Also check all your grounding points.

check your amplifier power connections.

Check the phase adjustment on your deck. I was having this problem, and it was a simple adjustment on my deck. I was running a jvc double din DVD. It took a little fiddling.

I'd second the call to have your battery checked.

Also check the power and ground feeds to the bass amp. I had a similar issue years ago that turned out to be caused by a melted inline fuse-holder on the amp's power feed.
