How do I get rid of a humming noise coming from my subwoofer?

Question

I have checked everything from my ground to new rca cables. The humming stops when i unhook my rca's from the amp or cd player. It is all brand new. Sub, amp, and wires. It was working fine then it was unhooked for a few days so i can get my interiors set up right and now its humming. Any suggestions would be greatly appreciated.

Answer 1

Was it humming before?

If its brand new then i suggest you work them in.

Somtimes it might not be the amp nor the sub but could be something vibrating when you are actually using it.

Answer 2

I hope the extra ground wire fixed it.  If not, it still has to be a CD player problem.
