Flatwire

I point the speaker back to the back of my salon. They were put there by using a product called flatwire to run under the floor. I do not know if flatwire has been installed correctly, so I want to be able to verify whether or not the son of the speakers are properly labeled as left and right and if they can cross (short). I would do without executing on the receiver first, since the instructions warning that it could cause damage to the receiver.
Good ideas about testing this?
Thank you.

I doubt suggest investing in a digital multimeter. Get something that lets you check volts and continuity or resistance in ohms.

The first step is to set the meter to continuity. Make sure that the son at one end does not touch. Connect the probes of the device, one at each wire on the other side. If you read the continuity, it is a bit in the thread. If the meter has no continuity function, you can use the resistance function. Set the meter range or just below ohms (Îc) from self if it is. Repeat the same procedure as before. You should have an infinite resistance reading (the same meter reading to be seen with the son to touch anything.) If you show a bit of reading, there is a short. (Note: Do not touch the probe ends or son during these tests or the meter reading may be the resistance through your body)

There are two ways to test polarity. I like the idea of the battery displayed. Take the battery and connect it to one side of the speaker wire (one wire to the end suspected positive and one negative.) Adjust your meter to DC and son probe at the other end. A negative sign comes on reading if you have the negative probe touching the positive wire. I also like the idea of watching the movement speakers that you apply a small DC voltage. To do this, connect a speaker at one end of the wire. Then, on the other hand, hold the presumed positive end to positive end of the battery and the negative press on the negative side of the battery. Observe the speaker cone movement during this action. If the cone moves out from there, the polarity is correct. If it moves first then the polarity is reversed. Good luck.

Tester contiguity

set based on whether complete cones are breathing instead of on the cross so boboom

This trick is used by car-audio installers to verify that the President is left and which is right.

Simply connect the speakers to a son of 1.5V battery. If everything is OK, you should hear a beep!

If you have a voltmeter, connect a AA or AAA batteries at one end and measure the voltage (and polarity) on the other end. Repeat for each cable. Mark each cable and polarity.
If you do not have a voltmeter, using a loudspeaker, the cone is moving from one side or if the polarity is reversed, moving in the opposite direction.
