Sounds great and is moving a lot more air, haven't played it too low yet. Once I actually tune it instead of just turning up the gains, I will post some results once subs break in a little. I hung a shirt in the window after this video, and it was doing a pretty nice shirt trick. I'm running the amp at .5 and the subs love it. Thank you to David @ PSi for getting my subs built and shipped out before Slamfest. Oh and btw I'm running the new Pioneer DEH-PRS80, its very nice, love the bluetooth also.
