Stereo speaker problem

I have a 4 speakers system. One speaker shuts the receiver off when I power it up. I've isolated it to one speaker by disconnecting all speakers and trying one at a time. I then swapped the wires for this speaker from red to black terminal and this had no effect. It still turns the receiver off. Do you have any suggestions?

The speaker is bad. The receiver detects a shorted condition and shuts off to prevent the amp section from damage. Replace the speaker or the wires. Something is shorted.

The physical fit is simple. They are designed to stack. How you drive them though is a different matter.

Depending on the vintage these are either an 8 Ohm load or a 4 Ohm load to the amp. Each pair needs to be connected to the appropriate driver/controller box for it's impedance. IOW, you need to run two sets of power amps, two controllers, and then two pairs of speakers.

BTW, just adding more speakers to a stereo power amp (or two monos) won't make the system appreciably louder. All you are doing is diluting the power output of the amps between four speakers rather than two. More speakers, sure. But each one now receives half the power compared to running 1 pair..

Hi, I have a Cinemate Bose Speaker Series II System and I would like to know if I could connect Stereo Jacks from the Bose Module to a Stereo Receiver without damaging the speakers or subwoofer, and if...

That would depend on the unnamed receiver.

Most receivers have standard analog stereo outputs labeled Tape Out or something similar. You can use them as sources for stereo analog material but their outputs are not variable or under any receiver sound controls so the Bose volume will need to be adjusted. If using a Tape Output, do not select the output for listening on the receiver. THAT would disconnect the other source you're listening to.

If your receiver has a Pre-Out for the desired channels, they ARE under internal sound controls so you could set and forget the Bose volume.

0ne speaker has no sound wiring is ok and stereo is ok

Make and Model? has many manuals and the troubleshooting sections have recommendations for this.

Or, you could swap the speaker with one that works to decide if it's a speaker or amp (channel) problem. Then isolate the wiring.

If it's internal to the receiver or the speaker you'll need a tech to look at it for a fix.

Hi i have a older jvc stereo and i have klh audio system model 9706 satellite and i do not know how to do the wiring i can get three spks workig but thats it can u help me do the wireing my jvc has 4 spk...

You can use 4 speakers. Connect 2 speakers to the A system of the JVC and the other 2 to the B system. Then select in JVC the A+B speakers position. As your receiver is stereo, this is the way you could best distribute the sound. However, if you have only 3 speakers, it would be dangerous to try wiring the third one without changing the whole impedance. So you may use 2 speakers.

Hello Audio Gurus..This is my 1st time on here.. I always loved music and I have decided to raise the bar a little in terms of sound considering that I enjoy listening to music more then 2 hrs a day.. I...

No, the CV speakers are very efficient speakers. That means they create a lot of volume for the amount of power. I will start by saying you will be relatively happy but not blown away.

The HK is an alright HT receiver (very new and feature loaded). It makes a rather weak stereo receiver for it is made for a home theater environment. If you only have a pair of speakers (optimal for music listening) then you have paid for a bunch of other channels that will remain dormant. You would be best off to get a very high-power stereo receiver or integrated amp instead of your HK.

CV speakers are built to blast, but they sounds pretty good at the same time.

Feel free to ask me any audio related question, I've worked in the industry for a good part of my life.

Samsung HT Z320 sub and center speakers dont work

Set the system to the FM receiver/ Tuner Option. Select the 'mode" button on the remote control. Set the system to the Dolby PL II option. This will engage all the speakers. I had the same issue and this fixed the problem!

Best amplifier for bose 901 VI speakers

By all-in-one amplifier that handles the surround I think you mean all-in-one receiver or preamp. Amps are just big dumb muscular power supplies for speakers.

The source control and digital decoding could be handled by a modern AV receiver with multichannel analog outputs for driving separate amps or you could get a digital AV preamplifier/control unit functionally like this Adcom. Prepare for sticker shock.

Understand that EACH PAIR of Bose 901's will require its own DEDICATED two channels of amplification AND someplace to jack in its Active Equalizer - between the line level source and the power amp.

Conventional speakers can probably run off the receiver's amplifiers since they don't/can't/must not have the Bose Active EQ in line with them.

Having a single pair of 901's plus a passive subwoofer or two in the same room for accurate 6- or 7.1 surround would require at least four stereo amps or some combination that adds up to 8 channels.

In my own system I have a Pioneer VSX-36TX Receiver (with 5 potential channels of amplification for Left, Right, Center, two Surrounds) doing light duty as the control and routing center but ONLY driving the Center (two Kenwood 777's) and Surround speakers (Bose 301's). I have a Carver 5-channel amp pushing the Bose 901 Front speakers (100Wx2), two dbx Subwoofers (110Wx1) and the Bose 301 Rear Surround speakers (60Wx1).

You could probably get by with a powerful 2-, 3- or 4-channel amplifier to push the 901's and subwoofer(s) as I did. It's the cheapest way out if you get a decent AV receiver. Once you set up the levels and delays the receiver does all the thinking and controlling for you.

Hook up to stereo

That's a very generic question, but generally you should find on the back of your speakers a pair of connectors either marked (+) and (-) or colored in Red and Black (or both designations). Similarly in the back of your receiver you'll find two sets of these, one for the Right channel and the other for Left. All you need to do is to hook up your Left speaker to the Left Channel in the receiver with proper polarity (red to red and black to black, or (+) to (+) and (-) to (-)) and do the same for Left.
Now you can use speciallized speaker cable (available from Radio Shack etc.) or simple flexible stranded copper electrical cable from a Hardware store. The gauge (size) of cable depends on your receiver's / speaker's maximum output power (watts) and the estimated length of cable run depending on the positions of your equipment. Generally : a 100W set with a run of 20 meters (60ft) at 8 ohms will need no more than 12AWG (4 cable. But you can supply your exact info and we'll do the calc. for you.

Stereo System Doesn't Make Sound

Tell your son not to play with your stereo.
Sorry that was a bit blunt. The Speakers from a bose system generally run at about 4 ohms of resistance, your sherwood amplier is spitting the dummy because it can't handle that sort of a load. get some proper speakers and make sure that they are connected up properly, and that none of the cables are touching.
