copper is positive
Depending on colours of course black is usually negative and the other colour (generally red but depends) is positive. Get a D-cell Battery. Now get two pieces of speaker wire. hold one wire on the positive terminal of the battery and hold the other on the negative side of the battery. touch the wires to the positive and negative posts on the speaker. if the cone moves out ward the positive and negative are correct if it moves inward then the positive and negative are reversed (out of phase.) this simple test will allow you to see which terminal is which.

A negative divided by a positive is negative. A negative divided by a negative is positive. A positive divided by a positive is positive. A positive divided by a negative is negative.

The positive speaker wire is a solid color, your negative wire should have a stripe on it.
In a DC circuit, the black wire is typically the negative (-) wire and the white wire is the positive (+) wire. To ensure proper connection, always check the specific wiring instructions for the radar system you are using.
Generally, white wires are positive. Red is usually negative. However, the construction of the electrical device could be different. It is best to check the instructions.
