I was thinking about ripping out the entire interior of my 01 ram 1500, and doing the ceiling, door panels, dash, and pretty much any open spaces with fiberglass enclosures that could hold an array of neons, amps, subs, and speakers. But i heard somewhere that fiberglass was mainly for show vehicles...cus fiberglass couldnt handle the dialy stress of driving. is that true? Cus i dont want to spend days making my truck perfect, and then have it gradually crack and fall apart. Any help would be greatly appreciated.
