Im looking to purchase a 15" Si Mag. Ive got no cash but ive got a Fully Loaded 15" BTL that ide be willing to part with for one, just put a fresh recone on it last week so its good to roll, looking to get out of the SPL game before i get permanent tinnitus or however you spell it and go with a more SQ approach, probobly gonna throw it in a small sealed box and run like 1000 - 1500 watts to it
