All,
I tried wiring up a mini-stereo plug (ring+tip) to the 2 wires that carry audio to the speakers in my SmashTV cabinet. However, I get no sound.
The image below shows the back of the speakers in the cab.

This did not seem to work. Any suggestions? Do I need an amp? If so, suggestions?

You need some kind of amplifier. Maybe something like this. (https://www.amazon.com/gp/product/B007TUSXEY/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1)

If you are connected to a pc, it is unamplified.

Back in the day we'd just hack up some pc speakers, but thanks to the internet you can just buy stuff like this:

Remember, as-is arcade speakers are pretty crappy so unless you are going to change them out there really isn't any need to buy anything fancy.

I used this one https://www.amazon.com/gp/product/B01N1UHTU1/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 (https://www.amazon.com/gp/product/B01N1UHTU1/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)
paired with this power supply https://www.amazon.com/gp/product/B018X975QG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 (https://www.amazon.com/gp/product/B018X975QG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)
in a pair of desk speakers and a set of big bookshelf speakers that I built.
The 24V power supply gets more out of the amp than some of the cheaper 12v ones that come as part of a bundle.
I think technically the specs on the TI amp chip says it can draw more than 3A, but I tested the amp on a bench power supply before settling on this power supply.
I don't remember the exact current draw, but 3A was more than enough.
