I used this sub for litterally 3 hours. Works great. I had it hooked up to a Kicker ZX2500.1 and it sounded amazing. The box is a 3 cubic foot sealed enclosure, with supports on each side, also has polyfil in it. They used 8 AWG wire for speaker wire. Box is wrapped in black carpet. Don't have pics but can get some stock ones.
^It depends on what you're looking for...if you want punchier,cleaner bass you go sealed.If you want it on the loud side go with ported.You're asking way too much money that sub and box.You also posted BRAND NEW but it's used,you can't use something and say it's new...lol.
