No sound from Jamma Speakers?
lettuce:
Have just fired up my Jamma Cabinet for the first, after fitting a PC with J-PAC etc, everything worked ok, the monitor was my main worry but that was great, but i didnt get any sound from the fitted cab speakers! Theres 3 in total, one left, right, and a centre one thats placed in a box, i guess it acts as a sub, should i be getting sound from these speakers by just connecting the jamma connection to the J-PAC, or do i need to do some re-wiring?

The speakers are expecting an amplified audio signal. They might be receiving it, but it'll be so low it's not moving the cone. You'll need an audio amp of some sort if you plan on using the cab's original speakers.

So whats the easiest ways to get sound, just plug speakers in the PC sound card and use them?. Why do some people insist on using the Cabinet speakers with an amp, why not just use the PCs Sound card with PC speakers, surley that would be the easiest route to take?

PC speakers are easier, since they are internally amplified - they usually have to plug in to power as well as the pc. Usually, you can get better sound from the cab speakers with a good car amp - but that is more of a pain. If you get a good set of pc speakers with a sub, you can most likely get better sound than what you'd get from the built in ones, especially since they are probably getting on in years, and are most likely cracked and not performing up to new specs...

What you just said doesn't make sense. In either situation your sound would have to come from a PC sound card. The difference is between amplified and non-amplified speakers. It's not that illogical really, if you consider that even stereo systems use unamplified speakers .
The problem here stems from the fact that over the years, sound-card manufacturers stopped making cards with built-in amps, because you get much better sound, and a whole lot less interference if you use proper external amplification.
So, "why do some people insist on using the Cabinet speakers with an amp?" -- For authenticity and so that their JAMMA cabs remain JAMMA cabs? I don't know... In the end it's your choice. Plenty of people have just used PC speakers.
