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.
