It's a cheap Parts Express amplifier and I posted the model number and other details earlier in this thread. Replacing or modifying the power supply to send more power to the audio amplifier would probably require modifying the amplifier. Have you tried using the speakers that other people are using in the Blast City? I like how my Blast City sounds but if I were to do it again I would try an easier solution first.

my issue is that my PS has crapped out. I recapped and still dead. I found a replacement psu I want to try, but I'm working out the internal wiring now. I want to keep the wiring in the stick ps box so I'm making a harness to convert everything to the original connections. the amp is the only place I'm struggling on
The Blast City amp is only for amplifying the line level stereo output from JVS hardware (or something like Mister or a console etc). If you only plan to use JAMMA hardware then you don't need an amplifier. If you plan to use something other than JAMMA then you'll need to figure out how to power the stock amplifier from your new power supply, or you can copy what I did with a Part's Express amplifier. I posted the full wiring diagram in a previous post in this thread. The Blast City manual also has a wiring diagram.
