The aluminum didn't rip through the surround, the aluminum cone itself actually cracked and jjust looked like it ripped through in the pic until you looked closer. This thing blows the destroyer (in original and hybrid state) out of the ****ing water. I'll post up pics of the box and everything later, but the lows just kill you. Still tinkerin around with all the settings but I got it goin good and loud right now at 1 ohm. Might drop it down to a half ohm in a couple days we'll see. I'll get pics up later tonite I'm off to the Boars Nest show!
