Exisiting Cabinet speaker

[wrighty]

For my mame project I am about to start installing the audio side. My golden tee machine already has speakers in it How can I use these with my PC? I have read the build your own arcade machine book but it seems to be orientated around a build from scratch rather than having an existing cab!

Cheers!

Generally your PC will have a "line out" which is an un-amplified audio signal. So you need to amplify the signal to deliver some decent volume to drive the existing speakers.

This can be done a number of different ways.

Here are a few options:

1) Hack a set of amplified computer speakers. The wires that would normally attach to the satellite speakers would get wired into the existing cabinet speakers.

2) Use a dedicated home audio amplifier. This could be an old (or new) stereo receiver or a small dedicated amp (such as the one kevinp pointed out here: http://forum.arcadecontrols.com/index.php?topic=79015.0)

3) Car stereo amp. These generally run on 12v which can be tapped from your computer's power supply. They are readily available and can be very inexpensive.

Good luck!
