[QUOTE="toy4x, post: 2955612, member: 571120"] ran a ground from head unit to battery...no change.. just noticed if I move the Rca inputs at the front amp,wiggle them while they are connected, I get popping and big differences in noise. Sometimes it goes quite if I hold it a certain way and very loud if I leave it alone. Also, when trying to set gains using DMM...not even to max potential of amp, I hear a strange buzzing noise coming out of amp every time I increase/decrease gain. And stays humming when after it is set....this is problably the cause of all my problems. Now do I have a bad amp input? Where would I go to get this fixed? [/QUOTE]
