[QUOTE="onecoolee, post: 3621354, member: 583404"] try turning your gains down too... when you have this so called "synthetic" noise, it is being generated by the DC components in your vehicle (due to DC switching on and off). USually this can be avoided by making sure that your amp is not amplifying a crappy signal. Making sure that your RCAs are carefully routed away from compujters and away from most stuff under your dash. Plus, use good RCA cables too... If you are using a factory headunit, which always has low signal level outputs, the problem you are experiencing will most likely always be there... factory HUs ****, and don't interface well to aftermarket stereo equipment. If you are using an aftermarket HU, in your basic, Headunit/amplifier configuration, as long as your gains on the amp aren't set too high, you should have no noise. [/QUOTE]
