Our new Radiator Boom Box used (2) 5.25″ drivers for the mids and highs and (4) 5.25″ passive radiators for bass.
Power is supplied by the 10ah LiFePO4 battery pushing the JBL 4 channel amp. EQ is by Planet Audio.

Mike has some thoughts
Mike played around with the Bike Party system from 11-12-20 and shared the following thoughts.

How many amps?
I would be lost without my Burning Man friends. Special thanks go to Erich Rienecker from Pongo Lounge and Ilya Polyakov of Icarus.

3 things
We need three things:
1) An on/off button to cut power.
2) A battery monitor that will cut power when the battery declines to 12v or 50% (for lead-acid).
