Thank you for answer.
I'll see if I still have the service manual. I'm not sure if it covered that. You could pull one out and put a digital multi meter on it so see where they spec at. If you are also looking at speakers, make sure to check what the sensitivity of them are. Speaker specs usually state for example 89db @ 1watt. The higher the db the more efficient the speaker. Also, you could find yourself going in reverse as the speaker enclosure is usually designed around the speakers theil-small parameters. So just throwing a speaker in there could have less headroom or have a skewed EQ.
