Just wondering where you guys grounded your amps in your FD. I have tried two spots, but both spots produce alot of alternator wine, which only gets worse if the engine fans kick in.

Yes, the power cables are ran far away from the rca cables, the only point that they are close to the rca cables are when they plug into the amplifier. Plus, they are the same exact rca cables that were in my g35, and I did not have alternator wine in that car. So I must be using a crappy ground point.

Also, did you use a different ground for your head unit?

 

Get yourself a ground loop isolator from Stinger. It will stop the noise
