I was thinking about upgrading to the JL Stealth box but I'm not willing to relocate my jack or mount my amp on the back wall. So with that said, what sub will fit in this box. Here is what I'm trying to do. Right now I have an Infinity sub that puts out 350W RMS. I would like to Push 500W RMS with this sub, but I dont think it will fit. Any suggestions?

 

subs too deep

 

Technically it would make it in the box. But like Styx said it is too deep because you would block the vent on the back and cooling would be at a 85% loss.
