Need some help
 

Ok, so last week my stock HU took a crap on me. I went out and got a JVC g720 I picked up the stock wiring harness adapter as well. I wired everything up and I am getting no sound. The HU powers up and works like it should I can throw cds in and hear them spinning and I can tune in radio staions and Im getting a full signal, however there is no sound from the speakers.

The stock system is a Bose. I was searching around in some old threads and saw someone mention if you had a bose system you had to rewire everything. I hope this isnt the case as I have an 8 hour road trip coming up and I dont have time to rewire the whole system.

In some cases, old speaker systems are not compadable with new HU's. However im not sure this is the reason in your case. I'd check all the obvious things first. Grounds, bad wiring, bad hookups... etc.

The ground is solid, and the wiring is as it should be. I matched up the HU wiring with the stock harness adapter. (i have checked it a dozen times since then). I tried some other speakers I had laying around on the new HU and it is putting out sound as it should be. I tried using a different stereo to get any of the stock speakers to work and they just wont for some reason. Do I have to hook up an amp to get these things working or what?

It already has a stock amp, look under the 5th speaker in the rear hatch.

Just sounds like those speakers/wiring isnt going to work on a new HU. I dunno from experience though, when I did it, I swapped all the speakers and wiring out too.

Hmm the wiring harness adapter doesn't have any wires labeled for an amp. The harness says it's for a 93-96 camaro with bose. Although now that you mention it the speaker in the rear is in a large box with 4 wires coming out of it instead of the 2 it would need to power the speaker. Which probably means the amp is in that box.

So I guess I would need to power that amp before I could get any of the speakers working? (yes I'm still looking for a way to get out of rewiring the system. :rolleyes: )

I honestly dont know. Im just spitballing here. I wish Arch was around, hes the electronics mastermind of this site.

Isn't it great when you take on what you think is going to be a small project and it blows up in your face? :banghead:

That has happened with about 90% of the things i've done with my camaro :banghead: So I know how you feel.

Just learned something else interesting, #1 the speaker covers for the speakers in the back seat area are very easy to break (******). #2 There weren't any speakers behind them. Its a 3 speaker system. Two in the doors and the one in the back hatch.

Thats odd. Its typically a 4 or 5 speaker system. I assume this car was owned by someone before you.

I got it from the original owner. It had sound proofing crap over the speaker holes so it looks like it came that way from the factory.

Early years bose was a 3 speaker setup. In the gm harness there should be a power antenna wire hook this to your radios remote turn on and bam you will have sound

That did indeed work. There is a slight buzz in the speakers but since I don't have time to screw with it before my road trip it will work a hell of a lot better than not having any music. Thanks.

the ground at your radio make sure its solid even try unhooking the ground from the harness and goin to like osme metal back there. If you still have noise there is a way to fix this. Can you confirm for me that your volume knob is very sensitive?

Yes the volume is sensitive.
