[QUOTE="LordX, post: 8179832, member: 613621"] Ok, I did the following tests: 1. Turned off head unit - then turned off the car and turned it back on again - checked to see if AMPS were powering up even when the head unit was off. Result: Amps ARE off then the head unit is off. 2. Removed RCA inputs from Amp - and (leaving the Head Unit OFF) I Started the car. The Noise/whine is still there in both cases. Recap - Whether the head unit and amps are on or off makes no difference in the noise - and the RCAs being plugged in or unplugged makes no difference in the noise. Any thoughts? [/QUOTE]
