So a 2 channel triway capable amp can run two speakers and a single sub. How?
Is there a special way to wire the amp? Are there three sets of speaker terminals? How would the power go? If it is 100x2 wrms would the speakers get that and the sub get 200 wrms? I know nothing about triway and it seems like a very economical way of running a front stage and a sub off of one amp.
I realize the draw backs would be non-fade-ability because the sub would be on the same input as the speakers.
Anyone who knows please respond.

I could be wrong but i think that the power would be spit in half. Half for the sub and half for the speaks. Example:
200wrms amp would give 50rms to each speaker and 100wrms to the sub. Assuming that you have the correct load.

Wow, tri-way. I haven't thought about tri-way configurations for a good 7-8 years. 
Power just got so cheap everyone could afford a separate amp. Well that OR everyone seemed to forget that your front end needs good power too 
Anyway - with the trip down memory lane done...
You wire the woofer mono with a lowpass passive crossover. Then you wire the highs normally in stereo but with a highpass passive crossover. This can be as simple as an 8mh coil for the woofer and a pair of 200uf caps for the stereo pair. In fact a number of companies in the early 90s (such as Alpine) even sold a stereo in / tri-way out passive [img]graemlins/thumb.gif[/img] I used to hotrod them for guys by increasing the slope on the lowpass.

As for power - the woofer sees the rated mono power and the highs see the rated stereo power.
Give it a try, all that can happen is if you play something with heavy duty bottom end it can starve the top end and clip it out, making it sound bad and giving your tweeties a hard time.

Tri-amp is what you would do if you're crazy like me. Even crazier if you were to bridge all channels. [img]graemlins/freak.gif[/img] If it weren't for space limitations, I'd run 6 amps just for the front stage, one for each component. Too bad, I'm only using four. [img]tongue.gif[/img]
