I used to build custom boxes and install high end stereo equipment. I recently bought a 7th Gen Maxima, and would like to see if there is interest in me producing a few+ of these sub boxes.
They have approximately 1.7 cu.ft. of air space as pictured. This is good for up to 2- 10" subs. This can be 10s, 8s, or a single one of the above.
The box slides in place, and keeps ~3'' between the seat backs and the subs. If you prefer, the front face can be used for subs, which can allow the use of 12'' subs, or 4 shallow 8" or 10" subs.
The construction also allows for the pass through to be kept. If you would prefer the pass through to be covered, larger subs can be used.

The beauty of this box is that you don't loose a lot of trunk space. This sits on the raised portion in the back of the trunk.

Below is just a mock-up of what would be constructed.

 

And in the car:

 

I'm still thinking about purchasing subs for my car (09) but I do like your style. I will let you know if I do, what would the cost be?

 

Are you still making these? How much? Email me if you are, so I can get your contact info. I'm in GA.

 

$150 for the box. Shipping not included.
Carpeted in your choice of black, dark grey, or tan.

I will have real pictures up soon, as I think I will be picking up a couple 10W3's in a couple days.

 

if only you did this for the fourth gen

 

Id be interested if I could get a 12w7 on one side the use the other side for an amp

 

This box is not deep enough for a 12w7. You could run a 12w6 though.

 

Bummer, well it'll just stay in the pro wedge box then. Kudos to you for mak8n this box though!

 

So, I built this box out of birch ply, and stained it to match the wood panels in the cabin.
I'll be running a pair of JL 10w3 off of a 500/1. With this amp I will be able to upgrade the subs later if I want to.

 

 

Im interested in a box you still making them

 

Are you still making these sub enclosures? Interested in one for my 09, how much?
