What causes that annoying sound coincident w/ your RPMs in your speakers? Is it a bad ground or what?
TIA,

Re: interference with rpm (89GLi)

Alternator whine is normally caused by a bad amp ground.Other causes can be amp gain set too high,bad RCA cables,RCA cables are routed too close to hi current/hi power cables,or RCA connectors on the hu or amp are bad.
