- How I connected amps to my OEM head unit.
I had to edit a lot out to keep within a certain time frame. If you have any questions, please feel free to ask!
Also, I had to edit this on my iPhone and couldn't provide all the links. I'll put them in the comments.
The explanation on the harnesses and wiring has been super helpful. Thanks.
Holy shit!!! You gave me the key to wire anything I want ! Thanks a whole lot !!
So I'm only using one set of RCA cabels from the front speakers to the amplifier for my sub. Haven't installed it yet. Should that work? Also how many watts are you running? Have you had any issues with your alternator or battery? And I do have some questions about the bass knob and cup holder lights.
Spencer Bennion
I would use the rear output instead of the front. Both will do the job, but your subs will most likely be in the trunk, so this would be more natural.
I have replaced my battery with comparable Interstate battery, OEM alternator.
I have roughly 2400 watts available, between the two amps.
As far as the cup holder lights, they were purchased from accentleds.com
You would need 2 sizes, 1@ 2-1/2” & 1@ 2-5/8”.
The bass knob is from Kicker which is proprietary to their amplifiers. I took it apart and mounted the guts inside the dummy plug next to the trac control/vsc button.
Follow me on Instagram, I can help you better there. @cdenton9
Is there anybody that sells this already made or a version of it for 2015 model or do you have more made for sale ??
Noob question. This will work if I’m only planning on using the front and back Rca hooked into my amp right? I’ll have everything hooked up like you have it, but everything but the two rcas will be hanging.
HorizonsHere are you coming off your amplifier straight to your speakers? If so, you’ll have at least 8 wires not in use on the reverse set of harness.
If your planning to reuse the factory wiring to your speakers, you’ll need to make the connections.
Yeah I'm planning on coming off my amp to the head unit with the 2 sets of RCA's and connect to the harness rca adapter you have in the video. I purchased what I need from the 3 links you left.
hey friend, I have a question, even after installing this harness it worked even with your original car reverse camera, or you need another type of harness
rickaz1093 had to watch the video again to answer your question. The OEM camera plugs into the Maestro. The Maestro harness provides a video output that you’ll plug into your aftermarket head unit.
I know this is an older video, but did you reply the stock speaker wiring for the back and door speakers? I've heard the factory speaker wiring isn't good on most cars and was wondering if I should plan on rewiring all that shit while upgrading my speakers.
Adam Yarris i reused the factory wiring. It’s good stuff. 16 gauge stranded copper, probably ofc. I did eventually run new wires to the rear deck speakers though. Only because of the length, 3 feet versus 15 feet. And I was putting about 80 watts through the factory wiring.
@@suprola7961 Huh, I wasn't aware of that, thanks for your response! I got the impression all factory wire was crap, but then again I know next to nothing. Great video btw, I couldn't find much else about this in such a clear manner.
For my set up i plan on using the stock speakers and only adding a single amp to power subs in my trunk. Does this set up allow for this?
Were u able to figure it out?
@@mafitron Fr lol I need to knwo
i’m trying to hook up and amp to the factory audio system,using a line output converter or is there any other way? i don’t want to hook up speaker with the amp..what kind of harness do i need?
Salman Asghar it sort of depends on what amp you’re going to use. some amps like kicker, have line level input or high-level input. In that case, you don’t even need LOC’s. The factory radio doesn’t put out much voltage, and probably not enough to damage whatever amp you use.
I would convert my speaker outputs from the radio to straight RCA’s, run those to your amps and then bring the speaker outputs back from the amp.
Basically letting your amps drive everything and your HU driving only the amps.
I hope this all makes sense.
So using this harness you just run the RCA cables to the back amps and then run speaker wires back up to the harness? Did you split the RCA in the back to run the sub?
+spendous
Yeah. I ran front and rear RCA’s to the amps. The rear channel goes into a 2 channel that has pass through and that jumps to the rear channel of my 4 channel amp. The front channel just goes to the 4 channel amp.
I used speed wire or 9 wire to send the speaker outputs back to the factory harness.
Just this weekend I eliminated the rear speaker wiring going back and forth and ran 16 gauge off the amps straight to the rear speakers.
Is it possible to wire it with only 2 RCAs going to the amp? I bought everything you linked but my amp only has 4 RCA slots, 2 Input and 2 Pass Thru
Where did you hook up the lights for the radio to work ? Where it says audio and all ?
Scbba if I understand your question correctly, the lighting circuit is part of the radio.
what is all of the wires called thats needed to use a 2019 corolla factory radio for a subwoofer? I cannot open the links that you provided
Reese You’ll have to search for these online, part numbers :TWH950 & TWH951.
I can’t get the links to open either, except for the Kicker link.
I have a 2015 toyota Corolla and I need to figure out which wires are + & - for the rear. The factory wiring is chopped so I can't use the speaker trick
Did you ever figure out the colour code? Need to install convertor to a corolla IM
Are u running a stock alternator...if not what is it. Would like to run up to 2500w in my carolla
Matthew Love
I’m still on the OEM alternator but I’ve been considering an “upgrade” or a 2nd battery. I’m up to 3000 watts available but can’t crank it that high. Lights start pulsing and bass will drop out.
I haven’t even added the larger wire to the OEM alternator yet.
Do you happen to have a wiring diagram for the 2014 Corolla pin connector? I am trying to find the 12V constant wire & 12V accessory wire for my LOC & almost every wiring diagram i find contradicts the other
Aftr Shock are you talking about the factory harness or the aftermarket piece used for connecting to an aftermarket head unit?
Chris Denton factory harness, in the back of the factory oem radio
Aftr Shock I do not know the pin out off hand. I would have to pull my head unit out to get this information. Check the forums, corollaforum.com or toyotanation.com , I think I’ve seen it listed there before.
Is this a S type corolla can you tell me if your left fog lamp is out of place I have the same car????! And have seen all the fog lamps on the driver side out of wack like out of place the right side in the passenger fog lamp is in place and sits well in tacked
Game Winner I’ve never had any issues with my fog lights. Mine was an LE. I replaced the fog lights with complete LED units from AuerAutomotive.com
Hey man! if I want to hook up just a pair of subwoofers, can I just T from any speaker using the cables you used?
Himmler Andaluz Aguilar
You can but I doubt you will get any base from it.
Chris Denton do you know if theres a way to get speaker signal so I can put the kicker rca while keeping the 4 stock speakers. Btw I do have amp subw and all that stuff.
@@haaguilarJust T into your rear speakers and go straight into the amp if it has speaker level inputs or get a LOC if it needs RCA. Unless you have a 5ch amp or a signal processor then that's as good as you're gonna get.
Hey so if I just want to connect my stock radio to a all-in-one amp+sub and don’t want to add any other speakers do I wire it the same? In essence can what you created be used as a splitter so that I can have the stock stereo output to the speakers as normal and also to my sub?
My sub has high level and low level input.
Thanks very much for the video!
Taiga Hashimoto
Yes, you can tap whichever channel you want to use with an RCA pigtail and then run signals to your amp setup.
Personally I would still make my own harness to avoid tapping the OEM wiring. Adding stuff creates a cascade effect that never ends 😆
Hey I have a 2016 I'm trying to build that harness and I have the rca cables coming off the head unit only part I'm confused at the point when you said the speaker came right off the amp for the front and rear left/right
Adam Johnson once you’ve made the T harness, you are no longer using the outputs off the headunit to drive the speakers. Your speakers will need to be connected to a 4-channel amp. The RCA’s that are now coming off of the headunit will control your front/rear/left/right fader. But the speakers will be powered from the amplifier at this point. Does this help?
@@suprola7961 yes it does exactly what I figured just wanted to make sure I was on the right page thank you for the reply
hey boss i dont really know what the cords im looking for are called i tried ur links below but 2/3 dont work could u plz point me in the right direction

