I haven't really done any mods to my car yet. The only ting I have done is put a K&N air filter in it. I've doing more with my stereo system instead. I have an Alpine head unit, an Alpine alarm, Boston Acoustics components in the front door, Boston Acoustics Rally in the back door, an MTX Thunder 6000 "12 sub, and 2 MTX amps to power the door speakers and the sub along with a 1 farad cap, with stinger wiring.
