thank you ❤️❤️
I adjust the bass using the decks sub output. -6 to +6. Works good in combo with bass knob. Used a DD1 to get my gains
Soon you'll see why you shouldn't use a DD1.
@@EMFAudio I did the 40hz test from the stereo and then from the amp with the dd1. The gain barely went up. Amp doesnt get hot. Just for my own info, what's with the DD1?
@@michaelzernie7092 I'll be doing a video on it soon.
Why couldn't you turn your gain all the way down then Max out base boost then adjust your gain with an oscilloscope?
I got a four channel amp..bridged front n rear..at 2ohms..2 p2d2..15's..ported box....
i got a kicker cx400.1 amp hooked to a single 2 ohm 12” 600watts rms, if the amp makes 300watts at 2ohms could i just turn the bass boost up 3db to double it or would it be pointless
Bass boost focuses on 1 frequency and tapers around it. It doesn't add power, it just changes the linearity of the bandwidth. You're still limited to the power it can put out.
On my 1997 Rockford fosgate power 500.2 amps is a bass EQ adjustment is that the same as bassboost?
Yes.
So is there a difference between using bass boost on the amp or using the DSP EQ to adjust the same exact frequency (assuming similar Q width). Aren't they doing the same thing of adjusting the gain of a particular frequency?
If you had the same Q and to the same frequency, bass boost on the amp or a DSP would give the same result. DSP you have way more adjustability though, making it potentially more useful as a function. If you did pick a particular frequency to boost you are doing the same thing except for the peak will be narrower, much narrower. Generic "bass boost" is pretty broad as was displayed.
@@EMFAudio Thanks, and as always thanks for taking the time to make the videos. I Look forward to each one.
I needed a square wave generator like that for my work bench.. Yowch..
I wish that amplifiers didn't come with bass boost. If I want to boost a particular hz. I just use an external graphic eq.
Yes , but more volts on the speaker out for SPL comp , in my experience does get you more spl if the voltage increases with your bass boost , in spl distortion does not matter 👍🏻
I must have more experience than you because more voltage doesn't mean more SPL. A slight clip can give you more SPL, a hard clip can reduce SPL a lot. You know how when you clip it on music it stops getting louder, or even gets quieter? It's because you put more voltage into it and clipped it. That means it's an audible difference in output, which is a minimum of 33% QUIETER. I've tested peak SPL with a slight clip then gone 1 more click into hard clipping and dropped 2.5 dB.
I will say you definitely have more experience than me , what I was trying yo get across, with my experience using Orion xtr 2250s is that I got my highest spl numbers when the voltage on the speaker output was at its highest value, the spl was also at its highest, when I down tuned for no to little clip my spl was lower by about 1.5 dB then when I gain matched all the clipping equal I got my highest spl , on an audio control back in the early 2000s , things probably have changed since then with pressure meters, but in my recent old school spl challenge I had my highest spl with a very clipped amp , I did a 147.2 with a xtr 2250 very clipped , when it was not clipped it was only in the high 145s , this was using clip indicator lights on the amp , maybe on single woofer setups clipping matters but on multiple woofer setups in my experience only the highest voltage gets the highest spl 👍🏻
@@charliefrancis6438 That isn't what I found with my HCCA2100 I used in the old school SPL challenge, and other amps. As a matter of fact, with a Termlab a heavy clip severely kills the score.
I saw your test , and was wondering if using multiple woofers would change the results , in my testing the maximum ac voltage on the speaker output gave me the max spl , if I turned a click or too past max voltage it would drop spl , but only by 2 or 3 tenths of a dB , maybe I am not setting up my gain structure correctly, anyway thank you for replying, and keep making your tech videos I appreciate them greatly
@@charliefrancis6438 The number of speakers connected won't change the result. SPL dropping when you do that is a result of hard clipping.
What if I'm using a cheap head unit and I set the gains so it's maxed out at a lower number on the head unit such at 30 or less? Is that ok?
The numbers don't matter, the only thing that matters is the gain is set to the matching output voltage, be it 0.2v or 6v, or anywhere in between.
Can you make a video on how to add an independent relay directly to one amp? How to wire it, where to get the power from, and it's potential. I'm thinking of adding one to my toggle switch for a more professional quality job.
