I have a 94 honda whith custom fiberglass enclosure/amp racks. the system was there when i bought the car. its powered by an xplod head, 1 orion 2100 hcca pushin one 12" JL audio w7, and a pair of orion 225 hcca's one powering a set of MBQuart components up front and another powering a set of MBQuart 6x9's in the rear. I am having a couple of problems and am looking for some help. #1 when the sub hits on some tones it sounds almost like its bottoming out or maybe the box might be too big? #2 I need some wiring diagrams, or some help about where to get them? #3 I recently blew one of the 50 amp fuses inside the 2100 and wondering if this is common and/or how to fix it? thanx for any help from everyone even if you only read this. keep it loud = hurt someone's feelings
