Any video like this is Jacob for all your first time installing viewers is good. Good stuff🤛🤛
FML, I always wondered how ppl managed to run multiple amps in their Vehicles and THIS vid just smacked me upside my head 😅😅😅 thank you so much for sharing this info!!!
Your welcome 👍🔊 glad it helped
Hey Jacob it was nice to meet you in person Saturday at scraping the coast I’ve been following you for a few years now and your videos have helped me a lot
Hey Charlie nice seeing you at scrapin man. Thanks for always watching and glad to help.
Your a life saver. I've been looking everywhere for this information. BIG THANK YOU.
glad it helped
I have a issue doing this in home audio. from a Y splitter off my EQ to 2 Kenwood KM-209 house amps. I don't always run both amps and I noticed if I only have 1 of the 2 amps powered on the subwoofers don't move the way they should. They almost move like they are free air or something, if I turn the 2nd amp on, they are all normal again. Why would this happen? I've been trying to figure this out for years. I've tried different sterios, different rca splitters and cables. Any help would be appreciated. If I leave both amps on every time I want to play 1 set of speakers and I don't even need to engage the speakers with the ab switch, as long as both amps are on, it's fine. It's so strange.
Thanks man for sharing love your work.
Your welcome 👍 more coming daily
Hey man your system looks great!!!
Thanks Krotos
This is great! Thanks!
Glad it helped
when I did that using the splitters it cut the signal in half
I saw someone on FB comment that splitting RCAs lowers the output voltage 😆😆
Does having those 2x4s in the back of the wall help with vibration meaning all air flows to front better?
It’s a walled system sealed from b pillar, those in the back are for bracing support
Hello, thanks for the video. Question can I run two amps of one PC power supply?
Idk anything about pc supply sorry? In a vehicle yes
Nice to meet you 😊 ☺️ 🙂 🤗
Do your RAC's go from the head unit to the bass knob then back to the distribution block? Only asking beacuse you said rhat they go straight back and some people might get confesed as to how to add the bass knob.
Yes bassknob to distro
What he said ;) bassknob firet then back rca
I have an amp with 1 RCA input. I want to install an outline converter for a pair of rear deck 6x9 speakers. Can i use a distribution block to install the converter? I'm thinking 2 Y splits one from the HU to the output converter. I'm not sure. Great video. I learned a lot
Signal goes then through both rca connection points so dont se a problem
Thanks for showing this. Can i do the same thing with high level?(no rca connectors/stock head unit) I want to get signal to a mono amp for a sub and to a 4 channel amp to drive my speakers.
Idk how to do it without rcas, unless going Bluetooth
looking at doing two subs although cant find a amp rated for the power level would it be possible to do this and run each sub on their own amp?
Correct, that’s what I did here with 4 amps and 4 subs.
i have questions about connecting two or more amps using a bass knob , does it affect sound quality or affect the strength of the volume?
No if you use high quality connections. Seen 1,000s of competitors use bass knobs without problems long as connected properly. Knobs do ware overtime so can down the road become a problem if not replaced.
Just bought a audiopipe 3003rca splitter because I wanted to install a third amplifier, it has a rear/front and sub input. My question is do I connect rear/front and sub from my aftermarket stereo to splitter input and another set of rca's on output to my amps?
yes but make sure the proper signal to proper device as different outputs from sub and speaker outs from HU.
I like Daisy changing it's much cleaner and easy when your amps are close together but not with mids and high amp
I have two monoblocks and 1 8channel amp. My headunit only has 1 L&R output. Will i have to use splitters from the headunit and use one distribution block for the monos and an additional distribution block for the multiple channel amp “for speakers”?
Correct, you need separate signals for the speakers vs subs
question. One set of RCA cables (L&R), split into 2 lefts and 2 rights. 1 L&R hooked to 2 channel stereo amp. 1 L&R hooked to mono amp. Will the L&R signal be combined inside the mono amp? Therefore combining the L&R signal at the 2 channel amp as well? Causing a loss of stereo?
You want to make sure your subwoofer/mono rcas are SEPERATE from your stereo. You need seperate signals for bass and speakers, then it works fine like you said otherwise.
