? bout walling 4 door suv

[07_ZX10 4]

right now my box is subs up, port back 20 cubes before subs and port with about 200+square inches of port tuned to 33hz, designed by chris at fishercustoms. It picks up lows and pretty loud, only metered before i built this box and was 149 on tl and did 151.7 on audiocontrol meter at local show. Now with this box, it sounds louder to ear, but havent metered yet. Problems now are i have bought 2 boxes of stinger roadkill bulk, did roof, doors and back door. It doesnt rattle bad, the back glass is terrible, but everytime i open back door, metal braces or pieces of the lock and handle are broken and fallin off. LOL. I got guy i work with to tig weld a rip in back door already. Anyway i got design from chris again to wall off behind front seats, I havent decided for sure if im going to do it though. Any opinions on if it would sound better or possibly louder walled? Its 98 expedtion, box now is like this:

this is old box when i had it metered:

new box is taller and not as long, gives me more room to mount amps.

wall design is this:

any suggestions or help appreciated, thanks

It you walled it and sealed the wall it would most likely be louder. No one can tell you for sure as every installation is different.
