i was windering on how i could get my 2 12" alpine type r dvc to hit mid 140's in a 1998 chevy blazer. they arent hooked up yet and i plan on getting the box dimensions from one or more of you people because you know a hell of alot more than i do, lol. but anyways i read someone elses post who has pretty much the same setup as i do and everyone says it will blow? i have 2 12" type r's and 2 m501 amps with a cda 9835 deck. is it possible to hit mid 140's? if so im sure someone here can let me know how. thanks a million guys and ill try and help everyone else as much as i can with what i know about non stereo questions lol.
