I checked in the specs of the manual here. page 6. They quote it as being suitable for 4-8 ohm AMPLIFIERS. but do not mention the actual impedance. I would expect from that that the speakers must be close to 8 ohms, as you they would not advise you to connect a 4 ohm speaker to an 8 ohm output stage, as likely damage could result. If you had a multi meter, you could do a DC resistance check of the speaker, this is generally very close to the impedance. happy to talk to you more about it.

    I turned in the two 151 SE speakers because my ohm check had open circuits for both but these new ones are just the same. Using the volt meter I get just the same readings on these and when I connect up the speaker to the output per the spec I only can get clicking when changing the volumn. No sound just clicking.

My Bose SA3 2 channel amp keeps blowing when I raise the volume with non-bose speakers, why is this happening?

Could be the impedence of the speakers that you're connecting. The bose amp was designed to drive 8 ohm speakers.

How to hook speakers up to a realistic mpa-40

The MPA-40 is a mono public address amp. So it has one speaker output. You select the appropriate socket to suite the speaker type. The 4/8/16 Ohm outs are for various tpyes of Hi-Fi speaker. The 70 Volt is used for muzak in shopping centres, restaurants, and waiting rooms.


If you have a pair of 8 ohm Hi-Fi speakers, you can diasy chain the connections and then use the Com and the 16 Ohm connection.

Daisy chain means you take the wires from a pair of speakers. Connect together the wires going to red on one speaker and black on the other. This now leaves you with two wires going to the other red and black terminals on the speakers, but the ends in your hand are not connected to anything yet. Plug the black in to COM. Plug the red in to 16 Ohm.

The sound from the speakers won't be stereo. It will be mono because that's all the amp outputs. But both speakers will work so long as they're functioning units.

If you have two 4 Ohm home theater speakers then you can do the same trick. 4 + 4 makes an 8 Ohm load. Connect the red to the 8 Ohm output.

Don't be tempted to try to connect to multiple terminals. The amp isn't powerful enough to to run more that one speaker chain.

Hope this helps

How to equalize extra speakers?

The only thing you can do to equalize those speakers. Make sure that you have them in faze. + to + and - to - and left to left and right to right. Make sure that your speaker can handle the ohms. (the same ohms) for example If your amp is rated to handle 8 ohms then your speakers should have 8 ohms. The speaker wattage should also be abit more than what your amp can produce. Distortion is your worst killer of speakers.

Hello, I have inherited a McIntosh MC-7270 amp, and plan on wiring it to my two Bose 201s to test before selling. I need to know how to properly wire the speakers to the amp. The rear of the amp looks...

Well what you are dealing with is a HI-FI tube amplifier. The reason it has COM, 1, 2, 4 and 8 are because it does not have a transistor driven output. It has a transformer coupled output. The 1,2,4,and 8 are the different taps of the transformer in order to impedance match your load (speaker) with the tube power section. This amp is 270 per channel and your speakers are only suggested to 120Watts. You would use the Negative to the common terminal and the plus to your 8 ohm terminal on the Amp. This is a great amp, you should keep this and not sell it.

I have a TOA 301 15W amp and a Bose 151 environmental speaker(40w 4 ohms). I do not have a manual for the amp and wish to connect the speaker as a small PA . My concern is that the output I think I should...

Don't worry about the 7.7 volts. Just connect between COM and 4 ohms and you'll be fine. I didn't find a 301 part number related to a 15w amplifier, but I did find a BG series (115 130) of 15 watt amps manual

How many watts in 8 ohms

Ohms is an impedance, they call it resistance. You have to hook up 8 ohm speakers to the 8 ohm terminals on your device. Some speakers are 4 ohms, and may not be able to handle the power if hooked to 8 ohm terminals, so be sure you have what they call an "impedance" match.
Watts, by the way, is what they measure Power by, and P=EI (Power equals voltage times current).

Bose SA-3 amp and a non bose sub.. I keep blowing the amp..

How many ohms is your sub? The SA 3 Amp can only handle speaker(s) 6 ohms and greater. A lot of subs, as I understand, are 2 and 4 ohms typically. If yours is 2 or 4 ohms, then that explains it. The speaker would be "straining" your amplifier and blowing it.

Realistic MPA-35 amp by Radio Shack

It's not that this amp isn't like "newer amps" with + and - terminals, it's that this amp is made for public-address system use. This kind of amp is used in a store, for instance, to pump background music through speakers all over the place. The terminals you connect to are determined by total impedance of the speaker configuration used.

Most single speakers, or the two- or three-way cabinets for home stereo systems, are 8 ohms. If you're connecting a single speaker you use the "common" and "8 ohm" terminals on the rear panel. With multiple speakers, you need to figure out the total impedance and use the appropriate terminal. In series, impedances add. Two 8 ohm speakers in series would total 16 ohms, so you use the common and 16 ohm terminals. In parallel, the total impedance drops. Two 8 ohm speakers in parallel total only 4 ohms. You need to figure the total impedance of the speaker configuration and connect accordingly. Too great of a mismatch will damage the amp or speakers or both.

You might be able to find the manual for this amp on Radio Shack's website. Here's a link to the manual for the model MPA-40 which should have similar output terminals. The basic information about figuring out total impedance and general use of PA amps applies to your amp as well.

Bose amplifier does not work with a 6 speaker selector

your wall speakers may not be connected.... disconnect each speaker from the selector box and test with a small AAA battery to see if they are connected by putting the battery between each speaker's wires , you will hear it crackle ,then gradually connect each wall speaker onto the speaker connector box . If the first set does not work i suggest there may be a problem with your speaker selector box . Good luck
