Well, whenever I can get the time and funds to do some serious work to the ol' Ranchero, I'm gonna start on this idea

I noticed there's an insanely huge amount of storage space behind the bench seat, and two neat little storage compartments that run up under the bed. I'm gonna start trying to draw up plans for an enormous subwoofer box that would pretty much fill the entire back. If it works and if I can get the airspace right, I'm gonna go with either two round 12s and two solobaric 8s or 1 round 15 and two solobaric 8s. And if possible I'm gonna try to port that monster lol I'll have the deepness AND the punch. I have a cousin that is getting started in the audio biz, so I'm gonna present him w/ the idea since the truck was our grandfather's. I'm open to suggestions
