Its a 139.9 bassrace set up built by Robin and Chris @ bassheadsent.net. Currently: 2 Psi Platform 2 12s (D2) + Flatline Audio FL1 @ .5 ohm. Pioneer 80PRS deck. (8) Krome Audio 6s and 4 super tweeters in the doors. Does a 148+ on music legal door open. And outlaw does a 149+ but haven't retried it in a while. I'm not sure how much longer I will have the truck, but its the cleanest Xtreme that I've ever seen. I'm looking to trade it for something, or trade + cash for it.
