I just got an amp and sub installed yesterday and when i start the engine, theres a low pitched noise coming from the front speakers that gets higher pitched when i step on the gas pedal. The noise completely goes away when the speakers are turned off. Its kind of annoying when the volumes down low. Any help on how to fix this?

that's alternator noise.
it's caused by one of two thihgs.
usually a bad ground at the head unit or amplifier, or the gains on the amplifier are turned up too high.
