Great Sub Box

Good quality item and exactly as described. The bedliner adds a great look as well as some extra durability, especially for the price.

Great build quality!

[This review was collected as part of a promotion.] Item is super sturdy, this is no cheap build sub box, has some good weight showing it's quality, it is rhino lined with some great texture that'll keep box from moving around, has pre installed wire connectors to help with easy installation, cut outs at the bottom to be able to install some nice deep subwoofers, would definitely recommend for someone that wants to install a system under their back seat, color will match black carpet, cut out for individual fold up seat.

Total surprise

I placed my order wondering if the 2 day shipping would actually work out. It was delivered as promised and not damaged by the shipper. It fits perfect under the rear seat and the sound is amazing. I'm glad I searched online because I saved quite a bit instead of buying locally. Hit that checkout button, you won't be disappointed.
