Hey guys and gals. I have been reading all of the posts on the forum relating to installing a new head unit and I am completely confused and frustrated after reading over everyone's "thoughts" of how it should be done.

There seems to be some discrepancy about how to wire the power wires and the Amp outputs. I have seen conflicting pinout descriptions for the amp and have no idea which one to follow before beginning to cut wires. Is there anyway that the moderators can remove all of the bad info on topics like this so as to not confuse everyone?

Does anyone actually know how this should be done and do you have clear instructions on how to do it? I thought this would be a fun project to take on, but at this point I have my car completely torn apart and have no @#$%'ing idea if I am doing anything right. I guess I just need to pay someone several hundred dollars to rip out what I have done and install everything from scratch.

Thanks.

 

The chrysler schematics from Tech Authority are labeled wrong. Wire fronts to the front inputs on the power amp. The rears are jumpered to the fronts in the cable harness that goes from radio to amplifier - there are splices about mid-cable beneath the dash under passenger footwell. The rear channel from the amps are labeled in the schematics as "power" and "twisted pair speaker leads" - NOT! These are dual voice coil subwoofers. Leave the stock amp in there. Just "unsplice" the fronts from rears on the power amp inputs, so the front fader is my fronts and the rear fader is my subwoofer, which improves bass response. But, if you just wanna' new radio, it is OK to just connect speaker leads from front channels of new radio direct to the existing left/right leads on the stock connector and go to factory amp.


Brown: pin 8, is ground
Blue/dark green stripe: pin 5, turns on your amplifier as well as the amplified antenna
Red/dark green stripe: pin 4, is constant power
Pink/yellow stripe/dark green dots?: pin 7, is switched power aka accessory
Dark Green/White Stripe: pin 3 AT AMP, is for speed sense if you're installing a NAV unit


Here is where you have two options:

1) connect the regular speaker outputs (fronts probably best) from your new deck to the speaker inputs in the dash

2) Go into the passenger footwell, flip the carpet back, remove the styrofoam (just lifts out), unbolt the metal plate on the floor (this has the factory amp bolted to it..) and then solder on RCA ends to the speaker input wires...

Once you have the amp vilisible, you will see the harnesses that go to it...

Locate the one with "twisted pairs" of wires with the following colours:

Blue and Blue/Brown stripe
Yellow and Yellow/Violet stripe

There will be two pairs of each of these...


Next, unwrap the tape and follow the wires down the harness a little bit... On my car the wires were joined about 6 inches from the amp plug.

When you find this splice point, this is where you can cut the wires, and where you will attach your RCA ends...

If you are good with solder, Purchase some quality (4 total) RCA Female ends at your local stereo shop to solder on here, and buy two RCA cables to run from here to the back of your new deck (6 foot should be long enough, but 10 never hurts) ....

If you are not solder savvy, purchase a 20 foot RCA cable and cut it in the middle...This will also save you a couple of bucks...

NEXT:
Now that you have located and cut these wire pairs, you will begin with soldering...

Each Blue and Blue/Brown stripe pair and each Yellow and Yellow/Violet stripe pair represents one speaker. Which speaker or subwoofer, ??? you will figure that out after you solder on your RCA's, so don't worry about that...

Yellow is positive (the center pin on the RCA) and Yellow/Violet is negative (outer ring on RCA)

Blue is positive (the center pin on the RCA) and Blue/Brown is negative (outer ring on RCA)

Once you have all of these hooked up, tape up the unused / cut wires on the "deck side" , and plug your new deck in.

Next: guess and test method..

Hook up the newly soldered RCA's to your new deck ONE AT A TIME...With the deck on and playing some music...

This way you will be able to hook up the correct RCA's to the deck for the left front, right front, and non-fading/sub outputs..

And that's all there is to it....

Good Luck!
