Input:
I actually bought 4 of these thinking i'd shoehorn all 4 into a small custom rectangular box to go behind the back seat of my Chevy crew cab. After a bit more research i opted to only put in two instead of all four. They Thump amazingly well considering the 11in tall x 48in long x 6in deep inclosure. These two are being driven by a 400 watt Jensen 2 channel amp. Kinda flat at Very low hz but for better lower response U need a 12in anyway. Too high up the range & they tend to get muddy.  But for me this is exactly what i needed to get that extra bass kick ater replacing all 4 factory speakers & loosing the factory low volume bass.  Well worth the money!
