Look closely, you can see it's tucked underneath.

 

I bought my box from them. It freakin pounds! I opted for the one without T top holders...they looked like they would be bounced around in it. Sure you could make your own for a few bucks, but good luck sealing it and praying it doesn't look like @ss. Ported boxes are for High end subs and generally dont hit hard. I paid the $200+ for my box, but I also paid $700 for the head unit. It's only money right?

 

I found a new one on local Craigslist for my 96 a few weeks ago and I like it alot. It holds both tops, I just toss a towel between the glass, sounds good running my dual 12" subs.
