Any home theater receiver allows you to connect a minimum of five speakers, including a front left and right pair, a center channel speaker, and a surround pair. You can always add a subwoofer if desired. Some advanced receivers allow you to connect an additional one or two "back surround" speaker(s) for use with 6.1-channel sources such as DTS-ES or Dolby Digital EX-encoded DVDs.
For stereo listening, you can connect an "A" pair for the room where the stereo is located, and a "B" pair for another room (as long as your receiver has two sets of main speaker outputs). Hooking up even more pairs of stereo speakers is possible, but it requires an external speaker selector that both provides more speaker outputs and protects the receiver against low impedance loads.
Tip: Many receivers will not let you run the "B" and surround speaker outputs simultaneously.

some have suggested attaching 100 .02ohm speakers. makes it fun yo

Re: How many speakers

My 3802 7.1: is running 9 speakers , in the speaker settings i select "A+B" default is "A" , so if your looking for rear surround it works for me . I've always had Denon as my main unit so no comment on other companies .
Tip: If your looking for a new HDMI killer surround reciever "Onkyo" is setting the bar pretty high so watch out onkyousa.com, bring your credit card (lol)

If your looking for an owners manual www.brouchureworld.com this guy has everything you can think of and more .

I own a SA HE200, it has "overload" protection. If you drive it too loud into too low of a speaker impedence, it will display "overload " and switch it's speaker connections off. Turn it off, then it on & it will reset. panasonic recomends 6 ohms, with a speaker mode for less than 6 ohms, a "low impedence mode" it has. I have speakers conneted to all 6 channels, the fronts, huge 4 ohms, center 8 ohms, rear left & right 5 ohms & 4 ohmsper channel connected in paralel = to 3 ohms,and rear center 4 ohms. This receiver connected to all of these speakers works extremely well, with no problems of any kind. It has not been needed to use the low impedence function, and you can turn it up loud enough to cause ear damage without it distorting the sound, long before ever reaching "overload", which I have only had happen 2 times. The statement was a question, so this is experience input not a solution.
