OK< my system consist of 1 15" MTX RFL sub, 2 JBL 1200.1 amps. I can ether shoose from a ported enclosure or bandpass enclosure. I think I am going to go bandpass, because it will have less ratteling on my car from what I am told. But I am open for suggestions. does anyone have 1 of thease subs and if so what kind of an enclosure. Anyone got dimentions. I can get the off the MTX site, but it can get confuing with the spanigh combined in it.
