couple things, running a 425 wat amp for my rear Infinity 6x9's and twin MTX 8's. using 10 awg wire for power/ground and 20 awg for remote. I have a buzz that coincides w/ engine rpm. Grounded under body by tailgate. Not big enough wire? Bad ground location? Also can't run too much electrical with this setup ( ac/heat fan, lights ) big drop in volts. Lights dim gauges flip out.

sounds like ground, or RCA's

change your ground and do the BIG 3 under the hood and make sure your are not running your power wire and rca's down the same side if so change that to good luck

 

[drowndindreams]

most likely your RCA cables. are they run on the opposite side of the power wire? are they thick?

If you try all of the above and it doesn't stop the buzzing you can pick up a "ground loop isolator" at Radio shack for about $15. That has done the trick for me in the past when nothing else worked.

PAC SNI1 ground loop isolater. I have 3 of these in my other car (using active crossover) They were the only thing I could find to isolate the sound of my amp rack's cooling fans.
