Hey guys, I'm getting the Kicker Solo-Baric L7 12 subwoofer. rated at 1500watts peak, and 750WRms. It's one of those square 12" speakers in a sub box. They only thing is the guys who fitting it told me that fitting a vent in this box will blow the sub. I'm just a lil suspecious as I've seen many sub boxes with vented boxes. Could someone please tell me what's the difference between having a vented and non-vented box?
