Project Description:
Portable DIY BT boombox housed in a hard plastic tool box. The design was built around the Wondom AA-AC111

Design Goals:
I wanted to build a portable BT boombox for a friend that owns a tile contracting company. The idea was to create a portable boombox he could take to job sites that would be durable and rechargeable for greater portability.

Driver Selection:
Dayton Audio ND90 8ohm 3-1/2″ full range driver

Enclosure Design:
Repurposed hard plastic tool box

Tips & Tricks:
The Parts Express support team was super helpful. They helped me calculate the proper bass port design and the issue with the bad aux cable.

Conclusion:
The amplifier has decent output. The BT range is not as
good as the specs say. The aux cable included with the board was wired incorrectly. I had to cut the wires and re-wire in the correct pinout to the connecter.

About the Designer:
I’ve been tinkering with electronics for the past 10 years. I design and build coustom effect pedals for guitar and bass, as well as low watt guitar amplifiers. I love DIY and re-proposing old radios and storage objects for audio electronic projects.. I’m not an experienced speaker builder but I’m working on it.