@@JacobViral2 Thats what I thought. However I had enough y adapters so I tested it and to my surprise I still had stereo.
So I understand the rca Y splitter.. my question is, I have two separate sub woofers, each speaker has its own built in amp. So do I just splice Into my original power, remote, & ground wire to plug into speaker #2 ??
Always new runs for power,ground,remote to ensure proper electrical and safety. Use a 2nd battery and multiple 1/0 runs from front to back.
My head unit has a mono sub output, but only one stereo output. I want to add a four channel amp for my door speakers. Am I going to be able to achieve fader control with only one stereo output?
Probably will want to upgrade to a rear & front plus sub rca signal rca triple sets so you don’t even have to worry about splitting.
when should i upgrade my bass nob, rn i have 1 18 but im planin to add another an 2 10s
Bass knobs aren't required for the amps but helps for ease of use and adjustment, It is up to you but I think it's good to upgrade asap since it helps
I have two amps both 2 channel and im trying to run a sub and four door speakers what do I do
Stereo head unit should have the rca output for the subwoofer amp and the rca output for the rear/front speakers for the other amp.
Would this allow me to use two headphones (one on each amp) at the same time?
what do you mean by headphones?
Hey, i have two amps, one is 4 ch and one is monoblock. I have 4 rcas in head unit. Do i have to connect both amps off the one rca channel from head unit or can i run one set of rcas to each amp?
Run one set of rcas to the monoblock bass amp to sub rca output of stereo, other 4 channel can use the front/rear rca
@@JacobViral2this is crazy i just bought a marine amp for my PA’s i just bought and i did everything you said except i put a y splitter on the end of my monoblock amp RCA cable that went into my head unit for my subs and then i went to run my 4 channel amp RCA’s to my head unit and wired them front/front both ways and then when i went to start my truck to see if i did everything right and my truck wouldn’t start😂
i have another question for you that you also might be able to answer, i need to install a on/off switch in-between my remote turn on wire. so my remote wire is ran from my head unit into my monoblock sub amp so i got some extra wire and put them together into my monoblock amp and ran it into my marine amp. in-between the 2nd remote turn on wire, can i splice it and just stick the on/off switch in between. And would it only turn off the marine amp which is the 2nd wire thats ran from each amp??
This thing is Awesome. Thank you so much I didn't know this existed and this makes life 100x easier. You are the man. I've been subbed for months on your main channel and just came across this one. deff subbing here too
Glad I could help and your welcome. 👍 welcome to my 2nd too.
@@JacobViral2what about if you have 2 sub pre outputs can you use a dual RCA or would you just need a single RCA still
@@HellaBassTBO What stereo has 2 sets of subwoofer preouts? Never seen that before. Signal splitting should've be a problem I would think dual rca then
Am i able to hook a class D amp and 4 channel amp to rca block than run the rca to unit?
You want seperate rca signals for class d vs. class ab 2/4 channel amps. 2 different rca blocks
Had a quick question if anyone could help. If I have a 1 to 5 rca distribution block would that work for a 4 channel amp as well as a mono block amp? And does having a 2 to 5 change anything?
You need a separate block for different rca audio signals as you don’t want bass going to speakers.
@@JacobViral2my headunit only has one RCA out which is currently connected to my Sub amp. If I want to add a 4channel amp for door speakers, will I need a better headunit with multiple rca outs?
@@STELLAR_QRU Correct, you need a front/rear and sub out rca head unit, upgrade.
would this also apply to 4 channel amps since i’m trying to run 2 4 channel amps and one sub amp
Yep, seen some people run four 4 channel amps one per door.
I have 2 1200watt amps..if I plug both of them into the distro box will it send 2400watts out or will they both only do the 1200watts a piece they are rated? In other words is this like strapping 2 amps together?
