Which wire is positive/negative?
1469171
There is no positive/negative wire. One end goes into the outlet and the other goes into the device.

Typically the white or dash-dot wire is positive and the unmarked black one is negative. As to the plug itself, the center pin is positive and the shield is negative. Of course, it is always best to test with a volt meter but this is standard electrical wire code.

There is one hot wire and one negative wire. I wired mine to a toggle switch on my boat and they work excellent!

black wire is a ground.. common sense says black is ALMOST ALWAYS negative/ground.

yes there are two wires one positive and one negative. The wires are relatively short so you may have to add some length to them. I soldered a longer piece to them and put them on my camper about two foot above the normal signal lights. They really make a difference.

You either connect POSITIVE to the POSITIVE and the NEGATIVE to the NEGATIVE. Or you can BRIDGE them together the TWO POSITIVES together and the TWO NEGATIVES together. Both will work either way.

the wire with the dean connector that is included is color coded red/black for the polarity. output is the load dean socket. source is the input dean socket. it's clearly labeled in the watt meter case where you plug in the dean connector.

With a standard 12v DC adapter. Look on the PCB and you will see a + and - sign indicating the polarity.

The Positive lead is clearly marked if you have the one with the rubber MC3 connectors, The Female MC3 (the one with the hole inside if looking at the face of the connector) is the Positive Wire. If you look at the rubber boot it has a + molded into it

Middle is positive or "hot" wire. The 2 ends are the negatives and brass is ground.

It doesn't matter as long as you make sure negative is connected to negative and positive is connected to positive. Same copper wire, just different plastic coatings. If it helps to keep everything wiring correctly for you, then use the blue stripe for all of your negative connections. You have made a good buy. Excellent speaker wire!

It's never a good idea to try to trust wire insulation color as a determination of polarity unless you have a datasheet that clearly states the color and polarity. I always test power supply outputs with a meter before connecting them.

N is for neutral (white wire) and L is line or hot (black wire). Wiring it wrong can be a shock hazard.

You only use one wire to this one & another wire to the other. Positive & negative ... 2 channel,2 speakers

One wire goes to positive, but the other wire just needs to be grounded to your vehicle, not the negative wire, this should fix the problem.

It's for you to know how you wire your system. It's doesn't matter which one you use for positive or negative. I use white to signal I hooked it up to positive.

The center wire should be Positive. Sorry that's the best I can tell you, it's been way too long since I installed mine.

red wire goes to pos. black wire to neg. yellow goes right side of shunt white wire goes to left side, ok now the negative wire from the battery, goes to the left side of shunt . now the right side neg wire goes to the load green wire goes to out put side or left side of inver pass the shunt.that it .GOOD LUCK....
