I'm guessing this is what he did by the pic cause it looks different to me. I haven't went outside to look at mine... But look at the side view pic with the seat down and you can see how it appears to have spacers between the floor and the black bracket underneith the seat.

 

Dang. Joe is slippin I emailed him about his dual 12" and still no reply an its been a month.. I wanna try the dual 12's enclosed to see if they beat harder than my ported dual 10's...

 

yeah I emailed him again but no answer yet. I think I will go with the bigger box for 140 and check that out should be nice I hope. Just finished dynamating the front doors and making new spacers and adapters to go from 6x9's to 6.5" components. I also took out back seats to dynamat back wall and make amp rack. I was hoping to get everything done before my cruise to the Bahamas on Saturday but with work, the tornados, and rain not much time to be outside. I will post some pics of the work when I return and start to piece it together.

 

Throw some spacers in there. Ive seen people use washers or a piece of steel from a hardware store. Shouldn't be to tough to do.

 

I have an 08 Crew with one 12, it turned out very clean and nice, will post pics if you would like, I fiber glassed the base and wood top and wrapped in carpet.

 

If you use too big of a spacer it wont fold up right though. The ones I got with my foxbox are 1/4-1/2" thick I believe. I didnt think 1" spacers would allow the seats to move up correctly.

 

I went out and got longer bolts, then added 2 large nuts (large enough for the bolts to go through) as spacers. They were about 1/2" thick each. It was going to be temporary, I was planning on getting a piece of square tubing and using that, but these worked out just fine, so I left them.

 

JL Audio steathbox. I love mine.
