Here is what I'm going for without actual specs.

http://img513.imageshack.us/img513/6629/60833969.png

I did some measurements of my trunk.

Constrained Box Dimensions (Outer):
Depth: 31"
Height 15"

Material: .75" MDF

Tuning: 26 Hz
Volume: 2.5 ft^3 After Displacement

Width: ??
Port Size: ??
Port Length: ??

If someone could draw me up a design to those specs, I would greatly appreciate it.

31 deep 15 tall 15 wide port 2X13.5 28.25 long gives you 2.5 @26.2hz

I didn't post all the necessary information?

By length are you asking for depth or width?

I don't know what the width should be. It's the dimension that isn't constrained. It can be whatever works with the other dimensions to get the specs I'm looking for.

cool so do you want it double baffled???


also can i decrease the length some so i can compensate for a larger width for the baffle?

Double baffle would be nice but I don't think it's necessary. Do it if you think it will work best. You can change the depth by some, but I'd like to be as close to 30-31" as possible. I don't want a box that goes across the width of the trunk.

Let me know what you're thinking.