Do you mean so you can manually control it on and off instead of automatically with the HU being on or off?
@@EMFAudio.....Yes, control it manually.
@@25hztolife86 That's just basic relay wiring, any would do, very low current. 87 would go to your 12v power source, 30 goes to the amp, 85 goes to 12v power as well (you can tie it to 87 with a jumper) and 86 goes to your toggle switch with the other end going to a ground.
@@EMFAudio whats the purpose of the relay just wire the toggle inline done
@@jesummers9084 You could do that with an appropriate switch that will handle the current, but he asked by relay so I answered. Some toggle switches won't handle more than 1 amp and it's possible to have more than that with multiple amplifiers.
And just to double check is the bass boost supposed to be higher or lower than the gain setting?
Bass boost shouldn't be used in nearly all applications. It's relationship to gain setting is nothing.
Good evening,
I have a question that I hope you could help me with since you sell Sundown Subwoofers.
I bought the SUNDOWN SINGLE SUB BANGIN PACKAGE (2000Wrms) 5 days before my 50th Birthday on October 8th from Down4sound in Las Vegas. After waiting 7 weeks to get the call to go pick it up here in Vegas... I Finally got my Birthday present.
🤘🏼😜👍🏼
Now I am having a hard time finding a Sub Box that has the specs for the X v2 15" that I picked for the Bass package that I bought. D4S doesn't carry single 15" sub boxes. From the few boxes that they showed me they only had a huge dual 15" sub box. Other than that they didn't have any bigger than 12" sub boxes. Would you happen to know of a place that sells good sub boxes that are pretty much made for Sundown Subs? After waiting 7 weeks I am Amped (Pun Intended) to get my new addition Thumping/Pumping/Bumping Down the road. 😉.
Thanks
Chico Man I have the same woofer I had to get a box made with the specs for the woofer and it’s ported
I've been wondering what the remote level control for the mono line up of sundown audio really does. Is it a kind of level control for the whole bandwidth or just kind of some bass boosted parabolic response at say 50Hz. Please let me know if anyone has idea about it.
Our amps, as well as Sundown, and many others are an input level adjustment. It will cut the input signal, not add or boost anything. This means it will only go as high as the gain is set and the output isn't colored in any fashion. Not all amps are like that though.
Justo to add more context, the remote knob in many Rockford amps acts indeed as a bass boost (so called punch EQ) and not like a level control, so you better check the manual to know for sure if it is a bass boost or level control.
Well. That sounds good. I've seen specs of some of the amps mostly Chinese hefty stuff. They have mentioned the frequency response vs position of remote knob. I saw the parabolic response centered around 50Hz which sounds weird and looks weird. Thanks for the clarity guys. Keep doing awesome things. I couldn't find such information in user manual of sundown amps.
@@jaiaditya4u My Pioneer is centered at 50Hz also, would be nice if the frequency could be adjusted, 50Hz boost sounds terrible on some songs.
@@ixionn563 which model is it. I'll try to check the possibility to alter that.
So question kinda on the subject. I'm pretty sure I already know the answer but I think it would be helpful for others to see it answered. So you find your max volume on your deck we'll say 47 out of 50. Then you set your 4 channel with a 0db tone and then on your bass amp you want to use some overlap. Let's go crazy and say you listen to certain large youtube car audio personalites and you set at -10db overlap. Now you play your new bass cd which has multiple tracks with tone like bass lines that is recorded at say -4db. Being that everything in the system is set correctly and nothing is clipping and the music track itself is clean this will still overdrive the amplifier into clipping, correct?
You basically described why DD1's aren't useful and how you can always clip no matter how you set your gain because of the material being played.
@@EMFAudio Thank you. I've been arguing with said big name car audio youtube personality about this and he just seems clueless.
@@Supercharged1976 I've found quite a few big name people aren't big name because they know what they're doing, it's because they make videos for 14-24 year olds.
What happens when you back down the gain then add bass boost?
Your frequency response becomes less linear, but unless you do both proportionately you'll either still clip or not have maximum output capability.
Is there any difference between wired bass remotes and bass boost knobs on the amp or do they adjust the same thing? Or does it vary from amp to amp?
