stereo install help

[rsmith85]

Hey guys, new to the forum and after searching I guess this would be the best place to ask.

Today I installed an eclipse deck, checked and made sure all the speakers worked. Hours later I installed my alpine amp and rockford sub. As soon as I turned the ignition the only thing that would work was the sub. I am now getting no sound from any of the speakers.

I pulled the deck back out and found one of the wires from the wiring harness to the deck wires came out of the crimp connector. I reconnected it and found another, that one was also reconnected.

I checked all other wires and found nothing. I cannot figure out what is going on, any help would be appreciated.

Make sure your Internal amp on your headunit is turned on

 

[rsmith85]

I went through every option available on the HU and was unable to find any way to turn on or off the internal amp. Model 8443. It was bought in 2003. The only thing I could find that on the right rear corner you can see circuit board and I cant tell if it was trimmed, or if a corner was broken off.

I reinstalled the factory unit and all the speakers work fine. I'm guessing its something wrong with the HU itself.

This may be very vague,but you have to make sure your factory amp is wired to turn on when your headunit turns on

You have to make sure the orange wire is wired to a switch source,so when the h/u turns on your factory amp behind your glove compartment turns on

Radio 12v orange + radio harness
Radio Ground black - radio harness
Radio Ignition dk. green + radio harness
Radio Illumination brown + radio harness
Factory Amp Turn-on orange + radio harness
Notes: The amplifier is behind the glove box.
Power Antenna N/A
LF Speaker +/- tan - gray +,- radio harness
RF Speaker +/- lt. green - dk. green +,- radio harness
LR Speaker +/- brown - yellow +,- radio harness
RR Speaker +/- dk. blue - lt. blue +,- radio harness

I checked that, it is listed as "dimmer" on the harness. The speakers were working earlier today when I installed the HU. Later, when I installed the remote, RCA's, and amp the speakers stopped working. I reinstalled the stock unit and the speakers worked. I haven't found a spare aftermarket HU to test the speakers.

It's just weird that it worked prior to installing the amp and sub....

Thanks for the help, I can't figure this out, and seeing your sig I'm guessing you're good with this kinda stuff. If you can think of anything else please let me know.

I turned the volume up all the way and had the music coming from the speakers but it was really quiet. If I attach the orange wire to a power source it makes the beep noise when your lights are still on. What way could I wire that so it turns the amp on?

Right now I have no idea how to wire it, and I am wondering how I could get sound coming from the speakers prior to installing the amp and sub...

 

[Riff Raff]

You MUST hook up the remote to the pink wire on the flat harness. If you dont, no sound.

Use your blue remote turn-on wire from the deck and connect it to the pink wire on the smaller factory secondary harness.

it's the pink wire that turns on the fact.amp not orange

 

[rsmith85]

awesome, that is what I was wondering. I went to a car audio place today and he was talking about the orange wire. Im glad I checked this first. Thanks again.

 

[rsmith85]

Maybe this will help, its an 02 Yukon and on the rear of the factory deck it has one big harness and another small harness to the left of it, next to the antenna. Everything I have looked at says it does not have an ext. amp, which I was able to locate behind the glove box. I also have a fuse for the amp in the fuse panel under the hood.

I tried using the remote turn on and plugged it into the pink wire, no more sound than before. The audio installer said that if the remote doesn't work, to take the power wires(red on harness) and put a 5 amp fuse inline and attach it to the orange wire, he believed it to power the ext. amp. Let me know if this sounds right

Are you useig factory amp also? I am hveing similar problems i got the speakers to work but i put in another amp of my own and cant get it to work it turns on but thts it i put it on the bench and it works. So you might be haveing a power problem like me not enough power to run the other amps. I cannot figure out how or why it wont push the sub, it works fine in my other truck

If you have ANY of the speaker wires crossed, or grounded out, then it will shut off ALL of the speakers. Check all your speaker connection very carefully. If you have a multimeter, check to see if any are grounded out.

 

[rsmith85]

Okay... It still isn't working. I don't know if you guys have the same but I have two harnesses in the back of the stock unit. Further up those harnesses is another harness with 4 wires. That also has a pink wire. I wired the remote to that pink *4 wire harness* and also the harness that attaches to the stock unit... Nothing.... I didn't wire each at the same time, each was done separately.

Is there something I'm missing, I don't know what the hell else to do besides pay an audio place way too much money to figure it out.

So the problem is still that only the aftermarket amp is turning on, while the aftermarket headunit is not coming on with the ignition on 12v? if you have a bit of 16-18 awg wiring and some patience, rip out the knee bolster and dash clip and behind the knee bolster bracket should be atleast 2 orange wires, about 16 awg. disconnect batt, gently remove a tiny bit of the insulation from either, ( i used the one deeper in the dash, but both are an ignition on 12v,), just enough to temporarily attach a jumper wire , run that to the remote on wire coming out of the aftermarket wiring harness, this should show if its the deck or something more serious.
wouldnt hurt to double check with a volt meter (set to 40) to make sure your orange wires are working properly by probing the red voltmeter lead to the orange connection of the wire and the steel bracket behind the knee bolster provides a solid enough ground, and turn the ign to acc and you should get around 12 with it on and 0 with it off

 

[rsmith85]

the aftermarket head unit powers up, and everything works. I just get no sound from the speakers around the normal volume, I have to max the volume to get some faint sound coming from the speakers. I checked all the fuses, all fine, I even replaced them to make sure.

I have used a voltmeter to check to make sure everything is getting power, which it is. I don't know why it is not activating the amp so the speakers get louder.

 

[MASS-HOE'Z71]

Well thats just strange, it would make atleast a little sense if you had a factory amp which probably wouldnt cooperate with an aftermarket hu but speaker wires basically just run from the speakers to the hu without much interuption. And without any fuses blown and a working hu, it might be time to grab a spool of some good speaker wire and a cable snake Nd by pass the factory speaker wiring just to ensure no issues, wouldnt be a bad time to replace the speakers if you were planning on it.
Maybe not what you wanted to hear but a morning of wiring isnt to bad to ensure you wont have future problems

 

[rsmith85]

yea this was always going to be my end all, but I was trying to keep everything together and fix the issue. Thanks for all the help, it is appreciated, looks like I will be running some speaker wires.

 

[rsmith85]

Update: After all the research saying that the 02 did not have an external factory amp or a stock sub. Mine has both. I never noticed it til I would loading something in the back, but there is the stock sub sitting on the left hand side.

I haven't tried anything else with the system since my last post. Would the stock sub have anything to do with the aftermarket HU having to be maxed to get little sound into the speakers?

You MUST hook up the remote to the pink wire on the flat harness. If you dont, no sound.

it's the pink wire that turns on the fact.amp not orange

Thanks so much for taking the time to post this very important piece of info. Was in the process of installing a new JVC headunit and ran into the "unit turns on but no sound" issue. Jumpered the blue wire for "pwr antenna" to the now "unused" flat secondary connector's pink wire and, voila!, sound!!!
Much thanks, , ron
