Are you alluding to the fact that you broke the windshield in your car with your system with your first statement? If so I call major :bs: , you may have made a cracked windshield worse, but you didnt blow out a windshield with your setup.
Steve meade from Steve Meade Designs is running (last i knew) 4 18" BTL's in his SUV, and hasn't and will not blow out the windshield. It simply can not be done on a daily driven vehicle. Even the competition level setups barely see a chance at such an accomplishment, in fact, I've never seen any thing about a windshield blowing out durring such an event, cracking yes, but blowing out, NO.
What about the SPL guys running Honda CRX's for competition who can't seem to blow out their windows???
And your second comment is really nieve as well. But kinda follows the first comment as show how much knowledge you may or may not have.
How many competition setups running 20,000watts do you see using anything but a vented style enclosure? I've never seen a sealed box in competition ever. If yours or someones you know vented box sucked then I would look at the builder, not the box.
Not to sound like a dick, but car audio discussions are just like automotive discussions, they should be left up to the ones that know what they are talking about, and one should only offer opinions on what they truly know. Not make a general comment about something sucking if they really have no information to back that up.