That will vary amp to amp. Some are remote bass boost, some are remote gain.
@@EMFAudio Thanks. That explains why I get varied answers depending who I ask.
@@EMFAudio that's just evil. anyway to distinguish?
@@buddykiller Not that I'm aware of, besides the companies history or the owners manual.
Sooo I have a 15inch L7 Q class and a 1200.1 amp and installed the big 3 and some how started to get smoke? Speaker is good and no the gain is not my bass knob. Not a newbie but for some reason with my gain set less than half way and everything is perfect as in perfect wiring runs good grounds good everything. Had it for about three weeks for the same settings for my 12inch just to break in my 15in and my speaker seems just fine but no ships in dfw had meters to set gains to avoid clipping or anything so how the heck do I find out why my coil burned a little bit everything is still ok tho? Why would that happen tho?
Gain isn't a power knob, if everything was fine with your old gain setting that was probably the right setting. But, if you listened to tracks with a higher recorded volume it could have been clipping. Most "enhanced" music is clipped as well.
EMF Audio agreed. I don’t use my gain as a bass knob man lol 😂 I promise y’all that the only way this could of happened was either the big three was installed wrong and once I took it out everything is back to normal. The other fella explained to me very well on how to reset my gain by ear. Trying that later today but this morning at work when I play my system for about 20mins straight through pandora (no enhanced music) and played for to long maybe but with the settings it shouldn’t have done that but it has to be the gain and bass boost are off like I know my bass boost is on and going to turn it all the way off and restart from there and not use any boost
What's your thoughts on the full bridge amps?
I'll have to do some solid testing on the new Sundown SFB line, I haven't liked full bridge at all. Maybe those will be fine, maybe not, I won't know till I have some experience. I'd never use one of those Brazilian fire starters though.
Can you tell me what type of oscope were you using?

i think the bass boost on amps is a conspiracy by amp manufacturers to get newfrens to buy more subs.
@@brightstarlastname2812 was a joke lad.
honestly i much prefer external eq's with fidley bits over the soft eq's offered in hu's. you also get the benefits of a line driver more often then not as well with an external eq.
@@buddykiller external eq to me add more distortions,unless it's a dsp .imo
@@smtyson1650 eqing takes a lot of practice and patience because you don't have the precision of a dsp and yea, you can absolutely make it sound really really horrible really quick. i use a measurement mic to get as close as i can to flat and then tweak everything to just what sounds good to me. the worst part about having an external eq is that everybody wants to touch it for some reason. flat is GREAT for movies and tv shows, but sounds horrible with music. the thing to remember about eq's is that you're effecting an entire band of frequencies and the more gain you add the more dramatic of an effect you have on it so you gotta go back and forth and back and forth. oh, also, your eq isn't supposed to smile at you. if your eq is smiling you're doing it wrong. setting the eq in my house takes forever because it's 31 bands per channel. after it's all set i love it, but if i move my speakers or replace them i wish i'd have gone with a 13 band lololol
I want to see you do this with an audiocontrol epicenter.
I'm curious what it would do.
@@derrickgause8419 most boring 6 hours of your life, trust me.

While I have not tested that, I suspect it could.
@@EMFAudio that was what I was thinking I remember a lot of people using epicenters a lot and sometimes it distorted the sound keep up the good work as always I look at all your videos I think that would be a very interesting video also
I have 2 15" forte's on a BC 2k at 1 ohm gain 100% bass boost 100% and been beating the hell out of them for 3 years now and never had an issue.
video or gtfo
We all run out shit our own way I've always ran my setups balls to the wall and has always worked for me. No disrespect to this video this dude always has good info i just do my own thing sorry but not sorry that bothers you 🖕
That just means you have a huge peak in your response and the gain is set lower than it would be without bass boost on. I've come across people saying certain songs sound great and everything else sounds terrible, and every time it was because they had bass boost cranked.
I'm just a guy who loves extreme bass 💜
EMF Audio thank you for putting in the time for us you rock 🤘
I have it set to 6db on the amp and 24db on the deck. It sounded the best to me there.
You have bass boost up 30 dB in total?
