I had recently replaced my amp with a better one, it worked fine for awhile but now whenever I am on the radio or if the volume is real low there is a lot of static, the subs are just bouncing up and down with no rhyme or reason. What could be causing this? I checked, the ground, power, sub cables, and preouts and they all look to be snugy secured. Any help would be appreciated.

 

If your amp power leads run close to your RCA leads you will get some interference. Try seperating all your leads.
