I bought a custom made box from a member on here well over a year ago to replace the factory bose one. I believe I got one of the last ones he made before he stopped doing it. Too bad though because quality, customer service, instructions, and price were all great. I put a JL w8 powered by an Alpine amp (with a rux knob) in it. Sounds amazing paired with the factory Bose speakers. I'm very impressed with how hard it can hit when you crank it up. Sounds very clean and crisp at normal levels. Very glad I did it...
