2019-up Ram 5th Gen Quad Cab 1500 Sub Box Upfire Single X-Large Ported, Seat Lift

We started building our Ram sub boxes around 2006 because of the lack of high quality solutions that we saw on the market. With our local success of our boxes, we decided to sell them online in 2010 and we haven’t been able to keep up since. We have shipped our Ram subwoofer boxes all over North American, including Hawaii and Alaska, a ton of them to Canada, and even recently shipped one all the way to Norway. The quality speaks for itself and in all the years we have been shipping these we have never had to warranty one.


The New 5th Generation Ram Quad Cab trucks are super limited on space. The back seat is a lot smaller than the Crew Cabs in this generation of Rams. So much so, that it made it much more difficult to fit a decent subwoofer box under the back seat. This is the design that we were came up with for a single ported 12. The enclosure goes straight across the front of the box to gain a little more airspace. Because of this it limits leg room for the middle seat against the console.

The box is built in layers to get the profile to the seat and the floor and we ended up with 2.27cuft of airspace. This enclosure is made to work with a 1.5″ seat spacer and all hardware is included with the enclosure for your truck. This is perfect for a single 10″ or 12″ subwoofer.

Mounting depth on these boxes is 8 1/4″, 9″ with our optional metal back plates. All measurements are based off of a 6″ diameter magnet. The depth doesn’t change for a 8 or 10s. This enclosure is for 8″ or 10″ subwoofers.

This is a ported subwoofer enclosure. Ported subwoofer enclosures 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 typically double the bass of a sealed box with the same subs and power. 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 designs will be what you want.

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 enclosure as needed. We tend to tune our boxes low, around 34-37hz. If you have any specific requests, please feel free to let us know.

All the enclosures include nickel plated spring loaded speaker terminals on the back of the box.

Please include the type of sub being used so that we can make sure it will fit before it is built and so that the hole cut for the subwoofer is the correct size.

All of our Ram Boxes are built by hand on order. Each box is build to your specific needs and finished as specified to match your interior and your subwoofers.

Made in America with American materials. Nothing but the best!
