Turbo Out Run sound help

[spalt]

Hi everyone!  Long time, first time, etc.  I just purchased my first two arcade cabinets for my basement, and there's an issue with Turbo Outrun:  the sound is busted.  Actually, to be more precice, if I stick my ear very very close to the speaker I can hear the music and sound, it's just very quiet.  I tried the obvious:  switched speakers, switched L/R, but no luck.  I figured something might be up with the amplifier, so I attached an old computer speaker w/ built-in amplifier thinking that might be able to be a quick-and-dirty workaround, but that didnt seem to work either.  Any suggestions would be appreciated!

this sounds really daft but have tried turning up the volume control?

Yeah.... turn it up....geez.   

Actually, I agree in a sense, find the volume pot and fiddle with it.
It may be bad also.
But you "have" sound, so I would assume that the amplifier is functioning otherwise you probably wouldn't have anything at all.

For the regular Outrun (which is upgradeable to Turbo Outrun I believe) there is a sound test mode, and it can also adjust the balance. You might check in the service menus for something like that on yours.

Did try the volume, thanks

Anyway problem fixed, or at least, hacked to my liking sufficiently...  It was definitely the amp causing the problem, as when I unplugged the wire going from the main board to the amp and ran a wire from there to my amplified speakers I got perfect sound.  So what I did was throw my computer speakers up behind the marquee, ran the speaker power line out the back, and now no one will ever know the difference (probably).
