I have 1 MB Quart PWE 304 which has a 6-1/4" mounting depth. I am thinking of going with a modified box like this (The modification would be routing out an area for the magnet so the thing will fit and having only one cutout/combining the two chambers for a larger total airspace). Anyone running a sub this deep without lifting their seat or using a box that sticks out in some way? Post pictures if you do Thanks!

Looks like I could router out 1/2" from the 5/8" for the magnet and then use some ABS or something to make a spacer ring where the basket mounts to get 1/16”-1/8" clearance for the magnet from the box. Unless the box is already routed. Does anyone know?
