oh I doubt it. if you use glue it's pretty hard to destroy a box, especially with only one 15 on 1000 watts.

3.5 cubic feet would probably work, though it's definitely on the small side. Do you have enough room to give it about 40 sq. inches of port? depending on what you tune to, the port could be fairly long and take up a lot more space. In your case I'd tune a little higher, maybe 35-38 hz to help cut down on port size.

never herd of 11/4 mdf. but almost every box without any bracing that we've put an MT into has broken at some point but i have a feeling if ur a carpenter you know whats up. Have fun with the sub and double bracing really helps

yeah, it's called just inverting the sub. Many people do it and it doesn't affect the sound.
