I have a fosgate power 1500.1 amp. it puts out 750w x 2 at 1 ohm on each channel. I want to put either 4 12's or 4 15's on it. I was thinking (eclipse SW7124DVC.T4) or eclipse SW8152.4 15". would this be a good set up? if i went with the 15's would they be under powered? Or how about 4 infinity kappa perfect 12's? Any suggestions please?
