My buddy has a Fosgate 12" in his Shinoda Mustang and i took my Diamond out and put it in it's place. Just gotta say... wow. I have never been a big fan of the new Fosgate but I gotta say this 12 impressed me. Was in a sealed box (1.5 Cubic feet) Single 4ohm coil. It was light and fit right in the corner of the trunk. Hit the lows VERY nice and was very clean sounding too. Tried everything I could to get it off of him but no go Oh well anyways thought I would post my experience... I might just pick me up a punch 12
