I've got alternator whine on my fronts only. I've checked all grounds, even wired the power for the HU directly to the battery (+and - ) and I still get whine. This deck will drive speakers without noise, the noise is only present on the front and rear preouts. My amp/RCA's are fine (Kicker KX600.4) I can hook up an MP3player to the RCAs (at the HU) and there's no noise.

Anyone else do an install with one of these decks? Its got a USB port on the front.

jvc=noise
alt may be spun
plug wires may be leaky
try a noise filter

 

always make sure ur rca's are opposite ur power wire for speaker amps. And make sure your rca's are in the the right direction b/c some rca's are directional. If you are only getting alternator wine out of the fronts maybe there is some interference between your front speakers and the amp connection.
