With a simple flashlight battery.Connect wires to the speaker then breifly touch the wires to the battery and watch the speaker.If you have positive to positive and negative to negative the speaker will "push outwards" if you have it reversed it will "suck inwards"
It depends what you mean by 'polarity'.
For a d.c. circuit, 'polarity' means correctly identifying the positive and negative conductors. You can use a d.c. voltmeter (or multimeter set to measure d.c. voltage), taking care to observe its polarity markings. If the instrument's needle moves upscale, then the polarity of the supply matches the polarity of the instrument.
For an a.c. circuit, 'polarity' means that the line and neutral conductors are correctly identified. To do this, you need to use an a.c. voltmeter (or a multimeter set to read a.c. voltage). With one of the voltmeter's terminals connected to earth (ground), the other terminal is connected to the supply connections. A deflection indicates a line conductor, whereas no deflection indicates the neutral conductor. Always check that the voltmeter is working properly before conducting the test.
Also, be aware that a.c. mains (supply) voltages represent a serious shock hazard, so do not conduct a polarity test if you do not know how to protect yourself against this hazard.

How can you do the polarity test of a switch?
A 'polarity test', as it applies to a switch, is performed to confirm that the switch is located in the line conductor and not in the neutral conductor.
What is used to check for line voltage sags?
just a digital voltage meter measure at the origin, and then at the end of line
What is the equipment required to do a CT polarity test?
You shouldn't need to perform a polarity test on a CT, as its terminals are normally identified with polarity markings.
Which current is having high polarity?
ac(Alternating Current ) has the high polarity.
Does thermistor have polarity?
No, they have no polarity. They are just like a resistor in terms of polarity, and they allow to measure temperatures because their resistance varies with temperature in a predictable way.
How does a speaker polarity work?
a speaker polarity is sub mainframe of the ................................
How do you test speaker wire polarity?
Observe polarity and touch a 1.5 volt battery to the terminals and note the direction the speaker cone moves.
Can speaker reverse polarity damage speakers?
No. Reversing the polarity does not damage the speaker. The only issue in connecting it backwards in a stereo setup is the speaker cones will not be moving in sync with each other, so stereo imaging and bass response will suffer.
What is the speaker dimensions for a 1993 cougar xr7?
check out www.crutchfield.com/ they will tell u speaker size as well as what will fit the car
How can you determine the positive and negative terminals on a car speakers?
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
Why does my car stereo turn on but not make any sound?
Check that the 'mute' button hasn't been pressed. Check the speaker connections, especially in the doors. I have known the amplifier to shut down, because one speaker was shorted out with water.
Why do you have a popping sound in your speakers?
If you have installed new speakers you may have the wires reversed causing reverse polarity.Good way to check polarity touch the speaker wires momentarily to a small battery If the cone pushes OUT good,if the cone pulls in you have reverse polarity-not good <> reverse wires.If they are original speakers the speakers may be defective.
What does pularity mean?
Check your spelling - is the word you are requesting: polarity?
How can one install the Bluetooth car speaker?
There is a very easy way for one to install the Bluetooth car speaker. One can install the Bluetooth car speaker by plugging the device into the car's built-in stereo system.
Does a speaker blow if you connect it directly to the battery?
i wanna know if you can really blow a car speaker i wanna know if you can really blow a car speaker
What is the polarity of car grounding?
The car grounding system is typically connected to the negative terminal of the car's battery, which is considered the ground or negative terminal. This means that the polarity of car grounding is negative.
How do you connect new 6x9 rear speakers to the factory wiring in a 1990 Mercury Topaz?
First of all you will need to snip the factory connector off near the speaker(s) you intend to replace. Then it is a matter of trial and error to get the correct polarity. If the polarity is reversed, you will still get sound out of the speaker, however, the tone coming out of the speaker will be higher (little to no bass). If that happens, reverse the wires and mount the speakers.
