I replaced an older A-Trend sealed box with this ported Fox Acoustics box and it made a huge difference with my JL 10W3 (4 ohm) driven by a JL XD600 (400w RMS into 4 ohms) in my 4th Gen Ram. It hits several Hz deeper, higher decibel SPL, yet still gives the same punchy impact with mid bass kick. The fit is a little tight with the included lifting brackets...you may want to go with a slightly higher spacer with longer bolts, especially if you go with a high excursion sub. Overall though, the build quality is excellent, true 3/4" very dense MDF with a double baffle with an expertly applied bed liner finish. I highly recommend this sub box!
I was skeptical of the box due to the size restrictions under the seat. However, the Fox Box exceeded my expectations in every way from fit and finish. I installed a Sundown SA 10 and it added a great amount of bass. Don’t hesitate and get one for your Ram. I researched for several months before buying and must say it’s the best out there.
I never thought I would get this kind of sound quality out of a single 10” sub. This box is very well built and sounds amazing! Worth every penny
Box is built very well very pleased with my purchase
Fit and finish is on point, sounds great and it much more cost efficient than any other custom box that I've found. Completely satisfied.
