had the same problem, ground loop isolater at best buy/walmart, $13 fixed it, it is just the radiated electrical pulses from either the surplus of voltage needed for the sparking in the spark plugs or the smaller and closer ones emmited from the other components throughout your vehicle such as lights ac/heat fan etc. Electricity does follow the path of least resistance, however when the current or voltage is increased at points you get stupid electricity that trys to go everywhere, and the retarded ones fly out of the wiring and pass through the air much like sound waves, and these are entering either the rca/speaker wires and causing the speakers to make a noise. If you rev your engine do you hear a humming noise increase in volume with your HU turned down low? The ground loop isolater is basically a noise filter, i can't tell any difference in the quality of sound since i started using it, but you might want to try making sure your wiring of power/remote wire is away from the rca cables and speaker wires, check your ground as well, possibly relocate, couldn't hurt.

alright i figured out what it is

it is my rear rca's. the sound only comes out through them so this is what i did and help me figure this out

i disconnected the rear rca's at the amp and the noise went away, then i hooked the rear rca's to the front rca's on the amp and then the noise was in the front. so then i left the rear rca's unplugged at the amp and put the front one's back in , now i am getting normal music sound through front and rear speakers with just the front rca's in the 4 channel, but if i disconnect the rear rca's behind the deck the sound is gone from the rear speakers. so then i went back to the amp and played with the amp1 gains and amp2 gains, amp1 still controls my front AND amp 2 controls my rear but there are no rear rca's plugged int the amp

sorry if this is confusing but shit i can't figure this out

P.S i always have music through all 4 speakers just rear one's have the static
