I have 2 15in kicker cvx subs in a 6 ft3 box and I really want the kicker zx1500.1 but money is the issue here. So i'm thinking of getting the zx 1000.1. Right now i have an mtx 1000xd amp pushing 1000 watts rms but i think the birth sheet says like 1017 watts and the kicker 1000.1 says like 1200 rms. So i don't want to buy another amp and it not push any harder than the one i already have. Any advice?? Also if anyone knows of any other kick ass amps that would be good for these subs let me know!!
