Ive tried 2 differnt grounds and the 2nd is better then the first, but it still taps my subs and still has a humming noise. right now its nto a big deal but in a couple days i want to power my 6x9s of an amp and i tried it already, when i turn it on full then the humming noise is outrages so i need to get ti fixed. so can someone give me all the possabliltys to fixing the humming noise. ppl r saying its my rcas but i tried regrounding them by attaching a wire to each and grounding it, and it stays the same so its not the rcas.
Does your hu have a good ground? you might try a ground loop isolater inline with the rca's. This is a last resort thing if you have ruled out the bad ground theory.
rca routing is a myth. yes grounding outside rca terminals can help in some situations. but not many. more likly bad HU to begin with or weak link in the grounding system or power system. Sorry to Dis'you Rave'n.
