Tiying in at head unit to the factory wiring, amp is on swing down between rear seats...rca's down one side, power remote turn on down other side, big 3 done 2 gauge running to back..New cables, new wire......Huge frustration....This aint my first rodeo, but I feel like im doing something stupid here...Both amps, one a crunch, one an older hifonics are 2/3/4 channel amps...One set of preouts on HU going to EQ7 3 preouts off that...Could be I have something on head unit set wrong for full range out......ARGG.....
