Sub box help

Looking for specs to build a sub box to fit behind my rear seat of a 2018 Tundra CrewMax.
It’s a 10” sub with mounting depth 4-7/16”. Needs .625 cubic feet air space for sealed and 1.0 for ported. any help would be greatly appreciated. Thank you

 

Reach out to james at tech 12 volts. He will build a very nice box get it to you. It will fit perfect AND he puts resin in it to make sure it’s sealed up tight. For the price of materials and time you will spend getting a box from james is a much better investment. Also, he will find out what speaker you are using and make sure it fits and the cut out is perfect.

 

So many easy options if you move the seat forward with Gately brackets. I have a single 12 in 1.7ft ported enclosure. Not even close to full width. Getting a foot back there is easy!

 

Can say from experience it's an extremely tight fit back there. With the hanging mat that covers the the rear window access panel removed, you've got about 7.5" bottom depth and top depth depends how tall you go. Have to also take into consideration how far your sub surround sticks out from the front and how much excursion it has. Sub has to basically nestle/play into the seat back of either of the side seats. Best thing to do would be message James at Tech12Volts like @Iamsecond mentioned, otherwise if you're dead set on building yourself I'd recommend getting some cardboard or foam poster board from dollar tree to create a mock up, and use a free sub box volume calculator to figure your top/bottom depth, width and height.
