Car audio problems - Audi TT
I have a problem with my car audio system and it is driving me nuts. Its been going on for over 2 years now and I have not find a way to fix it. My car dealer does not know the real problem and so they suggest to change the entire sound system including re-wiring which costs a fortune.
To begin with, here are the specs of the car model and sound system:
Car: Audi TT - Roadster (2002 model)
Sound system: Bose (Audi Concert) with CD player and 6 disc changer
Here is the problem:
Basically what happens is that the sound goes off on its own. I turn the car on and turn the radio on, it works fine, after a few minutes, I start to hear some sort of static sound from the speakers, its even kind of the sound of something burning, like little crackles, it gets louder and louder and then the sound goes off, muted. At the exact time as the sound goes off I hear a clicking sound from behind the passenger seat (which is where the Amp is). Sometimes the clicking sound goes on about 3 times with double clicks ever time.
At this point the radio stays on, all the functions work fine but there is no sound. Sometimes if I turn off the car and turn it back on, the sound comes back but within minutes the problem occurs again.
What I have tried so far:
I got another amp, exactly like mine from another TT, replaced mine with it and still had the same problem.
I got another radio (Audi Concert) exactly like mine and still had the same problem.
I tried replacing both the radio console and the amp and still had the same problem.
This is driving me crazy, I have a great sound system which I cannot enjoy! The Audi dealer tells me they dont know what exactly the problem is, but they can fix it by changing the radio, the amp, all 9 speakers and all the wires for those and this costs way too much.
I am certain it must be an electrical problem, maybe bad ground? A car electrician once plugged a laptop into the computer board of the car and told me I have electrical problems, something about voltage not being stable or such. I had him check my electrical voltage because the internal lights of the car (button lights and dashboard) seems to not be stable, then dim on their own, they go strong and weak...
Can anyone help?
