Need some Box Help!!

[frkkevin 10+ year member]

Alright.. trying to squeeze in two RE SX 15"s into the trunk of my Jetta.. after a lot of design issues of trying to fit them in this is what I've come up with..

External Dimensions: 17(h)x39(w)x22.5(d)

The cut-offs in the back are 4" triangles, external.

I'm new with using BBP6 so if someone could use the dimensions I posted to run back through the numbers to see if its accurate I'd appreciate it.

Box Volume: 5.353

Tuning Freq: 44.92hz

is tuned kind of high, i take it youre going for an spl setup.

i suggest adding a triangle piece. to the back wall right in the middle of the port just to help on the air turbulence you want the air to flow as best as possible. and it will double as bracing for that back wall.
