These are regular speakers ? This is a mono public address amp and designed primarily to work with purpose built speakers that require the 25 and 70 volt power provided.

You might try putting a spare speaker (you can afford to damage) across the 4-16 ohm and com terminals and see what happens.

But I'd be inclined to contact the manufacturer for better advice than I can give:

If they are 8 ohm Hi Fi speakers one wire connects to 4-16 ohm and the other wire connects to com (thats two 8 ohm speakers, hooked in parallel, for a total load of 4 ohms).
If the speakers are small public address speakers, with transformers attached, they hook to 25v or 70V and com.
You have not described the speakers in detail.....but I can assume they are hi fi speakers.
