Currently I'm running 3 10" MTX thunder 7500's in a sledgehammer enclosure, 2 Ohms, with a clarion DPX11500(supposedly 1500 wrms, but I've been told it doesnt put out nearly that), and I'm getting ready to upgrade to something bigger. I've been thinking about getting 2 MTX 9500 12" or 15" subs and I'd like some other opinions. I listen to mostly metal, hard rock, rock, and sometimes I'll throw in rap. Will not sacrifice SQ for SPL, I want both. What would you guys recommend?
