Proper placement of the subwoofer box in your car will ensure that you get good bass response from your car audio system. If the box is placed poorly, the bass will sound muddled. Regardless, adding a sub box is a critical requirement for getting good sound from a car stereo. There are many ways to mount the box, and your choice will be partly dictated by your vehicle type.
Things You'll Need
- Sub box
- Heavy duty Velcro
- Tie straps/bungee cords
- Wood screws
Decide where to place the subwoofer box before mounting it. This will take some experimentation. Some common choices include up against the rear seat, with the speakers firing towards the rear of the vehicle, or against the back, with the speakers firing towards the seat. If your vehicle is a hatchback, try placing the subwoofer against the back of the car with the speakers firing up towards the ceiling.
Cut strips of heavy duty Velcro (two inch wide) and place the hook side of the Velcro on the subwoofer and the loop side of the Velcro on the floor of the trunk. Slide the subwoofer enclosure in place. This method is preferred by people who may want to pull their sub out for parties, or who want to move it around.
Cut a piece of wood to the exact width of your trunk and place it under the carpet in the trunk. Screw the subwoofer enclosure to the piece of wood using wood screws. By making the wood the exact width of your trunk, you ensure it won't move.
Use L-brackets to get the most secure placement of the subwoofer in the trunk. Attach one side of the L-bracket to the box and one side to the trunk itself (either the floor, the rear trunk wall or the side wall). Before doing this, make sure that you won't be drilling into any wires or a gas line.
