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

Hmmm good idea I'll try it on my next day off. Any idea what size box i need for the speaker though?

3-3.5 cubic ft at 32 htz

ported right?

 

[edudes13 10+ year member]

I used a box size calculator and its giveing me .6^3 with a 36.25 in long port. BS right?

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

 

[edudes13 10+ year member]

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.

 

[Mr.meyhem 10+ year member]

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.
