I would check your grounds,make sure your grounding to bare metal.Did you try differnt rca's ? Then turn the levels down on the loc.

You could be experiencing feedback. What happens is the sub produces pressure in the trunk which moves the rear speakers which produces a signal that is sent to the sub. I've also seen this happen when closing a door. Try getting the signal from the front speakers and see if the problem goes away.

i already tried changing the rca wire and my ground source i noticed that the rublimg changes with my rpms since it only rumbles when the engine is running once i get past 2000 rpm the rumbling stops and if i disconect the rca wires from the output cinverter it stops so it must be sumthing with the cars factory audio system im guessing

sounds like you have a power wire laying on top of your speaker wires going to the converter,or a striped speaker wire conducting with the body,or loc is just junk
