the 12's were 700rms each and the 15 is 800rms, Box is ported and i dont see it on the memphis site but the port is wider then the ones they have listed
memphis C315D2
Mclass 16-MC1.500
It pounds but ive never had a 15 before it just doesnt seem to pound like my 2 cheap power acoustik fubr 12's did. Any thoughts?
