I've been searchin up and down these threads for a solid enclosure for (4) 12" Subs and am not finding much. I'm upgrading from two Mofo's to four Kicker CVX 12's. It's gonna be sitting in my Explorer, so I've got plenty of room. I'm leaning on CVX style, subs up ports back. Does anyone have any tried and true boxes they have built before that they could pass on to me? Or any Quad 12" enclosure diagram/build plans? Thanks a lot guys!
