Portable tpa3116d2 speakers

Try marine speakers in an ammo can. With careful switch, jack and speaker selection, the results are weatherproof and water tight. Ammo cans are very rugged, extremely durable and when braced properly, can sound surprisingly good. Then for batteries, use drill driver battery packs. They are the best choice when you balance cost, performance, convenience and safety.
The end result is actually quite astounding, both in terms of sound quality and output.
 
Ammo Can Boomboxes

For instance, a very powerful, very rugged, high resolution boombox can be built that weighs less than nine pounds. Total.
Even the heaviest weighs less than twenty pounds and go just about anywhere. Some folks take them when traveling in their carry on baggage.
The hardest part is deciding which color to paint the Ammo Box.
