  1. High Quality Construction Sub Box

    Posted by Kyle on 23rd Feb 2015

    I own a 2500HD Crew Cab Chevy and ordered this product. The box arrived in great shape and it was clear that this box was a solid design and construction. The 10inch sub sounds great and the amp rack allows for a clean installation of all the components. One very small issue I am having is my rear seat does not go down enough to fully lock into place thus creating a small vibration noise from the lock mechanism itself while driving. I have not had to time to trouble shoot it yet, however, if there are any recommendations on how to solve this small issue while still keeping the entire box under the seat, I will be all ears.

    Overall, great box, great design and I will order again from this company.

  2. Awesome enclosure

    Posted by Keith on 13th Jul 2014

    Couldn't have found a better fitting box. Fits under my back seat without the need for any adjustments, barely even notice its there (except for the thump). All around great product.

  3. Sweet Box

    Posted by Mike Koss on 27th Sep 2013

    Very well made box and fits the truck perfect. I asked for additional depth for my particular sub and they made it happen. The back seat in my crew cab doesn't go down all the way but close enough that whoever sits back there wouldn't know the difference.

We build each sub box and ship within 3-10 business days excluding weekends.
