ok...i have an L7 12 in a 1.25 sealed box on a JBL 600.1 amp....sound pretty good, i had no idea what "good" was tough!!!
i got my brahma 10 in a put it in the same box, just put a new baffle on it, ......WOW, amazed me...just as much SPL or more than the L7 and way way way way better SQ!!!
getting a new alt soon ...bout a 140-160A, hope it sounds even better...
