Quickly build a portable Bluetooth speaker with the Urban Tactical speaker kit. All the components conveniently fit into a 50 caliber style ammo box. You may have one of these metal ammo boxes lying around the house or plastic versions are available at most hardware stores. All you have to do is drill two 4" holes and cut out a 3-2/3" x 2-3/4" hole. All the wires plug directly into the boards without any soldering. Screw down the speakers with the included screws and attach the speaker wires and you're ready to impress friends with a great sounding, 100W portable Bluetooth speaker. The on board Bluetooth antenna delivers up to 50 ft. of range. If you're mounting the board in a metal enclosure connect an external antenna (sold separately) to the antenna jack on the board. Batteries not included. Add sound damping material (sold separately) to make it sound even better.

Note: Crossover components may be substituted with parts of equal or higher quality depending on available inventory.
