the biggest box you can fit is the biggest box you can fit through the opening of your trunk. ( mustang trunk openings normally aren't very big. ) make a shell of a box that u think is the biggest u can fit out of cheep plywood. and then go from there

get a pocket hole jig and build it in the trunk

I didn't look at specs on sub cuz im on my phone, but yeah that's off. Most 15s ported do around 3 cubes

So if i get a box that's l=20 W=18 H=18 and 1/2 inch thick mdf i should be around 3 cubes? (not counting the port) highly doubt that would fit though. I think the 15 might actually be an impossible fit -_-

(Area in trunk for mounting a subwoofer box: Height = 7" towards front, 12" at rear, Width (front to rear) = 26" maximum, Length (side to side) = 34" maximum between wheel wells (trunk opening is only 28")

That's what i was able to find for trunk space. The box's top width would have to be 28" and the height 7" (or have some weird type of box that is 12" and then slants down to 7") and a max 26" depth.

Unless I'm wrong boxes cant have sharp corners right?

Depending on power and goals most 15" subs will like ~4.5 cubes per sub.

The idea i might use is basically 2 boxes one 12" in height and the length would be up until the trunk height lowers to 7"inch and there a 2nd box would be attached to the first into the box. The inside of the box would be like the inside of the staircase. (best i could explain without graphpaper and a scanner)

I'm having a hard time fitting 3.5 cubes i think 4.5 is impossible with a trunk so small.

what are the measurements from where the height is 10 or 11? could try facing sub up port forward.

Yep, I wouldn't do a 15" sub in that car myself.

So maybe a 12? 2 12's would need more space then 1 15 right?

Well the box is great and it must be in bigger one so that it will really fit.

You'd be better off with tens or eights, so you can keep a rear firing enclosure. A single twelve might work. Just get something beefy, a nice box design, and throw gobs if power at it.

My vote is for a pair of nice 10s or a single mean azz 12"........My original setup was a single Havoc 12" in 3 cubes with 1600 watts and it was nasty loud and sounded amazing while doing so....Good luck OP

Second, I am running a single 12 Fi BL and it is more than I have ever wanted for everyday.
