I got a temporary amp to test the stock 3″ speakers that came with the Sega Astro City and I was not impressed at all. In fact, it sounded terrible. So I decided to find some inexpensive replacements and turned to Parts-Express for that. Here are a few different models I am looking at.
The amp I got to drive these speakers is a Sega Naomi Amp.
I know the replacements need to be at the least 3″ and 4 Ohm. The stock speakers are 15 Watt RMS speakers.
