Perfect cab, exactly what I needed.
This box fits perfectly in the extra cab of the Tundra right under the back seat totally integrated and hidden, the cubic feet is about .86 per sub, so I was able to find some shallow mount Kenwood 4 ohm 12s that require about .8 cubic feet. I put some polyfill in there ran them in parallel at 2 ohms to 600 watt amp sub channel and it just pounds!
