Not an f-body...but...
2 12" Pioneer DVC subs, 400w nom/800w max, running in 2 ohms off a Soundstream XTA880 880w amp. Power rating is 440x2 at 2 ohms, but it most likely doesnt put that amount out, but oh well. Oh, and thats a 2 farad capacitor as well. I have a Pioneer DEH2500 head unit, nothing special, stock front mids and tweeters, and the rear deck speakers are just some sony xplod 6x9's. I think it sounds pretty sweet, maybe a little too much bass at times, but oh well
