problem with new system???

I just installed a new system with all new speakers, HU, and 4 channel amp to the speakers... when the car is started and the gas pedal is pushed there is a wine that matches the acceleration of the car. So the more I push the gas pedal the higher pitched the wine is... If it matters it is coming from behind the front passenger seat, by the rear passenger seat and that is also where I ran most of the wiring. Any idea what that is?? any help would be much appreciated

thanks!

My first guess would be a bad ground.

How close are your RCA's to your power for the amp? That can also be an issue as far as whining noises coming from your audio system.

its about a 2.5 or 3 ft section of 4 gauge wire grounded to a bolt that held the stock monsoon system in... I sanded it down a little to try and get bare metal as best as I could, is 3ft too long of a ground? where is a good place to ground to ?

your picking up the alternator wine. idealy you want to run the amp power wire and the rca's on opposite sides of the car. other was to go is to get some really good rca's that have all the insolator crap in them, like monster cables. before you go and rewire everythign try getting a noise filter, ground loop isolator, rca filter, or a power lead filter. any of these are to reduce the wine your gettting
