Building a sub box, what is the boot size of a Yaris?

[Spades]

nice! unfortunately for me, I have the sedan and there was no nifty compartment to stash a sub. granted, i am only untruding into about 4" of depth into my trunk because of the custom build, but i am envious of hatch owners and the "stealth" installs.

BTW, what product are you using for the box adhesive? if its a glue product, it might not be a bad idea to line the box with fiberglass resin or silicone overtop of the corners on the seals...glues can shrink and get air pockets...I used liquid nails for the adhesive on my box, but i resin'd the inside of it to ensure a airtight enclosure.
