mtx's 9515's are that great either. they definitely can't handle the power they're advertised to.
my buddy has one temp(free) installed to fill his box space. he's an installer at a big shop here and he's gotta have something to show. it's a 9515 with a memphis m-class 4000d running 2000w rms and we can smell the coil strong.
look into more unknown brands man to get what you're looking for. mtx ain't gonna cut it. like b.campbell said, the only 9515 i'd touch would be a digital designs.
