I have been contemplating on buying 2 15"Kicker L7's. I know i want 2 15" subs and if i could get some input on this and what you think would be something good to invest in let me know, it would be a great help. Also if anyone know where i can buy concepts amps(Concept CC-D2400A) that would also be great help.(for under 600 bucks) Thanks Everyone
