2007-2018 Jeep Wrangler JKU Unlimited Sub Box Double Ported

This box was designed for the use one shallow mount sub in a downfire box that keeps most of the storage area in the rear available. Storage space is always important to me to keep so keeping this design small was important. A taller version of this box could also be made for more bass and if you are using traditional subs and not shallow mount. Please select the version that is best for your needs or if there is something special you need feel free to ask. 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.

This is a ported subwoofer box. Ported subwoofer boxes are 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 as a sealed box, but there is double the bass of a sealed box with the same subs. A sealed subwoofer box has a tight and punchy bass that is more articulate and truer to the music with a more natural sound. If tight, punchy bass is what you want then our sealed box will be what you want.

This is our ported design. This design is for maximum airspace and the airspace of the box can be reduced if desired. Our ported boxes are designed according to your subwoofer’s specifications. No two boxes will really be alike. At checkout, there is a Comment box, please give us the model number of your subs and we will build the box as needed. We tend to tune our boxes deep, around 34-37hz. If you have any specific requests, please feel free to let us know.

This box is made of 3/4″ MDF and is fully carpeted in matching carpet. The nickel-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.
