I'll do it for $100, I'll also use my brain and not some calculator....:p:

Seriously. If you want to learn how to build/plan/layout a box from scratch, I'll teach you so you won't have to start another thread like this.....just gimme a PM

3.531cu ft internal
38Hz tuning
¾: MDF
32” wide x 14” tall x 17.5” deep
Port = 12.5” tall x 3.5” wide
Length will be an L on either side : 12.5” deep and then 3.75” behind each sub

it will make them sing I promise.

you can adjust ports as necessary but I have tried lower and higher on dozens of R's and 38 gives them awesome bottom end and very clean all around bass. it is mean and very loud.

anytime bro. I hope it works for you well. that box design has served me very well for 100's of installs.

4.25 tuned to 34-38hz is what i found to work nicely with 2 R's. sub up, port back in a blazer.

ive done them bigger and smaller both and that design retained alot of the snappy punchy bass from kick drums ect while still hitting as low as 24hz, whereas a bigger box loses its punch some.
