right now I've got two 12" Eclipse Titaniums with an 1800 watt sony xplode amp (yeah the octogon one...I know laugh). A Kenwood Excelon head unit running 3.5" JL's in my dash. A big MTX 4 channel running two sets of Clairon Pro Audio 5 1/4 components. One set in Q Forms kick panels and the other are in my rear side panels. 4 gauge stinger wireing, 120 amp circut braker and 2 2 fared caps. With a Viper alarm. It actually sounds good enough that I've got two extra sets of taillights because they (my subs) keep breaking mounting tabs. And my rear wall where the latch bolts to is tearing so my latch doesn't quite tighten up anymore, in other words my trunk has about 3/4 of an inch of play right now. Oh yeah and no more rear seat back, it just kinda lays down most of the time. I just picked up an 18" Kicker Solo X. After I figure out where to get 10,000 watts I'll let you know what it does to my car
