2 Ways to Secure Truck Sub Boxes

Truck sub boxes are an excellent way to ensure that your stereo delivers the full range of music as recorded on your media of choice and that you will be able to experience the full punch of your favorite music. A stereo isn’t really complete until you are able to feel the rumble of the really low end bass in your stomach. You’ve got a ready-made opening for the head unit, or compact disc player, as well as the speakers in the dash and the door panels. You’ve placed your amplifiers and crossover network under the passenger seat to get them out of the way but allow ready access to them. But you’re not sure how or where to mount your subwoofer box. There are a number of different ways to secure your sub box in your truck, depending on how permanent you want the installation to be or look, or if you may want to be able to move the box around. This article will address 2 methods, securing the box to the back wall of the cab in a semi-permanent installation, and securing the box inside the void in the seatback of the rear seat in a more temporary installation.

Permanent Installation Behind Seat Back on Back Wall

If you decide on this method, the truck sub boxes will hang on the back wall of the passenger compartment behind the rear seat. You will need to affix 4 `L’ brackets with 4 holes to the sub boxes. You will need 1 L-bracket on each corner. Affix the brackets to the sub boxes with 1/2 inch drywall or wood screws. To attach the boxes to the back wall, you will need 1/2 inch self-tapping or self-drilling screws. Use a level after installing the first self-drilling screw to make sure the sub boxes are installed perfectly level. After the sub boxes are securely mounted, you will want to route the wires under panels and kick plates to the amplifier powering the subwoofers.

Temporary Installation in Rear Seat Rear Void

If you choose this more temporary installation method, you will need a package of cable ties or zip ties. Attach an L-bracket with 2 holes to each corner of the sub box. Place the box into the seat rear void and attach to the seat frame by running a zip or cable tie to the seat frame. Use 2 ties per corner and route them at angles to each other to ensure that the speaker box is securely tied to the frame. You should use a minimum of 8 cable ties to accomplish this.

No matter which method you choose, you can finish this project in less than 1 hour. Be sure to route speaker wires so they won’t interfere with people getting in and out of the truck.
