Re: Alternator whine on RADIO

     Any good car audio center should have noise suppressers which you can 
     wire into your power leads.  $12.00 or so.  My VW Jetta did the same 
     thing.

     This ones for the Audiophiles in the group:
     
     Just installed an aftermarket radio in my 86 5KCSTQ. I used the 
     factory speakers and hooked directly to the factory wiring for them 
     including the rears with the Audi amp.
     
     I get a tremendous amount of engine speed dependent alternater whine 
     through the unit.  I tried powering and grounding the unit directly at 
     the battery...no change.  I installed a quality noise supressor in 
     line with the power from the battery....no change.  I tried replacing 
     the altenator with a rebuilt Bosch unit....no change.
     
     In a last attempt I removed the belt to see what the difference 
     was...much better (no more high pitched whine) with a hint of engine 
     spark noticable (I think I need new plug wires anyway. Next week).
     
     The factory radio had a bit of whine also before I removed it but due 
     to the low power amp it was more tolerable.
     
     ANY ideas??  I've been tuneless for a month and am going crazy:-s
     
     
     thanks!!
