Ok, the amp is powering my rear 6X9" speakers, so i guess those are my mids. The actual model # of the amp is Pyramid Gold Series PB-370G "Super Blue" (It's a class A). the 6X9's are Legacy LS6945RD "Red Series" speakers. (lol maybe i shouldnt mix blue with red ). Anyway, I've noticed that my power and RCA cables shouldnt be beside each other so I'm gonna run the RCA cables on the driver's side. I dont know if thats going to help, so for now I'll have my deck out of its mount and directly (temporarily) connect my deck to my amp right down the middle of the car. Anyone else have any suggestions?? I'm still puzzled about having 2 grnds and 2 12V+ screws on my amp.
