One of the reviewers mentioned that to get 8 Ohms / speaker you need to have speakers connected to all of the outputs. Is that correct?

I went through a steep and maybe incomplete learning curve when I wanted to add multiple speaker pairs to my setup but I do not believe you have to have speakers to all of the inputs for 8 ohm output. This switch is auto impedance matching. My system is 4 ohm amplifier and I've had 1, 2, 3 and 4 pairs of speakers connected at various times and have never had 6 pairs, the switch has worked great and I use it all the time when I am at home. One thing I would caution on is that while description says that you can use two sources at the same time I've found that you get bleeding from one source to the other side.

My understanding is that the you do not. You can have one set of speakers hooked up if you want. I have four sets of speakers connected at various volumes and they sound great.

This amp is stable to a 2 ohm load in a stereo configuration and 4 ohm load bridged. With four speakers with four ohm voice coils it can be done, even with 8 ohm coils but it will put out less power that way. Take two speakers positives and connect to one positive output on the amp and do the same with the negative speaker wires to the negative amp output. This is called hooking your speakers up in parallel, it halves the ohms so the amp will see only 2 ohms. Conversely if you hook up speaker one's positive wire to the amp positive output, then hook that speakers negative to speaker two's positive and then speaker two's negative back to the negative output on the amp is called hooking them up in series. It doubles the ohm load and the amp would see an 8 ohm load from two 4 ohm speakers and put out even less power/noise. This bit of knowledge is needed to know what impedance speakers you need to buy for the amp you want.

Should be 8 ohms...not going to see lower then that unless you get the really high end audio stuff. Typically...even still 8 ohms is about the standard.

My speakers have the near same 87dB, 8 Ohm, with 16G wire to them with 25 foot of wire so I hooked them together and ran it to one speaker and it sounded just the same. I think 16G wire will be just fine for your situation.

No I have not, but if it's a 4ohm rated amp I wonder if there will be adequate power to sufficiently power them (depending on your needs), as these are 8 ohm speakers.

Yes the MB42X are 4-8ohm speakers but most 8 ohm receivers can power a pair of these so you're fine

Thanks H. Choi. I notice from the manual that it says use 8 - 16 ohms below the speaker terminals, but one doesn't have to believe everything they tell you. :-)

Correct, the 75W output rating applies to 4 ohm speakers. At 8 ohms it's less. Manufacturer's data provided in a tnt-audio web review indicated 50W for each of two speakers at 8 ohms:Power Rating STEREO: 50wpc @ 8ohms, 75wpc @ 4ohms, 0.01% THD, full bandwidth MONO: 150watts @ 8ohms

I tried an old set of (I believe) 8 ohm speakers on the front right, left, and center channels and notice a marked improvement in sound quality. Do you have more information on this? Will the amp be damaged? Any idea where I can get better quality 3 ohm speakers?

It depends on the speakers, most consumer speakers are 8 ohm and would be connected to the 8 ohm outputs. Some commercial speakers are wired in series and are equipped with a 70 volt transformer and would use the 70 volt connection. Most speakers have the impedance printed on them.

Yes, you're right. If your speakers are 8 ohm, then you should connect the red wire to "8" and the black wire to "0".

correct, you can connect up to 4 ohms, but you have to be aware with your .saludos speakers rms.

Mr. Garrett - Technically this is a 2-channel Amp. You can easily wire 2 pairs of speakers to it however, and alternate between the two or run them simultaneously. I have run 4 6 ohm speakers this way without issue and it played plenty loud. I imagine you could easily run up to 3-4 pairs of 8 ohm speakers in parallel this way, or more if you ran them in series. But it would be safer to make sure that you used the same speaker if you were going to start hooking up tons of them (because the impedance of each would be about the same)!If you wanted to run multiple speakers off the amp, like the other responder, you could do it, provided that you keep the impedance above the 4 ohm minimum.

I ended not using amp, but power seems fine for typical announcement speakers. You need to E-mail Pyle at their web site, but considerations are how many Ohms are the speakers (typically 8 but some variation typically OK), and look up serial vs parallel hookup. Running all the + and - for each speaker to the same + or - jack seems the way to go. Try, before installing, put on one speaker, turn on. Put on second, turn on, etc. It's not like you can blow a speaker if you start with the volume low, and turn up. Also the best way to make sure all speakers and wires work before install. Make sure you use a good gague spool of wire, and that you get the connections good - loose conncections and damaged wires are hard to find after install. PS 50w for voice seems plenty! PPS if you get a Hummmmm it would would be problem with input or amp grounding problem.

All speakers can be connected in series but you will have to add the impedance of the speakers that are in series. In this case, 4 ohms + 4 ohms = 12 ohms. The new impedance load for the amplifier would now be 8 ohms. You can easily check this stuff on google.

You haven't provided all the necessary information to receive a worthy answer. We understand you want to power a pair of dual 15" speakers at 8 Ohms, but that's all we know. Complete your research by finding out the power handling ability and capacity of the speakers. Then, look again at the outputs that the amp is capable of. Your answer is then looking right back at you. I assure you this: Relying upon a bunch of people you do not know for answers to questions like this is going to come at a cost. You have no idea that they know anything about which they speak.

Sorry! This question exceeds my pay grade. I've always used only 4 ohm, only 8 ohm or switchable 4 to 8 ohm speakers together.
