A3 speaker buzz with non-standard head unit installed
Guys,
I've recently replaced the standard Audi Chorus radio/cassette in my A3 with a Sony CD head unit which I had in my previous car. Since the Sony has been in, the 2 rear speakers give off an annoying buzz when the unit is powered on, even if the volume is on zero. Is there a known problem connecting 3rd party head units?
I'm using an Audioleads wiring harness PC9-401, and my Sony head unit is a CDX-MP70.
Thanks,
Gary

Sounds like you've got a ground loop problem. Run better ground to your head unit and the buzz should clear up. If not, try a ground loop isolator. Ten bucks at a stereo store.

I thought ground loop isolators were for RCA cables? And yes, you may want to drill yourself a new ground or find a bolt as close to the headunit as posible instead of using the brown audi ground.

I jsut got my 92 100-had a old cd player in it and only one speaker working, and that had the BUZZ going---found it much eaier to just run new wires to all speaker and buy new speakers..I bought some cheap kenwoods at best buy $110 total for front and rear--guess what they sound 100% better than I had for little $$$--there lound enough for me and sound good----just my 2 cents-----
