radio noise

[matthigh31]

I bought a new double din DVD player for my dash.. hooked everything up.. turns on speakers work.. thought all was great.  So i get in and am driving and i can hear this wineing noise coming from the speakers.. gets louder and softer with the throttle.. i tried a noise filter.. didnt do any good
