It says the substructure woofer cutout out for the RS 18" is out of stock. Any chance the SI cutout is smaller and I could just make it a little bigger? If not, any idea when the version for the RS 18 will be back in stock? Thanks!
In case anybody else is wondering, the RS 18" fits in the SI version of the box. I got the SI cut out for the interior and exterior portions of the box. According to Eric the inner cutout is the same and the outer one is a little bigger on the SI box, but it isn't bad. Especially if you paint with something thick like Duratex.
