[tested] A small 40W mono amplifier, 18V-26V supply voltage (no -26V needed) just add a 24V powersupply or a car battery (also 24V not 12V ;D) The Main chip (tpa3106d) needs no additional cooling, the heat dissispation into the PCB ist more than enough even in hot surroundings. Audio input is in the upper left, V+ upper right, GND bottom left output two large connectors in the middle of the right side. The two jumpers are for gain selection.
