Hey guys,

We recently had a guy want a custom fiberglass box for a 8 inch sub built to go under his 2001 Avalanche seat. Unfortunately he wrecked his truck and then left us with both the box and sub. The sub is brand new and only taken out of the box for fitting and pictures. The sub box was custom built to go under his rear bench seat. It is all fiberglass box with white primer currently on it. The box is not complete. The pictures below you can see tw imperfections where we had stopped work due to his situation.

I need to simply get my money worth back out of this sub and the box. I'm asking $220 for both shipped to your door. I can also paint this box for an extra $10 with a indigo blue color which he brought to me when we started this project.

I accept both Paypal and USPS MO.

Thanks,
Taylor

Im interested in the box itself. Will this fit under my 03 denali seat? What is the max mounting depth for the sub? What is the cu ft of the box?

Thanks!

Mounting depth is 5.5 inches. CU of the box is .5-.6 but any sub that requires .8CU runs flawlessly in this box. There are no air leaks at when I tried another sub in this box. If the rear seat is the same as a 01' Tahoe or Avalanche then yes it should.