So if I want to get an amplifier, sub woofer, and new speakers but still use my stock radio head what wire harness would I need to buy in order to not tap into the OEM wires? Please I was trying to get that part but got super confused 😭.
The next comment down are the links for the harnesses, if they’re still available.
@@suprola7961 I have the website open but which one would I choose? Sorry I'm a total noob but need your help please. Do i get this wiring harness "Toyota Corolla to Install Stereo" or "Toyota Corolla Wiring Harness to Connect Factory Stereo"? Also thanks for getting back to me quickly I appreciate you 🙌.
@@suprola7961 i was able to access the website. Now I just need help to pick please.

@@vegaf2011 I posted another link. You need both, so you don’t have to cut any factory wiring.
Hi One Question i did wired everything but i lost the reverse camera function. I put reverse and it doesn’t displays the backup camera. What could be the problem, is it a bad connection?
Joseph Rodriguez
Did you install the Maestro also?
No I just installed the harness for the rca front and rear as you added on the discription. Unless i disconnected by mistake other harness since i didn’t removed the radio.
Joseph Rodriguez
Nvm, I was thinking you replaced your HU. Could be that something is unplugged.
Yes It probably could be that, because i doble checked and the harness itself doesn’t involves the backup camera.
Can it be done only using one amp cause the loc doesn’t work at all
Yep
Hey when you say you sent the signal back to the amp what signal from where im trying to do exactly this and i dont have the 4 extra speaker wire to send signal back with cause i tapped the speaker to rca on those already
I pull speed wire from the amps to the back of the radio.

