2 12 under-seat ported box for 05 GMC Sierra EXT. Cab
 

Hello everyone!

I recently just purchased an 05 gmc sierra extended cab and Im having a lot of trouble finding a 2 12 ported box that fits under the seat. Ive managed to find a sealed box with 8" mounting depth and 1.13 cu.ft per chamber, but Ive contacted the company several times about shipping to Canada and Ive yet to hear back from them.

I have 2 12" JL 12W3V3's.

If anyone in the GTA can build a box for something reasonable, that would be awesome, Im located in Ajax
