2019 Ram 5th Gen Quad Cab 2500/3500 HD Sub Box Dual Low


2019 Ram 5th Gen Quad Cab 2500/3500 HD Sub Box Dual Low

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.


This is the Dual Low version of our 2019 and Up Ram 2500/3500 HD Quad Cab sub box. This is the full width subwoofer box version for this truck and takes up the entire cargo space under the rear seat. This version of the box does not require the rear seat to be lifted, but seat spacers could be used to lift the seat if more clearance is desired. Installation does require the removal of the fold out cargo trays or the hard storage compartment covers for the box to drop into place.

The Dual Low boxes have 1.6cuft total of airspace and share airspace with a brace in the middle. We used to do the subs in separate airspace but the odd and irregular bottom of the box made it difficult to make the subs airspace exactly the same. We found that sharing the airspace made them perform much better. On the Low boxes we do not include nickle plated spring loaded speaker terminals on the back of the box, we only drill and run speaker wire and seal the hole up. The only place to put a speaker terminal would be on top of the box and I prefer not to see it and ruin the factory look of these boxes. If you really want a terminal on top we can install them for you.

Mounting depth on these boxes is around 7.5″ for 10s and 6.75″ for 12s. All measurements are based off of a 6″ diameter magnet. The depth doesn’t change for a 10, but with 12s, they hit the sloped back wall of the box if the magnet is too big. For example, a sub 12″ sub with a 7″ magnet may only be able to be around 6.25″ deep, where a 5″ magnet sub could be 7.25″.

When ordered, please let us know if your truck has the split 60/40 rear seat or if it is a single bench seat.

Also let us know the year model and carpet color description as there are different colors available depending on the year of the truck. We have good matches for all carpet colors except for the Chocolate Brown that is being used on the newer Rams. Every dark brown we have is a terrible match and we don’t want to ship out something that does not look good. We usually do either a tan to match the bottom of the seat or just do black.

And 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.

These boxes do not require a 1.5″ seat lift but they can be added if more clearance is desired. Please select the options for your specific truck so that we can ship out the correct parts that you need. The seat lift does retain full functionality of the rear seat and still allows the seat back to lock into place. If the seat is raised more than 1.5″ the seat back will not function properly.

Crew Cab Ram trucks have cargo bins under the rear seat floor mats. The Quad Cab Ram trucks do not.

This is a sealed box. We do not offer a dual subwoofer ported sub box for this truck, and we have many reasons why. Most ported boxes will be around double the size of their sealed versions, or close to, if you are expecting it to perform the way that a traditional properly tuned and designed ported box should perform. Since we cannot magically double the available airspace under the back seat of these trucks, it is best to stick with sealed. We know that some competitors offer ported boxes for these trucks, but just because you can do it, doesn’t mean that you should do it.

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!
