Here is what i'm running: zapco studio 100x-MB quart pwd 254 sub; mbquart psd 213 components-zapco studio 100;kenwood head excelon head unit and 6 disk changer. Anyway, I've got this buzzing sound ever since I hooked up the quarts in the front. I also get a little alternator whine. The sound is constant, and does not increase with increased volume. Also, the sound is there only when the car is one, completely clean when car is off. What i've done for a quick fix is just turn down the gain on my amp, and put the NF the whole way up to the fronts. Its still there, but not as bad. Anyway, i've sanded all my grounds, for both amps, and the ground stiffener for the battery(4 gauge). I'm running 4 guage wire, with 8 going into the amps. Ground length for the amps is like 6-8 inches(8 guage). I have racked my brain and can't seem to find whats wrong. It seems like a ground problem...but i checked everything. Also, i checked the rca's and its not that. So I'm asking all the experts out there....what the heck did i do wrong?
