where is your power wire? Do you have your rca's next to it? i had the same issues with my rca's and power wire being together.

you need a better ground. Make sure it's bare metal and if your in a trunk car use the shock tower bolt.

in all unibody trunk cars it should be in that general area. right in board from your wheel.

might want to try an outside source for your amps input just to make sure the problem is the amp. Did you scrape the paint off and ground to bare metal?

Can you take pics of trunk? You may have to pull the carpet out to get to it too. Also I had to rerun my rcas a different route one time cause I was getting interference from somewhere. But once I moved them it was fine.
