Instead of putting so much into making it "look" good...why not spend more time making it "sound" good. That would be the hard part. Main thing would be to fine tune an enclosure for the subs, upgrade the electrical system, custom kickpanels with enclosures for the mids, and one helluva sound processing unit. Do like 4 Pyle 12's, each with a Pyle 2000w amp on it. Maybe 2 sets of Pyle components up front, each with a Pyle 1000w amp on them. Fill the doors and floor with concrete. Might actually bang out a 130.
