Your best bet with those large, square subs is to go with a digital, class D mono amp. I'm talking Alpine's PDX series or better. JL amp...what ever, just make sure its an amp with a very high signal to noise ratio. the square subs aren't as clear as round subs, but they will blow the spl through the roof. so the better the signal to noise ratio of the amp, the better sound QUALITY you get from those squares. Good Luck!
