Props to a nice small enclosure and utilizing the dead space up there.

Are the dimensions above what you used in the car? Was planning on doing the same thing. It's a great idea!

H x W x D
7 1/4 x 13 x 5 1/4

 

My final outside dimensions were 8.75x12.5x7. Using 3/4" MDF that put the inside at 7.25x11x5.5 for a volume of 0.254 Ft^3. Subtract the driver displacement of 0.024 Ft^3 and you get the recommended 0.230 Ft^3 from Fosgate.

 

do you happen to have the dimensions for the cut out you did with the amp?

 

No I don't. I just took a scrap and cut the corners off. I would say to start with the footprint of you amp.

 

Sorry for the late post, but I'm wondering if you can put the back seats into their recline position with this setup? If so, this is absolutely perfect.

 

Yep, it reclines no problem.

 

Thanks for the response. I have another quick question. I'm looking into putting an enclosure here, but the sub I'm using needs .3 cu ft. Is there any way of making the box a little wider, or is depth the only variable with the box in this location? Thanks again.

 

You can go an inch wider before running into the rear seat latch / tie-down. But to get the .3 cu-ft you will need to also go an inch deeper and this may interfere with the spare tire access cover. I can send you my Excel spreadsheet and you can play with the numbers for yourself. Let me know.

 

Here, try this... http://dl.dropbox.com/u/28602710/Sub%20Box%20Size.xls

 

Wow, that is extremely helpful! Thanks again. I can't decide whether I'd have easy access to the spare compartment, or have the "proper" sub box dimensions.

This will be a great help, though.

 

The spare tire access cover will ply side to side so for the few times that you need access I'm sure you can manipulate the cover past the enclosure.

Just a side note... the sound is incredibly punchy and clean. My rearview mirror vibrates "BIG-TIME" to every bass note but its not like thunder that you hear from larger subs. What I'm trying to say is that it is a very satisfying in-the-car sound experience but it won't impress the teen crowd as you drive by.

 

Thanks again for all the help. I bought an amp and sub today, and will be installing this weekend. I was wondering how you secured your amp down inside of the spare? Thanks.

 

You can see the top view of the board I made on the first page of this thread. I used a scrap piece of plywood and drilled out a groove for the tee handle of the spare tire anchor bolt. I then cut and glued 2 foam blocks that I got from some scrap packing material to stabilize the board. These blocks were about 1.5 x 1.5 x 6 inches. Gravity and friction fit hold it in place. Once you cut the corners of the board off just place it is the spare and give it a whack to make an impression of the anchor bolt. Then remove the bolt and trace out the profile around the impression.

Good luck.

 

Great job with the box and mounting the amp! Where did you end up running the ground for the amp to and how is it working out?

 

The ground went up the same side as the power (non-drivers side) but not far. I lifted a bolt at the rear seat bracket and secured it there. RCA cable went up the drivers side. This separation of power and signal worked out with where I found an existing grommet going through the firewall on the non-drivers side. I've had no problems with anything coming loose and the sound still thumps more that I need. I usually set the sub to -8 on my head unit and that still wobbles my rear view mirror. It sounds great with the Alpine component speakers in the front and Polks in the rear.
