1-8 Hours

Project Cost:

$100 – $500

Project Description:

Basic ammo can using the 2×30 watt kit.

Design Goals:

Making a going away gift for a Marine who is going to another base. We wanted something other than a plaque and wanted the gift to be something he would enjoy. I added corner guards for a more rugged look and laser etched ” Parris Island” and “We Make Marines” on the lid.

Driver Selection:

Part #: 300-7301 ammo box kit Dayton Radio 3″ full range drivers

Enclosure Design:

It’s a M242 ammo can for 5.56 rounds

Enclosure Assembly:

I used a tungsten carbide 3″ hole saw for the speaker holes and an angle grinder to cut the hole for the control panel. Also used a bigger Bluetooth antenna routed through a hole to the outside to extend coverage. I used sound dampening adhesive rubber to minimize the metal reverberation. 80mm fan guards worked great as speaker grills with a bit of bending at the connection holes

Crossover Design:

None

Conclusion:

Sounds better than expected for an untuned cabinet. I’m certain the Marine will be happy with the gift. It was a fun, easy project.
