you can take a 9v batt and tap it to your speaker wire. Hold one wire to a terminal on the 9v and tap the other on and off the opposite terminal if the speaker pulls in wrong polarity if the speaker pushes out its correct. Then just make note of which one was on which terminal of 9v and your good to go

How do you wire stereo speakers?

The new speakers come with un-stripped copper wires..... you need a pair of wire strippers.... i put in kenwood speakers and the size of the wire was 14 somethin. you would need to get a wire diagram for you car/truck to see the colors of the positive and negative wires. then look on the aftermarket speaker box to see which wire is negative and which one is positive.... After you would do all this, just match up negative to negative and positive to positive. simple as that. I'd recommend wire nutting the wires or electrical taping them... but DO NOT put all four wires together. that will mess your speakers' sound up completely. wire nut the positives together and then wire nut the negatives together.


What is meaning of series and parallel connection?

If you connect a device like a LED or a speaker in series, that means that you connect the positive terminal of one speaker/LED to the negative terminal of the other speaker/LED and apply the audio/voltage to the remaining positive and negative terminals. When you connect devices this way, that means that both of the speakers/LEDs are getting the exact same current, but different voltages depending on the position in the parallel circuit. If you connect a device in parallel, then that means that the device's positive and negative terminals are connected to the other device's positive and negative terminals, and then voltage is applied to the positive and negative terminals of the devices respectively. This means that the devices are getting the same voltage but the current varies and is highest at the positive connection and lowest at the negative connection. (The voltage that each device is getting is determined quite easily by doing the sum 'input voltage / number of devices'.)


How do you a car radio that only two speakers wires a ground an a positive connection?

That would be a mono radio, usually found in older cars. You may connect 2 speakers, in parallel, but you will have no balance control. Simply wire positive to positive, and negative to negative of both speakers.


Which wires are negative and positive to the rear stock speakers for 2006 Chevy Malibu?

Dark blue is positive and light blue negative on right side and brown positive and yellow negative on the left.


What is positive and negative for speakers?

There are no polarity on any single speaker. If 2 or more speakers are to be connected, the way they should be connected is in parallel, so that when one membrane is going out, the others does so too. And not going in the wrong direction. That is why most speakers have a red dot on one of the terminals. Just to show their way of how the coil is set up. <><><>


How do you determine positive and negative on a speaker terminal that's unmarked?

doesn't make a difference as long as both speakers are wired the same. If they are wired incorrectly, you'll lose some bass when the speakers are placed face to face- all you have to do is reverse the wires on one set of speakers


In regards to speakers is the gold wire positive and the silver wire negative?

Yes


My home theatre speakers have grey and white wires which is positive and which is negative?

It does not matter, just make sure all the speakers are wired the same. I would make the GREY Negative.


Trying to install Clarion MD stereo for Peugeot 205 What is the colour of negative wiring from in car speakers?

the negative wiring for the speakers is the same colour as the positive but with a black line going down it


What are the colors for positive and negative on the speakers of a 1995 Cavalier?

The voltage in speaker wire is too small to cause harm. Plug the two wires in. If the speakers work the wires are correct. If the speaker doesn't work try them the other way. ANSWER voltage does not cause harm no matter how high. amperage is what causes harm. speakers will work like a light bulb either way. positive to negative or negative to positive. with sub-woofer you can tell if it is right, the sub should pull inward on deep base . I believe cavalier rear speakers are hooked in series positive in one speaker, negative of that speaker to positive of the other speaker, and neg of that speaker back to stereo


What is out of phase for a speaker?

In general, speakers have two connections, and it is important to connect them the "same way" to the amplifier. (Amps also have pairs of output terminals.) We usually designate the terminals of the speaker as positive and negative. (Outputs of amps are usually designated the same way.) It is important to connecteach positive speaker terminal to the positive output of the amp for a given channel, and each negative speaker terminal to the negative output of the amp for a given channel. This way the speakers will be connected in phase. It is possible to reverse all of the connections and not have problems, but it is critical that speakers be connected in phase. Speakers do not become out of phase or change phase. When they are constructed, their operation is fixed and will not vary during their lifetime. A given polarity of a wave, either positive- or negative-going, will always cause the speaker to move in the same given direction.


How do you use 16 ohm monitor speakers with an 8 ohm powered mixer?

Just use it like an 8 ohm speaker or else connect two 16 ohm speakers in parallel to form an 8 ohm load. Parallel is positive to positive and negative to negative.
