So, we added a buck converter to the input which drops the voltage to 12.9v to charge the battery and power the speaker. This buck module was simply hot glued to to the bottom of the board.
A toggle switch was added to isolate the battery to prevent parasitic draining of the battery over timedisconnect the stereo from the power inputs. This decreases the "standby" load to 15mA as opposed to 30mA.
An added bonus is that it is easier to operate the toggle and toggling on always turns on the unit.
And voila, all done and running on battery and it sounds amazing!
