got a couple NSv2 15" d1's, built the box and would like some input on amp selection (Sundown as im a new dealer). We running Street Beat 4 (unlimited alt, bat, amp... across the board). Box is 3ft^3 per sub and tuned to about 55hz, (subs and amp on same plane) bed cut into a single cab silverado. My question is i guess is what can i put to these things (within reason), money not being an option, 2500 per coil?? 4500 on each one??? if we use 45's should we dual alt? goal is 156db, which sould be easily obtainable, imo might get close to 160 with the luck we've had lately (outlaw rules, i can post legal #'s too)