Your power shouldn’t change, that goes off your ohm, amp settings, and voltage supply; not the rca distribution. 👍 1200watts per amp
@@JacobViral2 kool so once i plug both 1200watt amps into the distro block itll basically be like have a 2400watt amp....right
@@yellaboidre9905 if you got enough alternator to make 2000 watts should correct
Wiring a Kenwood KMR M332BT receiver to a MT-700.1 amp to drive a 10 subwoofer and from the 700.1 to a Kenwood KAC-649S amp that drives 4 speakers. I have run a splitter for power and ground to the two amps. I too have run a jumper for the remote power. I have connected the RCA cable from the receiver to the 700.1 amp. On the back of the receiver are three RCA connections. Front, back, and SW. The confusion is running the RCA's for proper connections.. Can you advise??
SW=subwoofer amp(monoblock for sub)
Front and rear speakers for a 2/4 channel amp rca.
@@JacobViral2 thank you, so nothing from one amp to the other as far as rca's?
@@drewaloe113Your sub amp Must ensure to be the RCA Outs that are made for subs, then the others for your speaker amp. Goodluck
How do i hook up my 6x9 to my amp I already hook up my two 12 and amp i hook that up with a in line output converter so i need help hooking up my 6x9 and amp am running two amps
aftermarket radio with speaker front/rear
Is thr a vid on how to run power/remote wire to all amps??
Check playlist: ua-cam.com/play/PLkYp1Fj-99b0pFNxaohIxCaer8VxQVZ2j.html&si=5te3_K70_rXgTnOB it’s simple as daisy running from battery/unit.
Looks good is it the same with the remote wire to turn the amps
You can jump any remote wire as many times as you want. Remote signal only requires very very little power
Yes, but I suggest a relay as head units have a Amperage limit as mentioned in their manual. Just posted a video on relays actually lol.
How do I set my gains I have two Skar 1200.1 chained together and I cannot get the gain right I have an o scope I just can’t figure out how to set it because the second amps gain movez and the first one moves I put both them to clipping sepperately hooked it up and it sounds less than one amp alone
Could be your ohm impedance changing from 2 amps vs. one amp. Sounds like your doing fine tuning gain with device and just need to have amp wired ohm right at 1 ohm
@@JacobViral2 thanks jv but when I turn my bass knob up it turns the bass down ?
Any ideas what’s wrong I have my negatives bridged on my amp
@@way2oppy147 that’s very weird, I would suggest not chaining(strapping) both amps together and set each amp deprecate and match. That way not issues in the chain matter as trial and error. Try it without a knob also, could be a malfunction or error.
So a question how much signal loss you have?1 rca spliting cant get full output from the radio to all the amps the same signal power..
Hmm dont buy it that voltage stays the same unless junction rca box same some kind of"amp" inside like lowering the impedance to make better voltage...
Signal stays the same no issues and voltage remains constant. Think like battery, the whole vehicle is constant 12v range.
do u need ground and power wires to run to the 2nd amp ?for it to work ?
Yeah every amp needs its own power and ground and remote signal to power on
@@callmerona2567 thank you
Is this concept the same with a crossover...what am saying is can I run 4 Amps on a 3 3way crossover 2 door amps on rear of crossover my horns are on the front and subs on sub
Yea since the rca is just a signal out
Thank you
I have 3 amps, and what to connect them to system controller, pls how can I go about this?
Aftermarket radio with rca outputs to the distribution block as explained in video.
I installed a third amp for mids
After I installed the amp my bass sound went from 100% to 10%😫
Any ideas what check ?
Make sure you separate rca connections for your mids/highs from your sub amps. Also you are pulling more current with additional amps so need more alt/battery to support. could be many things
How would I use this for two 4 channels amps?
Probably 2 distributions blocks, one for front rca channel and one for back rca channel
If i need to install 2 amps in my car what rca do i need ??
Use a distribution amzn.to/3KqBvZA for best install process and connection quality, ysplit works as shown in video too
Thanks bro now I know the answer to my question is I need a Y splitter
your welcome glad to help
Mannnn, @JacobViral , I thought this was going to answer my question: Ohk So, my head unit Sony Xav9000es has 3 sets of RCA's... Subs + Mids + Highs, and I have a 2 amplifier system right now, Jp23.v2 + MTX Thunder 5604 (for Mid's and High's) So needless to say im utilizing all my RCA's out the back of the radio now, all my door speakers don't play sound , I guess cause they're not amplified -but what if I have amplified speakers but I also want to run my door and dash speakers off the radio power.... What I can have the best of both worlds "and use my RCA's to send the signal to external amplifiers "and" my speaker wires from the radios internal amplifier ?
