I just set my gains the way Jl audio said. I set them with a volt meter and they are accurate. any louder and the front speakers pop. right now im running a pioneer 860mp deck, eclipse 3422 amp bridged to 2 channels they say should be 140w per side. front seperates are ID csx64s. the sub is a IDQ12 and the sub amp is eclipse 33230 running mono at 400w. the sub is loud enough. but the total sound seems lower then i think it should be, just wanting a little more. I have 2 ARC 2050s coming and i was going to bridge them and run a amp to each seperate. will the arcs go louder then the eclipse amp? or is there something else i should do.
