Old School Cerwin Vega Stroker enclosure help

[High Dro]

I've recently come across two old school cerwin vega stroker 15's dual 4's and had a quick question before I purchase them a little info on my car it is a 2005 Honda accord sedan my cars trunk has close to 11 cubic ft of usable space 36" wide 17" height 31" Depth the 2 15's needing 8.46 cubic ft not including port and woofer displacement has me wondering if I could get away with using 3/4" 13 ply birch instead of 1' mdf so I can shave some weight and so I can gain some wiggle room for the baffle design they will be powered by a kicker kx 2400 for the time being only because I got it so cheap due to me working at best buy they would be firing into the cabin sealed trunk install