Sounds like your doing everything right? Head unit power will not be as loud as your amplified speakers. You would have to run wires to each speaker and amp for more output.
@@JacobViral2 so my question is I can’t run, my door and dash off my radio (cause they’re stilll hooked up) and also run my RCA’s amplified with amps to my aftermarket speakers… at the same time? (RCA’s out and speaker outputs simultaneously?)
@@jahcousteauu_STAYinSHAPE You can run speakers from head unit power at same time as rca output amp speakers, yes.
Thanks for the Voltage staying even comment. I was wondering. The one thing you should have mentioned was how to specifically connect the 2 RCA cables to the split lines. Some people might try to connect the lines to their new amps and have both right channels going into both Left and Right of one amp then both Left channels going into left and right of the other amp. That could be tricky if you don't know what you are doing.
Glad to read this. So when you do split how he did for Left side goes to both amps left side and Right side would go to each amp Right side versus if you plug say Right one to one amp thinking left and right its wrong and same if other one. So essentially each Y from one side goes to 2 different amps correct?
Can u use this for 4 channel amps or just bass amps
Same concept for either/or 👍
@@JacobViral2 Thanks Brotha
Won’t this set up play all the speakers like it was a mono set up? I’m trying to run 2 amps but only have one set of rca’s on my aftermarket headunit. I know certain songs play only on the left or right side and I still want to be able to do that
You should still be able to do left/right as that’s why there is 2 rca connect points.
How do I connect a 4 channel amp and 2 Channel amp 2gather ?
Use a rca distribution block amzn.to/3TkR8Hi like that, one in from stereo and connect to the amps using one signal.
How would I run a 4 channel and a 2 channel amp on the same head unit
Figured it out I need a equlizer
Using this concept would work
Would this work for a 4 channel amp?
Yes it should do same concept
Hy, sorry but i dont get how i can connect my amp to another, i tried throu the rca splitter but it didnt really work, i only have rca out on one the amp that i want to connect to the other one. Now i have seen many videoas showing how you connect the pre amp rca´s to another amp, but i dont get what he uses those splitters for. Can anyone explain to me what the splitters are exactly for please?
It gives you 2 routes vs. 1 run from a single rca signal. It just splits into two rca from a single. Video explained
@@JacobViral2 ok i get that, but in order for that to work, the amps must have an rca our right?
@@christiandenaro5140 input only, you can split rca signal from your aftermarket radio to X amps.
@@JacobViral2 shure, but i dont have an aftermarket radio, now i tried from the "phones" out to connect to the other amp, but apparently it switches left and right channels for whatever reason. Anyways Thanks for clarifying this for me man!
So a bass rca coming from head unit going to the bass knob then from the bass knob to the amps?
Man all I can find are 1male to 2female splitters. Anyone know of a 1female to 2female?
Does it have to be the same watt amps ?
No it’s just a rca signal so multiple sizes is fine
I set my splitters up the same way but i plugged my splitters right into each amp. One problem i have is that only one sub works and the other gets no signal. Anybody know why this is happening?
Could be a lot of things from bad wiring/sub/rca/amp/etc. check your signal at each point and ohms
Because if you followed how he did it one amps only getting a left input and the other amps only getting the right Chanel in put
What's up Jacob my name is Ryan here's my situation currently I'm running a stock head unit and I have a broken 4 output RCA converter it's going to be a month before I can get a new one however I have a spare but it's a single output ,however that single output only one channel is working, and I have four amplifiers, so I have a y splitter coming from my converter going to 1 amplifier from that amplifier I have a exact one which I'm using a output from that amplifier running to the twin, then from that one that output is going to my 4-channel amplifier. Now for some reason when I hooked up some more wire connectors it doesn't matter from the converter or from another amplifier as soon as I go to my fourth amplifier the whole system sounds wack so it sounds decent running the 3 amps however I want that fourth one so I want to run another RCA converter however but I want to know is if I can run one channel out of my head unit the ties into both left and right of the RCA converter or should I just run that one channel of my head unit to one of the left or right of the RCA converter then use a wire adapter like I did with my other RCA converter? Sorry if it sounds complicated but that's my situation I was just curious about and if it doesn't make any kind of sense then don't worry about it but I just figured after watching your videos I would shoot you that inquiry LOL thanks bro

How would I run it in running an equalizer?
