sorry if this has been covered, but I have about 5 minutes of battery on my notebook so this is it.

just installed a D3 in a tc with some Infinity Components and now im getting an alternator whine.

should i?

1) buy a cheap noise isolation adapter?

2) find a better ground for the head unit and amp (the amp is definatly grounded to the chasis via large trunk bolt

3) grounding kit? could that help?

how about other ideas?

Check all your grounds

did you run your amp power wire and rca's down the same side of the car?

I'm getting the same whine from Alternator... Damn....

this sucks... someone grounded my RCA's but there is still some left...

im still getting alt. whine from my speakers..its really annoying my sony deck never had that problem..and my batteries are in the trunk and im using expensive rcas. Could it just be that a bigger ground lead is needed than the one supplied by the war harnest?
