Speaker wire polarity.
I know this one will be too easy for some of you but I'm a newbie so
stay with me. I am changing speakers in my car and I wish to verify the polarity of the speaker wires themselves. I don't need advice in determining the polarity of the speakers, just the wires that lead to the speakers. Thanks in Advance! |

I'll guess that you want to identify the wires because they are not marked or coded in any way. If you have a voltmeter, you can connect a AA cell at one end and then measure the dc polarity at the other end. |

I'll guess that you want to identify the wires because they are not marked or coded in any way. If you have a voltmeter, you can connect a AA cell at one end and then measure the dc polarity at the other end. Unless someone has fitted new wires that are identical, there must be some identifying mark(s) on them. Are they individual wires, or a piece of twin ? If twin, there will usually be a stripe on one wire, or text printed along the sleeve, or a difference in the sleeve profile between top and bottom, or even the strands inside may be different colours - gold in one conductor, silver in the other. If it really is two absolutely identical wires, then you will need to get at both ends, and use a battery and meter as suggested by the other poster. Alternatively, you can connect to the speakers with no regard to polarity, then use at 1.5v cell at the far end. The speaker cone will move either out or in. So long as you then pick one wire to arbitrarily be "+", and arrange for the same direction of cone movement on the other speaker, to arrive at a similar arbitrary "+", then your speakers will end up correctly in phase with one another.

The speaker terminals are marked + and - . If that's the only speaker, then "polarity" is irrelevant. If you're replacing one speaker in a stereo system, then connect it consistent with the other one. That means determining the polarity of the other speaker, which you can do with a 1.5 volt battery.

At least in home speakers do. If my car speakers use AC then polarity should mean very little, as in I won't fry anything???? That's my main worry, destruction thru reverse polarity. For the speakers in question I am using the striped wire to connect to the minus terminals on the new 5 1/14 inch speakers. They sound fine and a lot better than the old ones. |

If they are side by side, then they need to be in-phase. And Charles is right - if you get it wrong all those lovely bass notes will be reduced.

Why would you want them out of phase if on facing doors? Explain.
I personally would make sure the polarities are the same on both (in phase) since this is the way the music was originally recorded to be played back. Bob wrote in message ps.com...

If they are facing each other and in phase the sound waves create a dead zone where they cancel out. If you reverse one side they are aiding each other. When they are on the same wall the effect is reversed. What is real fun is when someone puts speakers along all four walls for paging, and you can't hear anything in the center of the room. Sometimes you want a dead zone, and if you can place the phase the speakers properly it is amazing. I installed a sound system in a high school football stadium about 30 years ago. They told me they wanted to be able to use a live microphone from goal post to goal post for the band. It worked so well that the coaches from visiting teams never failed to complain, "My boys can't hear your PA system!" I would jusT smile and tell them to "Teach your boys to play ball, not to listen to the game". Losing coaches have no sense of humor, but the school was thrilled with the way it worked. -- Service to my country? Been there, Done that, and I've got my DD214 to prove it. Member of DAV #85.

This is absolutely correct. There is no issue with " + " or " - ". The terminals could be arbitrarily called " OMO " and " DAZ ". Provided that there is no grounding at the speaker end, radio " + " could happily be connected to speaker " - " and vice versa. For stereo, they should both be connected the same way round because of phase cancellation in the bass, as already pointed out, but that is the only caveat. If someone is bringing in a radio with blown outputs, unless one terminal of his speakers is grounded, then reversed connections is most certainly not the reason. If, however, he is feeding the high level inputs of one of those nonsense 4 gigawatt amps, then there may just be an issue, but even those usually have floating inputs.

where the solid or striped wire goes on that speaker, + or -. Connect new speaker accordingly. If the new speaker is not maked +, then connect a 1.5v cell to the speaker.

Thanks in Advance! _____________ Simple way to determine polarity for any speaks: Grab a 9-volt battery(or even a bulky 6-V lantern deal). Place one speaker lead to the + and one to the - terminal. Watch - or have someone else watch if speaker is too far away - the movement of the cone driver as you remove and re-touch the + terminal. If the cone pushes up(or out as the case may be) the polarity, or "direction of motion" is positive. You want all your speakers to move in the positive direction - that is, into the passenger cabin. regards, -CC |

I also installed a handful of Quad 8 track tape players in cars, back in the '70s. Car radios and home stereos were part of the commercial sound division for the shop I worked for.

Speaker wire polarity.
Come on guys, chill.
Civility in debate is a desirable attribute. I know that is perhaps heresy on a usenet group but most readers do beleive it. No one at this point can even sort out what your points were. All that it has become is a ****ing match. Drop it it you don't have some points to make. Speaker phasing is just not that hard to figure out, and certainly not worth all the fuss.

I'd suggest you check maker's installations before sounding off. And then refund all the money you ripped off from your customers. It's quite easy to test your theory at home by turning your Hi-Fi speakers so they face one another. And place your head between them to see if the sound disappears (with a mono signal). -- *A closed mouth gathers no feet.* Dave Plowman London SW To e-mail, change noise into sound. |

Speaker wire polarity.
_____________ Simple way to determine polarity for any speaks: Grab a 9-volt battery(or even a bulky 6-V lantern deal). Place one speaker lead to the + and one to the - terminal. Watch - or have someone else watch if speaker is too far away - the movement of the cone driver as you remove and re-touch the + terminal. If the cone pushes up(or out as the case may be) the polarity, or "direction of motion" is positive. You want all your speakers to move in the positive direction - that is, into the passenger cabin. regards, -CC So far so good, allow me to restate the situation: 1996 Dodge Caravan, replacing front speakers only at this time. Original speakers are unmarked, new ones are marked + and - . So far so good. Am now about to attach wires. Do the solid color wires go to the pos terminals and the striped wires go to the neg terminals? Just wondering ......... |

Do the solid color wires go to the pos terminals and the striped wires go to the neg terminals? Just wondering ......... Let's just say " yes ". It ain't gonna go bang, as you were worried about, as long as one of the terminals is not connected to the frame of the speaker, and the speaker is not also screwed direct to the metal of the door - just to be clear, that's BOTH conditions together. It's probably gonna sound fine. All of the car radios I've ever seen, with speakers in the doors, have been factory wired in phase, but if you feel that you are getting echo-y, thin sound, just reverse one of them. Again, no bangs to be had. Just as an aside. If the sound cancels in the middle of the vehicle, how would you know ?? All of the standard road vehicles that I've seen have seats offset to the sides ... Arfa |

It's most unusual for speakers not to be marked in some way. Are the terminals the same size? Car speakers in this neck of the woods have usually got one 1/8th and one 3/16th spade terminals. But if not other posts here give the method of checking using a AA cell, etc. There are conventions for speaker wiring colours in cars but it's a question of knowing which one your maker followed - if any.;-) -- *Always drink upstream from the herd * Dave Plowman London SW To e-mail, change noise into sound. |