Split after all other devices, so signal is utilized post adjustments
@@JacobViral2 sorry I’m new to this. What do you mean by split after all devices?
What's the purpose of having an amp in and out for your RCA's on a 4-channel or a 2-channel class d etc on sub amplifier where it says amp in I thought that your RCA's go to first amp then where it says amp out you take them RCA to next amp and then if you want to add another amp on top of that or more you just jump off the last amp that you have your RCA's going to so in order to get your high amplifier to work right and sound to come through it without using the high input jack to the speakers or the low input jack for the subwoofers if you don't have RCA's you got to do a pig tail like you have here and you can just go off one set of RCA's you can just use your sub RCA create 2 RCA's coming off that to your high and then two coming off going to your sub and it doesn't see a difference I always thought that the sub RCA was made internally different in the head unit specifically for low bass only type of frequency the mids and highs free different type of frequency through the RCA so basically you taught me something no matter if I got four sets of RCA's coming from the back of my radio if I got two amplifiers for 3 amplifiers all I have to do is just run a wire adapter off of one of the other of the RCA coming from the head unit that being said the other ones are there just kind of a backup or a spare in case you blow an RCA channel you have three other sets so that means you can run your sub off a high or a mid-range Jack coming from the head unit I believe that's what you're saying it's been awhile since I hooked up double or multiple amps I did it some years ago and I couldn't remember but I thought you just jump from one amp to another where it says in and out the out would be to your next amp and that's all you would need to get sound coming through your amplifier to your speakers I did that recently a day ago and I was getting a weird noise coming from the speaker so that probably explains that I don't jump to another amp off the previous yep I got to come directly from the head unit to get the right RCA frequency for each individual specific amp ?
Thats what I was just thinking about.
hey jake need help hooking stereo
Maybe I can help, message me on Facebook/Instagram JacobViral
thanks man this answered most of my questions. but i have just one question. now how do you use the bass knob to control two of more amps? is there such thing as a Y splitter for bass knobs too?
Rca bass knob through your main rca line near head unit in/out then splits later down so controls all signals.
i have questions about connecting two or more amps using a bass knob , does it affect sound quality or affect the strength of the volume?
@@ixrvalor0812 yes and no, will depend on the quality of the knob used as well as rca/connection quality. If no issues and high quality, should see minimal to no difference. It’s a big factor many use for more pros and little to no cons.
Wouldn't this splitter drop the quality and voltage of the signal a lot? Since there is so many outputs out of one RCA? Maybe better to use sound processor in this case?
Seen people have up to 8 amps and work just fine? I doubt that’s something to worry about but if it’s full sound quality then yes
@@JacobViral2 I’m still kinda lost lol how many y splitters and 4 channel rca cables would I need for 3 4 channel amps

Hi Question??
Sure whatsup maybe can assist. Feel free to message me on Facebook/Instagram JacobViral
@JacobViral2 I recently installed a passive line output converter for a Sub amplifier all great no issues. Now I want to install a second amplifier a 4channel I usually use an Lc2i for this purpose. My question is can I use my existing LOC and connect it to a new Rockville R7EQ that has sub out ,rear out and front rca output. Or should I still get the LC2I ..Thank you
@@marcovaldovinos5009 try before buying and it it works don’t , but I would think the additional device probably will help? I honestly use aftermarket radios always only so no experience with stock
@JacobViral2 thanks anyways
Could you get more repetitive? Fml.
if someone didn't figure this out on their own they shouldn't be any where near electronics. sorry
What about the power wires hook up
There is fuse block distributors like amzn.to/466WKbv that work for multiple power runs.
Hi.. I have a question…. If I run Distabution black .., can I also run my DSP ?
Yes a lot use DSP as well
When do I need to install an extra battery? I have 2 amps.
