Adding Second Speaker in SEGA

asked Jun 25, 2018 by txmarsh
I have a Sega Starship Troopers that was designed to have only 1 backbox speaker (was a cost saving measure by SEGA).  If I add a second speaker to the backbox will it automatically work with the 2.1 cable and the PInsound+ or do I need to change something in the sound files?

I confirm it will work with a 2.1 wiring cable.

Note that the original sounds are in mono and adding an extra speakers will not "magically" switch the original sounds to stereo. But then you can create your own sound track with files in stereo.

The Sega amps are only 4 ohm capable. If you are using standard car audio 4 ohm speakers, these need to be wired in series. Do not just run the wires also over to the new speaker. If you do that you will be putting too much strain and heat on the audio amp and will blow it eventually if not soon. The proper way to wire these in series would be to desolder and move the - wire from the original speaker to the - on the new speaker. Then run a new wire from the - on the original to the + on the new speaker. Now everything is wired safely.

Thanks for the details Rudolf.

I think the question was about using a PinSound+ board. And in this case there is absolutely no problem wiring the missing left speaker.
