I need to know where I can buy a nice speaker box for my
15" sub...anyone know a good site to buy it from

 

not to bash places that sell pre-fab boxes... but, make your own. all it takes is a sheet of 3/4" MDF (that home depot or lowe's will cut for you), a 1-pound box of 3/4 inch screws, a 7/64" drill bit, some silicone caulk, a drill, a jigsaw to cut the hole for the sub, and a 6-pack of beer to keep you occupied.

it's not a hard process, especially if you get some help from someone knowledgeable in the field. only downside if you get help is... the 6-pack becomes a 12-pack cuz you know 3 beers just won't cut it!

 

Ya, I agree with Lance Dogg, build your own. I would use liquid Nail in the joints as well though, and then run the caulk on the inside seams of the box.

 

Also, you can get some box carpet from any audio shop and 3M spray adhesitive and make it look pretty.
