I think fox box is out of business. I would do it the old fashion way. Get some graph paper, take measurements, go to home depot and get a sheet of 3/4" MDF ($40 a sheet), liquid nails, some screws, and go for it. Cheaper and it makes you feel sooo much better when you can say "Yep, I made that asn it sounds awsome" plus you know it is quality made. Just be sure you have an alarm first, I learned that the hard way.

^^^ I had a Probox and sold it for a Foxbox and it is WAY better. Only issue with the FB really isnt an issue with the box itself but rather the maker; Joe.

 

You might think Foxbox is out of business, but thats because Joe Fox doesnt like to communicate at all. Get pissed enough and he'll bite back with a nasty comment or two, but good luck getting anything besides aggitated, annoyed, inconvenienced comments from him. The company is still somehow still puttin out quite a few boxes though

 

^^^^^^^ sad but true. He is really lucky his product outweighs his personality defect.

 

if you dont mind loosing your middle seat you could do something like this here
it pounds hard for 1 kenwood

i also have the cheapo ebay box under the back seat with 2 12's and its inaudible with the kenwood hitting.

 

resize your picture. the reason you cant hear the 2 in the back is because of the cheap ebay box. THAT is the difference between a quality box and regular box.

 

sorry bout the pic size, i just resized them and they still show up big. my bad

yes i know about the box, i was thinking cutting it in half and sealing it so that its 2 seperate chambers.

 

its only 1 chamber for 2 subs? Yeah thats enough to kill it right there. Defniitely make it sealed chambers for each sub, and make sure the walls are at least 5/8" thick MDF sealed with glue, screws, and caulk.
