my last setup, which has to be pulled now that the car is totaled is
clarion pro video/audio fold out head, 9300 7band eq, 3band parametric, dsp,active crossovers network. running into two orion red 2 hccas. highs and mids come from 6.1 perfect components(custom fiberglassed and filled door panels) in the front and two perfect 10's in a custom built in the trunk box.(yeah, a real pain) box was ported and tuned to 46 and port fire through back panel to increase db in cab and reduce trunk vibration. alt gauge power supply front to back and 12 gauge pro comp wire amp to doors. 10 gauge wire amp to subs. 2 1 farad caps keep the volts continous. all wire is phoenix gold comp including the rca's. sound is a funny beast, a low impedience ground can through the whole thing for a loop... i still design systems and boxes(newer sn95 and ups are a pain to put subs in, but if anyone needs specs and such let me know..
