.....guys, I haven't posted really long up until this one, take it or leave it....
....how do you wire speakers in series?....simple....you take a single speaker wire FROM, the Positive, (+), amplifier-section Post, TO, the Negative, (-), post of the speaker....then attach a single speaker wire to the other post of the speaker, the Positive, (+), post of the speaker, and hold the second piece of wire straight up in the air....you can now go left, and return to the negative post of the amp section, and have completed one CURCUIT, or go on to the negative post of a second speaker, attach a single wire to it's other side, and have the same option concerning the wire leaving that speaker for either the third speaker, or a return to the negative post of the amp section to have completed ONE curcuit of two speakers wired in series...with me?....
.....you can take "every" 8 ohm speaker in the World, (remember, thats's an enclosure with multiple speaker elements and a crossover), and wire EVERY ONE of them in a SERIES configuration and ONLY present ONE 16 ohm load of resistance to an amplifier section, "IF", you've not completed the one curcuit by going to the amp negative terminal post until from the LAST speaker....whew....here's the theoretical part....the amplifier section should be able to produce sound from EVERY SPEAKER in that one curcuit and only see 16 ohms of resistance, and run cool....staggering thought......
.....try that paralleling, and you've got one ohm of resistance at the fourth pair of speaker terminals, and you're already past what your amp section can handle without achieving thermal cutout in minutes if not seconds....here's a hint....individual curcuit completion....at the end of four speakers paralleled, you have four curcuits of parallel, that are governed by the laws of paralleling which includes accumulation of completed circuits....now all 4 parallel curcuits represent 1 ohm since we're stacking individual curcuits and have gone accumulative by the laws of parallel....now, at this point, you can add one more speaker wired in one-deep series configuration, and bring the "overall" ohmage factor of five speakers on one amp section to "4"........1+1+1+1+16, which will be a total of 20....divide that by the number of speakers?....in this case yes, but you need to think in terms of the number of completed curcuits....you can add forty speakers wired in one-curcuit configuration on top of the four curcuits of parallel, and you would only have one circuit added, and we've established the one curcuit of series-wired speakers would represent ONE 16 ohm load of resistance to be averaged in with the other four curcuits of parallel....and guys, it wouldn't matter if ALL the wires were to two amp posts....add all the series, "CROSS-WIRED-LAND", haha, speakers you want with ALL of them wired to the posts and it don't matter....16 ohms of resistance from each completed curcuit....remember that parallels stack, and would have to be balanced out, only, with series curcuits....which brings me to,.....
.....I still say something is going on inside your surround receivers....you have two amp sections, with seven powered speakers....one of them is mono with one two-sided speaker wire, or at least, Danny's center-speaker only had one two-sided wire....
.....let's forget the center-speaker, and look at 6 others....if three 8 ohm speakers are being powered by one amp section and all are wired normally, which means three indiviual circuits of parallel on that amp section, that one amp section is now seeing two ohms of resistance....both amp sections are pushing three speakers, also....let's bring the center-speaker back into the mix, and hook it up at the amp section's posts, "normally", establishing a curcuit of parallel....do you see the problem at hand?....at least one of your amp sections just went to 1 ohm of resistance seen....1+1+1+1=4 divided by four curcuits....
.....and how "one" plus wire could be powered by "both", amp sections, is beyond me, but technology may have achieved that, and I am most curious how the center is powered....anyhow, at least one of your amp sections is now heating up toward thermal cutout seeing 1 ohm of resistance....
.....regular receivers used to be able to take 4-16 ohms of resistance seen, and at least one of your amp sections is now at one ohm of resistance....unless....you threw a series wiring curcuit somewhere in the mix....let's say your mids are wired in series one-deep....and let's say the center channel is being powered through technonogy through both amp sections....it would STILLl present ONE wiring curcuit to both amp sections, and that says fire and smoke, haha, this is not the way you want to strap your amp, haha....that's where I feel it is just one amp section being used for the center speaker....
....anyhow, let's say it is a parallel curcuit to both amp sections....you now have four curcuits to BOTH amp sections....BOTH amp sections are now seeing a 1 ohm load.....wire one of the curcuits in series, and you would THEN have 2+2+2+16=22 divided by four curcuits....5 and change....what?....what was that from the back of the room?....oh, ok....the guy who owns the hi-end audio repair shop has not sat at the workbench in probably 15 years....your surround designated speakers COULD have crossed-wiring upon arrival at the terminal posts of the surround section, "inside"....food for thought....
.....I ain't gonna' quit until I figure your surround receivers out, you bunch of smelly tin-eared Neandertholistic Heatherns....paw the ground twice if it fits.......
