I've been talking about it for a while, but I finally put some numbers together. My trunk is very small because it shares space with the fuel tank. Dumb, I know. I can't port through the ski hole, I have to port through the OEM 'woofer' 6.5" in the rear deck. Drivers of choice are a pair DD 2510's.

Numbers are as follows:
Width: 36"
Depth" 13"
Heighth: 20"

These are pretty much maximum. Doesn't yield a whole lot of space, I know. The 2510's have a depth of 6.5"... I prefer a dual chamber enclosure, so I can have a window so I can see the front of the subs.

I'll put something together, but I'll probably leave out the way the vents need to be angled to make it through the rear deck. Also, I'm not really sure where to locate the vents in relationship to the rear deck. Hopefully, I can design something with a degree of flexibility for ya.

Definitely. I'm still looking into amplifiers.

Thinking maybe the Alpine PDX series. Good looking small amplifiers.

If need be, the depth can be more, too. If I mount amplifiers on the trunk lid, which I don't really want to do, I'll have a bit of room. I'm planning on putting the 4 batteries in the spare tire well for hydraulics. Each pump will be on opposing sides of the trunk. Like this Lexus:

Vent location is going to be a pain in the ass. I'd like a pair of 6", but I may have to run a pair of 4's...

For reference, here's what my trunk looks like, minus the install:

Still working on this. I don't have any parameters for the 2510's Neutral

I'm in the middle of it right now. You def have enough space that will allow for tweaking later on, and the use of 6" vents. Hit me up tonight if you want to talk in more detail. I've got all my school stuff done for the weekend and nothing else to do really.

If you do, hit me up about an hour in advance!

Here's what I came up with, with your given dimensions. I left a lot of room to for tweaking, and hopefully this can give you a good idea of what direction to go in. I used an ARC audio XXD - 10 for the response/imp curve because I felt it should be rather similar spec (FS, QTS, VAS) wise to the 2510, given what the 2512's specs are. I also have a plot for 3 other woofers in the "same box", for better reference.

Sweet! Should be fun! It may be a little while. I still need to get an amp and get these built.