@@suprola7961 oh ok i understand that now when you did the rca adapter "kicker kisl" to the harness you had 1 set to front left right+&- then on other adapter same thing what were the open spots on the adapter that you sent the signal back to amp inputs?
Basically, you’re converting the headunit outputs to RCA and running them to the amp(s) then using speed wire to return to the headunit, where you intercept the other side of the wiring you converted (goes out to speakers)
Original links are now broken. Do you have updated links?
Since it’s been a couple years... I don’t.
I would have to research everything all over again.
What exactly are you looking for? I can help some.
You don't want too much voltage going through the RCA for the amp. You can do it this way for one subwoofer amp.

How did you bypass the tweeter in the front to add your speakers to a amp ?
Scbba on the stock tweeter connector, you have 2 positives and 2 negatives. One pair of +/- comes from the head unit, the other pair goes to your bottom door speaker. I just taped wire in between the positives and negatives, to complete the circuit down to the bottom speaker. Then I used the tweeter wiring that came with my component speakers. Does that make sense?
Chris Denton sorta but not really lol
Do you need the run the speaker level up or can you just run 3 rcas back ? 2 for the 4 channel and 1 back to the mono block ?
Scbba if your converting from speaker level output, off the radio, you can just run the 2 or 3 pairs of RCA’s back to the amp depending on your radio. Are you using the factory radio?
If your using LOC’s (line output converters) same thing depending on your particular setup. Some LOC’s use auxiliary power. What amps do you have?
How are you getting signal to your mono amp?
Chris Denton I have a loc for my mono block that I'm running off the rear channels now. I am running the skar 60.4 with tx 6x9 and the sx componets upfront. And I am adding a skar to 1500.1 on a pair of skar sdr 10s in a 4th. My 60.4 has the high level input on it I didn't know if I could use that with the wiring harness you show in your video or not but if I am not mistaken you will get a cleaner signal with the rcas. Yes I am using the factory headunit if I wasn't I wouldn't have all these issues lol I would just bypass all this
I got all this hooked up and my fronts are nothing but static and my rears are clean what could be the issues
Scbba I remember having this problem too. But can’t remember how I fixed it. Play with the settings on the amp. Did you use LOC’s?
Chris Denton only for my subs
Your using the kicker rca converter cables right? Did you meter the polarity before you spliced them in?
No I used the reverse harness for them and I have them ran to the high input of my 4 channel and my loc converter ran to my subs
Scbba, try disconnection your amp turn on wire.

Geez that’s a lot of wires
What spoiler is that ?
Derrick Somsanit it’s the type Z by Mapisa International Group / MPS Aeroparts.
What size fuse in fuse box by amp?
Too many variables to consider. Wire size, amplifier output, distance from battery, etc.
Need more specifics to answer your question.
@@suprola7961 ruclips.net/video/HrXBIQ5c0c0/видео.html
Wheres the amp located in the car??
I kept upgrading the system until I traded the car in. In the end, I had two amps screwed to the subwoofer box in the trunk. But at one point, I had a small 4 channel amp under the dash.
It really doesn’t matter where you put them, as long as there is adequate cooling. A lot of people mount them under the seats, but that’s not ideal since there is ducting under there.
The back side of the rear seats is a good spot, if you know what you’re doing.
@@suprola7961 thank u just trying to get new speakers my stock ones are blown and a sub hooked up asap
Does this car come with a factory amp??
Audiofilio nope
Chris Denton really ? That’s pretty cool, I mean in the idea it makes it easier to add your own system by just adding your own and not worrying about disconnecting the factory or removing it/bypassing it! I would assume it’s only the camrys that have one then right? Thanks for responding!
What wiring harness
What wires in harness you use ?

This is good but even better if you just get an amp with high level inputs. Then you dont have to fuck around with converting to RCA, you just run speaker wire to your amp and back up. Not sure why you make cutting the factory wiring sound like such a bigass deal. Just cut the speaker wires and reconnect them to your amp inputs/outputs and you dont need to buy a bunch of silly harnesses and find room to cram 2 feet of extra shit behind your dash.
