i use a Memphis 1000 watt mono block ( could use 2000) to push 2 12" Kicker CVR dual voice 4ohm bridged in a Super BASS Probox *that was installed through the back seat and some cutting and bending was needed on the back dash, then i beat it back flat with a dead-blow hammer* god it was a pain in the ass gettin that huge box in there, but at least itll be a pain in the ass for the ass hat that tries to steal em next time too,
i use a DB Drive spa 85.4 680 watt four channel to push 4 6x8 Kickers ( not sure which model anymore) i know they were the most expensive ones i could get last year ( SOUNDS EXCELENT!!!!!)
i used to use a Hiphonics ZXi1000 four channel in my jeep pushing 4 rockford 5" mids, and that thing was AWESOME, but someone busted my window and stole it,
Im alot like you in that i dont buy ANYTHING just because its the cheapest, i normally spend the money on the best.
The system i have right now can play hard banging rap ( with no trunk rattling), deep low bass tones, very nice mid range and wonderul highs for rock music and even loud heavy metal sounds great, the last time i was tested it measured 186 dbs
