2009-2018 Dodge Ram Crew Cab Sub Box Single Low Passenger Side


2009-2018 Dodge Ram Crew Cab Sub Box

We started building our Dodge 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 Dodge 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 a Single Low version of our 2009-up Dodge Ram Crew Cab sub box. This is what we call the Single Low Passenger side box since the box fits only under the Passenger Side back 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 Single Low Passenger box has around .8cuft total of airspace. 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 Dodge Ram trucks have cargo bins under the rear seat floor mats. The Quad Cab Dodge Ram trucks do not.

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!
