Hi all, I just wanted to show some pics of my recent fiberglass backed box that was inspired by this post. My system as it sits now has: alpine cd/mp3 deck, front speakers: Alpine type S 6.5" (perfect fit) rear speakers: Alpine type S 5 1/4" speakers mounted into the rear door panels (removed the factory 6x9's as the sub box now covers the place where one of them was) Amp: Alpine MRP-M450 Mono Sub amp mounted under passenger seat, and sub: Alpine Type S 10" mounted in custom built box, covered with Herculiner as my vinyl job looked like crap and was not very durable.
