I'm helping a friend re-do a system in a 1990 Camaro. He has some 15" The Crunch subs, that came with the car, they work, but the system is shotty and needs all rewired, and a proper sub box to put. (The subs just hang from a top plate over the well in the trunk. My question for you is, if you still have those Crunch subs I saw in a post on here, could you tell me what watts they are, (the impedence sticker on the magnet says 8 ohm), also what cubic foot would I need per sub when we build a box? I am hoping you know this or maybe you have more info from the subs you have. Any help you can give or maybe a website I could use to find the info would be great!
