Hi i'm ready to upgrade from 2 12" kicker cvrs i wanted to go with 4 10s if i could. i was originally thinking 4 pioneer 350 wrms subs i can get for 70 each locally. But a friend of a friend has some hookups through Fusion Audio. He has 2 12" on two 1100rms amps and it wangs hard. i was thinking of getting a few of there middle end subs ( 300 rms ). Has anyone had experience with Fusion Audio subwoofers? they look pretty decent
