Candy Cab Owners - Driving Speakers with Jamma Games?

Just wondering what you guys are using to drive both speakers when using Jamma games? I think some of the cabs come with amps to help switch between stereo and mono, but what about ones that didn't. I've got to wire a cab up and am trying not to engineer my own solution.
 
The majority of cabinets come wired dual mono without an amp of any kind.

There are a few exceptions. The capcom impress for example has a qsound stereo amp. There is a connector you move over for normal mono games. At this point the signal is bypassing the amp and just passing through a volume pot. No amplification other than what the board puts out.

What cabinet do you have?
 
Joy-Ro 19, but the previous owner removed the power supply assembly which also contained the amp, Volume control and service switches. So, I get to wire mine from the ground up. The Joy-Ro doesn't seem to be sought after, but I thought it was kinda cool and I like that it had a smaller monitor in it.

I'd love to just pick up an assembly from another Candy Cab and throw it in, but nothing is really coming up in a few searches.

For the impress, which after a quick google looks like it would have a nice assembly I could throw in, when it is in mono mode is it driving one speaker of both. I'm only playing Jamma games in my cab and want to drive both speakers.
 
Dual mono, meaning both speakers are receiving the same channel. Typically speaking this is how most candy cabs are wired. Neo geos in the other hand are usually wired for stereo since that is the boards native sound output.

Right, but that's using the amps that come with the cabs. They aren't running the speakers in series or parallel are they?
 
Again, most of these cabinets do not have amps. The new astro city for example runs two 4 ohm speakers in series for dual mono. It gets routed to the power supply only to pass through a sound pot.

You should be able to splice into the jamma harness and run the sound from the board to a mini-amp (cheap on eBay) and from mini-amp to the speakers.

That's what I did on my new astro city.
