Thats alternator noise. You may want to check into your ground of your amp.
Poor ground there can make this worse. Also if you run the rca's along side the fuel pump harness you can run into this too. It runs along the driver side.
Verify power ground, and remote to the amp are in good condiotn. ( use a DMM)
As far as the a/c, does it cycle the compressor or no?
