In Reply to: connecting additional speakers to a 5.1 receiver posted by marcoangels on May 29, 2003 at 21:39:20:
Parallel will halve your impedance, serial will double it.Very low impedance could damage your amp, high shouldn't.
Getting it balanced and imaging properly may be the bigger issue.

Okay, sorry, let me re-phrase this dilemma....I have a Pioneer 5.1 receiver and purchased 2 additional speakers, thinking I could hook them up as additional L-R speakers to fill out the dead spots in my room. My old Sony receiver had a Speaker A and/or B switch, but this receiver doesn't. Because of the thickness of my 16 gauge wire, I cannot twist and connect the second speaker wire to my receiver, so I've opted to twist and connect via the speaker terminals...I've connected the L terminal of Lspeaker1 to the L terminal of Lspeaker2 and the same for the right speakers...will this damage my receiver's poweramp and/or, is there a better way to connect the 2 sets of L-R speakers? The reason I've added the 2 extra speakers is because of my room's odd dimensions, I can get a wider L-R separation...Johnny
If I understand correctly, this represents how you have it wired:BreceivrR

that is parallel, and halving you impedence. This is probably working your receiver too hard.Try wiring the speakers like this:
|---BreceivrR---|

Might be easier on the amp but it will be 100 times more painfull to the EAR. Do you work for Bose or something? This is how the 901's are wired. Driving speakers off the output of speakers is insane. Stop screwing with the series wiring while your ears still function.
I don't work for bose, and I'm not screwing with series wiring.I was just trying to clarify what I understood as a suggestion from another post. I certainly wouldn't recommend driving speakers in series - or parallel for that matter.
All I said was that it would work the amp less.
Ok, well my ASCII diagram keeps getting mutilated by the website software.Try this:
Go from receiver+ to speakera+
From speakera- to speakerb+
and from speakerb- receiver-
