well i finally got rid of those l7s. i paid 450 for the amp (audiobahn a1200DQ which actually is a good amp) and 2 12"l7s in a ported box, and sold the subs and box for 450 so i got a free amp . anyhow i want a single sub 15" or 18" for this amp. i have about 800 to spend but dont necessarily want to spend that if i can avoid it. avalanche 15 or 18 are tops on my list for now but might have to wait a month or 2 for them go get in if i order on monday. help me out here
