I can't afford full retail but I definitely want to upgrade. I currently have an HDS 315 on a soundstream 1600 watt amp. Thanks

Okay so i got a 6.4 cubic ported box for 2 12's(not sure on port size or tune) with a hifonics ZRX 1800.1D amp with all stock electrical and i was thinking of two soundqubed hds200 12. Do yall think there is any better subs for $100 a piece?
