XT stereo wiring question


Recommended Posts

OK... posted this on XT6.net, but so far I haven't received a definitive answer, just a "search the posts"... doing so is now why I have a problem.

 

When I search for information on the color codes for wiring the stereo there, I can only find 2 posts, and the information contained within is conflicting. About the only thing that the 2 posts agree on:

 

Black is ground.

 

Duh.

 

If anyone know which colors of wires are 12V Switched, 12V Constant, and Power Antenna, I'd appreciate it. I don't terribly need to know what color the speakers are, as I am going to run new wire to the speakers... but knowing it could help me narrow down the wires I need.

Looked at the wiring harnes.

 

Problem:

 

Lavender/yellow does not exist.

Green/white does exist, but it is the same gauge as the speaker wire. The ground and constant power wires appear larger than most of the wires, as do 3 more wires in the harness

(Yellow, Red, and a blue with a stripe color that I've forgotten).

 

I'm really starting to think that Subaru has been building their cars with whatever color wire they happened to have laying around, rather than what is ACTUALLY supposed to be there, because your information is the 3rd set of different wire color possibilities, and I'm not sure my car matches, so that means a possible 4th set of wire color possibilities.

 

MY BRAIN! (splode)

 

Edit: I suppose this is a bit much to ask, but I don't suppose you'd be willing to pull your HU out and find out what 1) position in the harness (clip side up, starting with the upper left as pin1 and counting all the way across the row to the right) AND 2) what COLOR of original wire the following wires COMING OUT OF your head unit are connected to:

 

Blue

Red

Yellow

Black

Thanks Tom! I cringed when I read EV's post :eek: Like I said before, if your still having probs I can scan the FSM. If it will help.

 

OK... it looks like I've got the main 4 wires figured out

 

Black = Ground, Blue-Yellow = 12v Switched, Green-White = power antenna, White = 12v Constant.

 

Verified this through use of a multimeter.

 

Picked up two new sets of speakers, and ran completely new wire from both sets to eliminate the shared ground (and the stock speaker wiring completely).

 

Everything is wired, but I get a whole lot of nothing when I turn the car to ACC.

 

Power antenna goes up, but I cannot get the HU to power up, and there is a soft tap about once a second through the front speakers. Disconnecting the harness from the HU lowers the antenna, and the tap goes away.

 

testing the wiring at the HU harness, I find that everything is wired correctly there, but nothing doing.

 

This deck has been sitting in my office for 2 years or so, and was pulled from a friend's car when it was put into my office... I'm thinking that the deck is dead. Ideas?

 

Edit: I wouldn't imagine this would have an effect on the performance of the head unit, but in order to make the work of hard-wiring easier, I took the main 4 wires and butt-spliced them to sections of 16 AWG wire (it was what I had laying around). This allowed me to have enough room to strip and crimp outside of the dash. This shouldn't be causing any problems, right? Especially since voltages are correct at the HU harness?

Just got back in the house from checking the wiring. Brr, it be a little chilly, and there's frost on the car.

You got the wiring correct according to mine, so it sounds like the HU done gave up the ghost.

 

I have mine wired according to the pin-out below, used the stock wires for the fronts as they are seperate ground, the rears I ran new twin-axial cable just 'cause it was free from work. :) PO had ran the RCA cables for the amp, just need to get the rest of it, someday....

 

Here's the pin-out of the car side of the connection for the radio, just for referance. Release tab is up, going from left to right;

 

Top row;

Blue/yellow = switched +,

Red = dimmer (headlights on),

White/Red = Right Front +,

(release tab) ,

Blue/Black = Right Front -,

White/Blue = Right Rear +,

White = Battery +

 

Bottom row;

Black = Battery -,

Red/Black = ? (didn't find that one),

Yellow = Left Front +,

Green/White + Power antenna,

Blue/Red = Left Front -,

Yellow/White = Left Rear +

Picked up a new HU before going to work this morning. Will wire it in at lunch, already have the butt connectors on the HU harness. Just need to snip, strip, and splice the wires in the dash again.

 

Should be a decent sound setup.. Found a set of Kenwood 160W 6.5's that fit the stock rear deck location EXACTLY (screw holes, basket, the whole 9 yards... even the stock grilles fit over them). I had a dead ground on the R side, so I couldn't trust the stock wiring. Didn't want to run new wires to the doors, so I've got some 6.5" boxes with a set of Dual 140W speakers... they are such a perfect fit, that they wedge in and can't be pulled out or move at all without sliding the seats forward to "midget" position.

I had thoughts of running new wire for the fronts, but that looked to be a real PITA job, glad the stock wires were still in good shape. Got a Pioneer HU with 180's in the doors, 200's in the rear shelf. Boy was doing the rears fun!!!!! 6'-3" 225 lbs, don't fit in the backseat area real easy. Was wanting to put the covers on that came with the speakers, but changed my mind. No sense in drawing attention to it, other than blasting out some ZZ Top that is.........

 

Hope the new HU works for you. Like I said, wiring sounded right...

Yup, works great... though the initial volume is lower than the Kia (which has the same deck), I'm able to get more control and more overall noise out of this system.

 

Pretty impressive, since the Kia has Infinity's all the way around.

I know what you mean. Got the same HU in my '95 Dodge Ram running the factory speakers. It just plain JAMS!!!! More than what the systen in the XT does. Wife says she can here me coming around the corner. Some tunes just have to be cranked, KnowhatImean,Verne?
