Multiple speakers in same outlet (by 2 users)

TECHMAN IS WRIGHT BUT IFF YOU MUST USE MORE SPEAKERS USE A 1 INTO 4 SWITCH BOX.
WHEN USEING A STEREO AMP YOU SHOULD ONLY USE 2 SPEAKERS FOR BEST SOUND.
REMEMBER WHEN YOU LISTEN TO A LIVE BAND THEY ARE IN FRONT OF YOU NOT AROUND YOU.

HOPE THIS IS HELPFUL.

CABLE GUY.

i have a similar issue...i have a decent sound system, mix and matched....by that i mean, i run a cable from my laptop, to a mixing board, then from there i run 2 cables to my stereo system, which is hooked to 2 speakers....basic....but i have 2 more speakers that the wires from each speaker are split to another 2 subwoofer enclosure...would 2 splitters do me fine if i do so decide to hook up the last combination to the stereo?

The suggestion is correct for Amps designed to run at 8 ohms. If you amp, like the Onkyo 8511 that I was attempting to search on, is capable of driving 4 ohms, then go for it.

I don't know how "Techman" got a "Guru" rating but his answer is completely stupid.

The manufacturer rates the speaker outputs for 8 ohms. Plenty of people have reported running 6 ohm speakers just fine. What few people realize is that this impedance rating is not fixed like a resistor, it changes based on frequency.

Anyway, all the rating means is that you have to keep the individual total speaker output rating near 8 ohms to avoid over or underloading the amplifier channel. You could put two 4 ohm speakers in series (some dual voicecoil subwoofers are manufactured this way on purpose), or two 16 ohm speakers in parallel. You could put four 2-ohm speakers in series, four 32 ohm speakers in parallel, two 2-ohm speakers in series with two 16 ohm speakers in parallel, etc etc etc. As long as the equivalent resistance presented to the speaker output is around 8 ohms.

Also if you underload (present more than 8 ohms) you won't "burn up" anything, you just won't develop the maximum volume potential of the amplifier out of the speakers.
