low rumbling "noise"

[Savag3 10+ year member]

I can hear a slight low rumbling noise in my subs( volume on 0), Ive checked all grounds (big3 1/0) tested with different amps so its not the amps, the grounds are all on passenger side frame rail. Just ran new stinger rca's (got a little quieter) out of options, i believe it to be at the deck or in front ( just installed new eclispe cd5100 ) [replacing old 5100 , also had same noise] When i change tracks i can hear the track changing (thumping) in the subs . . can this be from a dirty power source ? should i power my deck battery direct ? take ground to frame ? all inuput appreciated !

Try powering your deck from an external 12v source, like an extra battery..

If the problem goes away you can consider it to be a ground loop problem.. get back to us once you've tried this out..

Are your RCA's ran down opposite sides of the Power wire?

If not, perhaps you can try that since I've read and heard that it may be one cause.

yea power is run tru the middle rca's on both sides

Can this noise come from bad RCA's?