@EMF Audio Yea, with my gain set barely at about 1/4th. I set the gain after. I tried using different combinations with the amp and the deck and 6/24 was where i got the best bass i could feel. It shouldnt be an issue as long as i set the gain with a DMM after, right? My amp is 1500 @ 1ohm , my speakers are 600rms each (4ohm DVC wired parallel to 1ohm). The number i got for the DMM was 34.6. I just set it to that after i set the db. The db makes the number show a lot sooner when dialing the gain. I assumed it does this to compensate for the db being added. Will it mess up my speakers?
i see other comments about epicenters. can you do a video of that or post your comments about them? i have the audio control epic-160 in dash unit
people say epicenters are garbage but i really like what it does to alot of songs that i get 0 bass out of when i dont use it
Most people think they're garbage because they're trying to use it improperly. They're for restoring harmonics in old recordings. For that they work well, but modern music just makes it muddy trash.
Uhhg. I spent 30 minutes thinking my sub, amp, or head unit was blown because the sound was clipping and the 10-30hz response was rolled off. After turning off the bass boost the sound returned to give me bass all the way down.
We need more bass boost on the gain 😆
😂
its an EQ CONTROL !! what dont you understand about that?? of course its going to clip when you add db to a frequency while at full volume duhhh??. im not going to expain the term eq and why it has value on an amplifier
No, it's not an EQ control. It's 1 band, which is why it says bass boost and not EQ, short for equalizer. I wouldn't try to explain something I didn't understand either. If everyone knew it would clip I wouldn't have to do this video now would I?
How do you get big base with base turned off.
The setting is bass BOOST, not bass period. You should have bass as long as you aren't filtering it with a crossover.
I think you misunderstood how it works and when to use it.. As you increase Bass Boost this increases power at the lower levels BUT the amp has a max power that can't be exceeded so you get clipping.. When you use Bass Boost you need to reduce the gain to stop the clipping. The result is lower lows but less total volume. When BB is applied it applies it on most amps at about 45hz and it linear reduces as the frequency goes up. So it works best on speakers that have a linear drop off.. so is best with door speakers and sealed enclosures. And obviously if you can get to 45hz (large sub) without BB then it's not needed. BB is therefore best deployed to small speakers. I use it in 6.5 inch door speakers.. Would i use it on a 12" ported enclosure.. NO
What key are u moving for the bass boost? Can’t see it
The one labeled bass boost.
EMF Audio my AMP only has Bass EQ, Sub Sonic, low pass, level. What setting will increase the bass I’m new to to the audio stuff
@@centralcoast6720 "bass EQ" won't increase the overall amount of bass, just a narrow band of bass at lower volume levels. The only thing that will give you more than you have overall, is different equipment (sub(s), amp(s), enclosure, etc.)
Can the clipping be herd clearly?
A very slight clip, no, a hard clip can absolutely be heard. What you saw on the O-scope can definitely be heard.
yeah I don't understand that if you turn off the bass boost where's the base it's gone I've had many amps soon as you turn off the bass boost all the base is gone
That sounds like you have other settings problems filtering out the bass.
I mean it sounds good to me when I have it on but I have my gain on 1 and bass boost on 3/4
I've always use bass boost,usually 18db..the difference for me is that I turn the gain down.i only want to hear the lower bass
You know, you could achieve the same thing by turning the LPF down, while not changing the curve on the bass frequencies you do want.
That's right if you're going to use bass boost crank the boost all the bass boost turn your gains down
@@EMFAudio it won't sound the same.
that's how they say to set it,using bass boost in my mtx1501d manual also
@@smtyson1650 Exactly, it will sound better because you have a flat response in the range you want.

I don't know about you but when ai put bass booson, my fingers get slimy and I smell fish. Join the movement and let us all throw our bass boosts out in the trash. Since you hate then, I will agree.
So I should crank em up?..😁
LoL, all the knobs to the right 👍
you have to reduce the gain when you use bb

Kevin Redd name? or link to the scope
hmm, you only have to adjust the input level, and there´s no clipping in the signal with bass boost
yea, but then what's the point? you'll be underpowered outside the range of boost. that's what eq's are for.
Bass boost causes clipping if you change it after the gain it set.
If your box is correct, it should play a large range equally.
