Wiring diagram
 

Does anyone know where I can find a wiring diagram for a JVC KD-APD89 headunit? Wanting to know what wires are what on the harness.

Im not going to garentee this but im 99% sure this is right. all JCVs ive owned were lil this.

Memory (+12v Constant) Yellow
Ignition (+12v Switched) Red
Ground (-) Black
Power Antenna Blue
Amplifier Turn-on Blue/White

Right Front (+) Gray
Right Front (-) Gray/Black
Left Front (+) White
Left Front (-) White/Black
Right Rear (+) Violet
Right Rear (-) Violet/Black
Left Rear (+) Green
Left Rear (-) Green/Black

EVERY aftermarket headunit is like this

O ok lol. I think pioneer are just a little different tho

:)...

Sweet thanks man!

One more question, I can run two amps off the same amp turn on wire right?

yes just run a jumper wire from 1 amp to the other

Like connect it amp to amp or just the wires on the back of the headunit?

run a remote wire from the head unit to 1 of the amps and then where you connect it to the amp run a jumper from there to the other amp if they are both close or you can run two off the headunit either way it works just easier the other way ... guessing you're running a 4 channel for your mids/highs?

What I'm wanting to do is get a mono amp to run my sub off of and use the amp I have now to hook up to the speakers.

why? is it not loud enough for you now? if so is it the sub or the mids/highs that aren't loud enough. what amp do you have now? does your headunit have more than 1 set of rca's?

No lol I want it louder :D I just talked to an "expert" from sonix electronics and got it all figured out. I got a new project but don't want to give it away yet... I'll make a new thread on it soon. Thanks for the help Matt.

if you're looking to get louder i'd start at building another box ... one of the cheaper upgrades you can do .. the box for the sub is atleast 60% of the sound

Amping you mids and highs will give you a much more clearer sound just make sure you have cross overs of that the mids and highs have built in cross overs first. Mids and highs in my tahoe are amps with a 1000watts and my subs are being pushed with 7500watts its hellacious

not necessarily alot of lower end amps just make the speakers louder and don't help with the sound quality the better amps have alot better components and that makes a big difference and also better xovers

oh really? what amps do you have? and how many batteries?

sorry i just seen this post matt. i had a AQ 3500.1 and Fi BTL 15s. ungraded ault, and 6 batts

thought you said you had 7500 watts ...

an AQ 3500.1 amp will throw up to 15000 with the right voltage. at 18v 7500watts

i guess this is where you read that .. at 18v it might be 7500 watts but you aren't running an 18 volt system you're running a 12v the best electrical systems could push 14.4 but i doubt that you'd be able to sustain that bc that amp is a monster so you're only seeing 4k max bc ur probably actually at 12 volts or lower when the system is up

the 15000 watts rating is for strapping a pair of 2 of them together not just 1

o I see. my buddy was the one telling me it was putting that much out and what it was rated for he said it was on audioques website on the amps specs.

guess i was wrong but it definatly was a beast and I really miss not owning it anymore

yeah those amps are nice i've had some monster dd amps as well - their sister company

DD are sweet. my buddy (guy that i bought the AQ from) is running two 12" DDs.

have you heard on jbl?? if so are the a good sounding brand?
