Amp with speaker INPUTS?? Please explain!

So, I was browsing an amplifier manual, as one does, and the diagram shows four spring clips (R+ R- L+ L-) labeled Speaker IN. (I couldn’t figure out the image hosting thing, otherwise I’d post pics. It’s an AudioSource Amp 300, and the manual is short and easy to find.) I’m not familiar with component connections beyond a couple pairs of speakers and maybe an EQ. But this puzzles me. Can someone please explain when you’d use this? The short “explanation” In the manual is woefully inadequate. 
 

I’m especially interested to know if speakers are at the other end of the wires that connect here. I mean, that would make no sense since speakers don’t send anything that direction, right?

Around this time Carver was selling the idea that too much power was not enough, so these amps were on the leading edge of audiophiles attempting to up their wattage.

Thank you for the info. Just one more question: If those receivers didn’t have a pre-out, what output did they use to feed the speaker in? Those speaker in jacks take bare stripped wires. Was there a similar pair of spring clips on the receiver labeled “speaker out?”

Thanks for the detailed answer. But that’s not the amp model I’m asking about. It doesn’t even have the speaker inputs I’m referring to.

So what? You asked a question and he was kind enough to get you a valid and helpful answer. Don't see why you would chide someone that is trying to help.