@@EMFAudio what if u use the dd1 to set gains then use the dd1 again when adjusting the bass boost ? Won't that allow you to get Max gain n max bass boost?
@@hellraiserharry I'm not sure you understand what a DD1 is for exactly, but soon I'll be posting a video of why it's a waste of money.
Clippn that signal for science:). Ya I think bass boost is for suckering teens and newbies into buyn amps and blowing subs with a clipped signal making them think there amp is “powerful”I don’t know why amps even have them imo of course. Cool vid
Do y'all think they should make an amplifier, head unit and Source unit that's honestly unclipable and undistortable? Why can't they make things easy for us the consumers instead of us wasting our money constantly buying new things that we honestly don't know much about it but then again we learn but we still make mistakes time and time again just saying? I mean not all of us know how the tuna amplifier or know how to work it not many of us have friends or access to the internet. When I was younger like at the age of 16 I didn't know much about tuning amplifiers and yes I did burn out a couple of speakers but I never fired the amplifier. And time I learned when my dad taught me but what I'm trying to say is not all of us know how to do this type of stuff that is out today. I hope this makes sense if not don't worry about it.
Sean keep up the amazing work though for EMF!
It would be possible, that technology is used in the home and PA world. But, it adds cost and everything is cuthroat as it is. There would also be a huge amount of returns for products that aren't broken because of audio cutout.
It works good on a sub that has a really low flat frequency response like an x12 to give it more kick. I just add it in till it kicks harder and reset the gain.
X's are actually frequency deficient, not flat. They fall off over 45 hz or so.
@@EMFAudio agreed.
I hate buying a amp or tuning a buddy amp or customer and the other person has the bass boost on. And when you set it for them they go it was hitting harder before and then after they leave and they call you again and they said a problem happened and they bring it back only to see they turned up the boost again and say they didn't mess with anything
Distortion sounds louder, so that's why they think it was louder before. I know what you're talking about though. When I used to install professionally people would blow subs up in a few days and come back. Every time it was everything wide open and "my friend said he could get more out of it and you didn't install it right".
Is there a such thing as a "volume" switch on a amp theres gain and gain is no way anything like volume as much as anyone would like 2 think. does sundown actually have volume knobs on their amps ? I cant see any lettering on those little small knobs and no this is not a joke
Also imo bass boost is just a phoney bologna marketing gimmick the 1st time ive seen bass boost on a amp was on audiobahn i bought off ebay it blew in a couple of days and only other times ive seen bass boost besides the sundowns is on those cheapos on amazon like boss, planet audio, crunch, new ppi, crap . Or maybe i have and not noticed i know it starts sounding like crap once you start messing with it
@@treezy206 Sundown amps are called "bass knob" and it does modulate volume, sort of. With that knob all the way up it will never go higher than your gain setting, so every position in that knob is a reduction of gain. So, it's not so much a volume knob as it is an input reduction.
Thanks for just saying don’t use the main reason I have one🤦🏾♂️😭😅good to know🧐
That was cool to see, other than don't use it.
I always tell people don’t run bass boost/loudness on there deck,amp etc.
How do you get bass?
Jermane Birchum by matching maximum clean volume from the deck rca to the gain on the amp. With a o-scope. dd1 etc.
So your just running off gain?
Jermane Birchum. Gain matched cleanly from the radio to the amp which in turn puts power to the subs.
On my deck the loudness is in three options. Not only that I can adjust the gain in the amp in the deck via sla option on top of that I can set my sub channel to non fade and it has its own built in high and low pass filters . So I can set my loud to boost at low volume and tappers off as I crank the volume. This way I can run no amp if I wanted to for my front and rear stage( I have amps going to these) boost certain ranges and ignore others allowing cleaner signal to the speakers with out messing with the signal going to the sub amp. At my amps I run zero boost as I have to signal voltage fairly high but under the highest input specs for the amp. At this point I reset gains and tune my eq's and filters . I know my deck at this setting clips at 55 out of 60 . I tune max volume to 50 and touch up my gains by ear and then adjust eqs by ear. At this point I can play louder than I like with out clipping or noticed distortion. I set it this way due to the different styles of music and formats it's sent on . Once I select radio or CD I have to do the same as they each have their own parameters .
