Neo_frog Posted February 3, 2009 Author Report Share Posted February 3, 2009 My pioneer had similar problems. The subs would rumble, noise through the speakers. I got a new alpine 9886 and its gone, however, there is still a little noise through the speakers (engine noise), im going to get better grounds and new RCAs and see if it helps.I never tried grounding the RCAs like many people on this fourm have, did you try that yet? No haven't tried grounding the RCA's, but I'm gonna be buying a new head unit here soon. when i had this problem it was a grounding issue, check there. There are no chassis grounds. I have a big battery bank and each amp is on a different battery. Quote Need an install? Hit me up.[email protected]Got car audio questions?

What are the batteries grounded to? Is your Head Unit grounded to the battery bank or chassis?
