CX7110L-800 Fits 2007-13 Chevrolet/GMC Extended Cab and 2014 and Up Double Cab

As you might have noticed, ProBox does not offer an unloaded sealed 2-10” or sealed 2-12” downfire — and for good reason. During the developmental stages, we built multiple configurations, and none of them met our expectations or standards of sound quality. We decided not to put an inferior product on the market.

Some of you may have a 2-10” or 2-12” enclosure, and are not very happy with the quality of the sound. Stop wasting your money — we’ve been there, done that.

The new body Chevy Extended Cab presents a bit of a challenge due to the constant changes in floor pan elevation. Our layered design follows the contours of the floor on both the left and right sides of the truck, maximizing the air space in the enclosure and yielding phenomenal results that exceed a generic downfire box with two generic/universal run-of-the-mill subs.

Don’t waste your time and money on anything else. The CX7110L-800 by ProBox is by far the best design on the market. It’s truly a work of art that you have to hear to believe. Nothing Rocks Like a ProBox!

Assembled in the USA with parts from China. Availability, pricing, descriptions and specifications subject to change without notice.

Enclosures Not Sold Empty.
