Looking for an amplifier

[Willard_Bones]

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!

I got this to attach 2 wharfdale speakers to my jukebox pc.  https://www.amazon.co.uk/LEPY-2024A-Plus-Amplifier/dp/B00SATAEEA/ref=sr_1_fkmr1_1?ie=UTF8&qid=1513634372&sr=8-1-fkmr1&keywords=Levy+amplifier

Ideally only 1 unit will ever be on at once right?

JROK ouput, convert to line level:

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...
