i have noise coming thru the speakers and i believe that's due to the rcas now here is the other problem i can hear everything in the car thru the speakers like the engine rev or rolling the windows down stuff like that. Also if im listening to the stereo at low volume (very low volume) and i hit the switch to roll my windows up or down i can see my headlights dimming

Sounds like a bad ground, I would start with that.

Change/move your RCAs and grounds.

If you're having dimming issues, do the big 3. If that doesn't help, upgrade your battery.

you need to re do your ground on your amp.
