So i recently bought a new used car ( 2000 mitsubishi mirage ) came with a aftermarket headunit which is a vr3 ( off brand ) so i figured i would replace it once i got the money, anyways i hooked up 3 12" kicker cvr's and a hifonics brutus bxi1210D amp. everything worked perfectly fine until i was messing with it today and pull the headunit out and something happened ( no idea ) and none of my door speakers work, my subs work perfectly still. so i rewired everything and still nothing. the speakers buzz when my car is on ACC. no matter what ive done nothing works, ive changed the ground wire from the Headunit and still nothing. please can somebody help me out on this?
