I've got 2x12 inch sony subs kicking around gathering dust, they;re not worth much to sell so i thought i'd try fitting them into my WB for something to do.

I want to fit them in the rear firewall so the drivers are in the tray, and build a box around them. Only (so far) problem is, the rear wall is corrugated.

Does anyone know the best way to go about making this wall flush so the subs bolt down smoothly? I can only think of using Marine ply with a butt load of silicone, but thats rough as guts.

Has anyone seen this done or have any ideas?
Would get pics of the wall but the camera had a coronary.
