= ground loop, most likely. When the truck is running?- What noise and conditions?
Change the ground on your amp, and or ground the outer portion of one of your RCA cables directly to the vehicle ground; if it's a ground loop.
Thanks Antman! I'm not really sure what happened...I tighted up all the cables behind the amp and behind the head unit and now the amp isn't making any noises anymore? Hopefully it stays like that!
