2007-2018 Jeep Wrangler JKU Unlimited Shallow Downfire Sub Box Ported


2007-2018 Jeep Wrangler JKU Unlimited Shallow Downfire Sub Box Ported

The Jeep Wrangler Unlimited, or JKU, offers a lot more cargo room than the standard 2-door model, giving lots of options for carrying cargo. But, if you want big bass but don’t want to give up your cargo space, what are your options? This is it!

This box was designed for the use with shallow mount subs in a downfire box that keeps the majority of the storage area in the rear available. Storage space is always important to me to keep so keeping this design small was important. The box fits from the back of the back seat to where the cargo floor lifts up, so that cargo bin is still accessible. The overall height of the box is only 6″, so there isn’t much cargo space lost and you can still stack your gear and groceries on top of the box without hurting it.

This design has 1.76cuft box for a pair of shallow subs, with a shallow mounting depth of 4 1/2″, or 5 1/4″ if you use our metal back plates. It was designed for the Pioneer shallow 10s, which are awesome in it, but there are some other subs out there that will work in it as well. You could do a few shallow 8s, or one shallow 12″ ported. 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 more true 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.

Our ported design is for maximum airspace and the airspace of the box can be reduced if desired. Our ported boxes are designed according to your subwoofers 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 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.
