I need help finding an amplifier. I have an arcade cabinet with a twin system: Raspberry Pi and JROK.
The RPi has stereo line-out sound.
The JROK outputs speaker-level mono.
I would like to have an amp that could output the JROK signal to two speakers. And have the RPi as a second source.
Ideally, switch automatically to whichever input is active.
The speakers are Polk Audio 5-inch automotive. I think amplifier output of 20 watts would be plenty.
What advice can you guys give me?
Thanks!

Ideally only 1 unit will ever be on at once right?
Cheap amp board:

or
Build your own:

Then make a Y cable. Wire the JROK's mono to both L and R lines of the amp's input. And wire the rPi's out to the same amp's input.
Jenky... should work...
