Ive Had taht hifonics amp for some time now, first i had it wired at 2 ohms to a 15" l7 and now i have it moving 2 12" l5s at 1 ohm, and it is a beast poor l5's wanna die of so much wattage, i think it would be nice for 2 12" l7s, but its up to you, i had the 15" l7 in a 4.0 cu @ 40 and now have the 2 l5's at 2.2 each and both set-ups pounded really nice with that amp.
