[QUOTE="Lil Poot, post: 1581816, member: 561892"] those cars can get loud, i hit low 140s with 2 sealed SQ oriented 12's in an 87 ***** am. even with the backseat out though, your hard pressed to get 4 15's in one even if they're small box woofers (strokers aren't) the acoustics of the car make it so you get cancellation unless you have the woofers at the very rear of the car. its like a home audio subwoofer, put it in the corner and its loud, but in the middle of the room it sounds weak. a full wall would lower this effect, but is he serious? hes talking about adding a 2-300 pounds to his "sports car." he would probably sound better and get almost as loud with 2 ported 15's, and could possibly keep his backseat and see out the rear window. either way, i doubt hes going to touch 160's. unless it angled up with the window, the box would probably have to be fiberglass. im working on a ported box for my 12's now and the most i can get (box is mdf) keeping my backseat and keeping the box level with the tops of the seats is 4.3 ft^3. but yeah, tell your friend he couldnt handle 160 db daily, or even 155. he doesnt need 4 15's unless hes competing, and if he is, there are MUCH better cars for it.
