could be a ground issue, could be a few things though, as you can read in my post "it never ends lol" Does the buzz get worse when you hit the gas? do you get sound and buzz, or just buzz?

usually when it gets worse with rmp's its a bad ground, go back and clean up all your grounds with some sandpaper and some compressed air. If that doesnt do the trick did you run your rca's down the same side as the power cable? if so move the rca's to the passanger side. Also check the gain on the amp make sure its not higher then your EQ settings on your HU this will give a static sound when the sound is off but the radio is on. If none of this cures your issues come back and let me know these issues are tricky since there are so many variables. Also make sure you use quality rca cables.

Cheaper amps make more noise; adding a cap might work...

As was mentioned above, grounds are critical. Look over 'thewiskah's' post on this section.

Other sources are the caps on the coilpacks, bad plug wires, dirty battery connections...

try disconnecting the input to the amp, and see if the noise is still there. that's where I'd start.
