Kicker 750 watt amp with 2 kicker solo baric L7 15" at dual 4 ohms or dual 2 ohms?

[Hollen523]

i have the kicker 750 watt amp and i am wondering if i am going to put two 15" kicker solo-baric L7's in it, what ohms should i get? i can get either dual 4 ohms or dual 2 ohms. or should i down-grade and get the L5's. i just need an opinion by someone who knows what they are doing. ive blown way too many speakers and am tired of spending all my money. please help before i order this