Isn't that called a square wave🤔 I've been into music production as a hobby for a wile and the "round wave" is called a sine wave and a "square off wave" is called a square wave. The difference is the "sound of it. So developing sounds for everyday music on production software. Technically they is a lot of square wave sounds in music. That being said, seeing a o scope start to square off of a smd dd1's light start to come on isn't that developing " the sound you want to hear" come from your subs, like music production..... I get the whole ohms law ect..ect... volts to watts how many watts a driver can take. I don't have a o scope so I don't know what the wave would look like but I know on a dd1 if you compensate the main level on amp and use the dd1 for boost until the light comes on and back off its still good.but again I have seen the wave it makes. And isn't a o scope a infinite level on a chart and it being "start to square off" just become another process of engineering SOUND.....
I'm not disagreeing or saying I know it all just my 2 cents just saying is that really clipping.i like to learn from others too
Yes, clipping is a square wave and a sine wave is "round".
All I’m saying is look into studio music, besides turning that bass boost like that is the same as turning the gain it’s going to clip lol.
I noticed that if I set the gain to the bass boost clean I needed less gain and if you set the gain first clean then you needed very little boost and it would stay clean…. That was on one branded amp. I had another that off I wanted the boost I had to compensate. Does make a difference at least I noticed in my pickup with a under seat dual 10 in the back where space is very limited. 1.4 cu …. Sealed!

The only way i can get my system to play different kinds of music is to use boost but you must set gains at the worst case scenario... Its not a magic knob... I wish this video showed the clipping going away after gain was readjusted
The gain was never adjusted, it was only bass boost and frequency. If boosting is the only way you can get it to play different kinds of music, you either have other settings wrong (like subsonic frequency or crossover) or your box isn't right.
well dam I personally dont use bass boost...My buddies on the other hand do they kinda go a wall with it...lol
Share this video!
@@EMFAudio I will 👍
I would have to agree to disagree! I've been messing around with bass since the 80's when bass boost was none existing! Different amps back then you really didn't need it. Take for instance the old school Punch150. Need I say more! Fast forward to now to higher wattage amps, bass boost is horrible depending on your equipment and settings! Settings are key! Bass boost is possible and not the Grim Reaper of audio if you properly set your gains and head unit. Everything don't need to be maxed out. The more you turn bass boost on the more you turn your gain down! A quarter to halfway depending on your crappy equipment! 😏The sound difference will rock you. I never buy or install an amp that's higher than my speakers! Your asking for it. 1000 watt amp 1500 watt speakers that way I can play around and not do harm. Bridging would be the closest you want to push speakers in this case. Not Bridging 2000 watt amp to 800 watt speakers! Bone head ideas! 🤪🦴 ... because your going to always be tempted to crank it up a notch..don't let people scare you into not using bass boost!! There are proper ways in tuning it. in all its about SETTINGS..SETTINGS...SETTINGS...
Manufacturers need to stop with the bass boost and start putting in clip lights and or remote giants with clip lights.
Sundown has been putting clip lights on amps for many years. I do agree it should be more common, but people will ignore them anyway.
@@EMFAudio didnt rockford fosgate start doing that with there Power line?
First bass boost on and then gain...
Or never bass boost.

Aww u shoulda tried lowering the gain and just using bass boost ... Do it for the next vid play with it...
I think in a video I showed why that was bad, in how it actually boosts in a non-linear fashion.
So never ever use bass boost?
Not necessarily never, it has it's place, and rarely will it be used it more than a 3 dB boost. In most cases no, you shouldn't be using it. It's there to boost a deficiency, not go above and beyond.
This video is garbage, look here it's a nice clean signal. Now I turn it up and it's clipping, now I'm going to add bass boost, and look see it's still clipping, now I'll turn up bass boost on the clipping signal and see it's clipping even more. Thanks dude.. maybe turn the amp down so it doesn't clip and then show what happens with 5 db bass boost. Anytime you boost any frequency 9 or 18 db your going to make a mess of the signal. Grab your equalizer and turn up your 17khz 9 db and tell me if it clips . When the signal clips..
I’ll take a no bass boost
