2007-2018 Jeep Wrangler JKU Unlimited Sub Box Large Downfire Sealed

This Jeep Wrangler Unlimited JKU sub box was designed for those who want big bass and aren’t concerned with loosing cargo space.

This design has 3.66cuft of airspace and over 12″ of mounting depth, which allows for a ton of options for your subwoofers, to get you exactly the big bass that you are after. The subs mounting surface is 2 3/4″ from the floor, which will allow for a lot of travel from some big subwoofer. A downfire box works best in an open air vehicle like a Jeep because the loading effect of the downfire design helps to get a little more output since there is no cabin gain in an open air vehicle like this.

The box is a pretty snug fit between the fenders in the back, so it works best to come in from the back doors. If you’re worried about security, you can put screws in the legs from the back fender wells.

This is a sealed subwoofer box. A sealed subwoofer box has a tight and punchy bass that is more articulate and more true to the music with a more natural sound. For customers who want louder deeper bass with the lower bass more pronounced. Because of the ported design, the bass will not be as tight and punchy, but there is double the bass of a sealed box with the same subs. If big bass is what you want then our ported box will be what you want.

This box is made out of 3/4″ MDF and is fully carpeted in matching carpet. The nickle plated spring loaded speaker terminals are mounted on the back of the box and the speaker wires are soldered on for a solid and reliable connection.
