So you want to save some money and work on your own car, but you aren’t sure how to tell the positive and negative speaker wires apart. Identifying the positive speaker wire versus the negative speaker wire in a car can be a bit tricky, but with some basic knowledge and a few simple tools, it can be done with ease. Here are some steps to follow to identify the positive and negative speaker wire in your car.
Step 1 to find the positive and negative speaker terminals :
Step 1: Turn off the car – Before starting the process, make sure that the car is turned off and the keys are removed from the ignition. This will prevent any electrical accidents or shocks from happening.
Step 2: Locate the speakers
The first step in identifying the positive and negative speaker wires is to locate the speakers in your car. Usually, the speakers are located in the front and rear doors of the car, in the dashboard or the rear parcel shelf.

Step 3: Inspect the wires
Once you have located the speakers, you will need to inspect the wires. In most cases, the positive speaker wire is marked with a “+” sign or is colored red, while the negative speaker wire is marked with a “-” sign or is colored black.
Step 4: Check the stereo system
If the wires are not marked or colored, you will need to check your car’s stereo system. Most stereos have a positive wire and a negative wire marked on the back of the stereo. You can use a manual or check online for the stereo’s wiring diagram to identify the positive and negative wires.
Step 5: Use a multimeter
If the wires are not marked or colored, and you cannot locate the stereo’s wiring diagram, you can use a multimeter to identify the positive and negative wires. Set the multimeter to measure voltage, and connect the positive and negative leads of the multimeter to the wires. If the reading is positive, then that wire is the positive wire. If the reading is negative, then that wire is the negative wire.
This is one of the best methods to identify positive and negative speaker terminals.
Step 6: Use a battery
Another way to identify the positive and negative wires is to use a 1.5-volt battery. Take a AA battery and connect one end of a wire to the positive terminal and the other end to the speaker wire. Take another wire and connect one end to the negative terminal of the battery and the other end to the other speaker wire. If you hear a pop or a clicking sound, then you have connected the wires correctly. If not, switch the wires around and try again.
Step 7: Mark the wires
Once you have identified the positive and negative wires, it is important to mark them. You can use colored tape or markers to mark the wires for future reference. This will help you avoid confusion when you want to connect or disconnect the speakers.
Conclusion:
Identifying the positive and negative speaker wire in your car may seem like a daunting task, but with a few basic tools and knowledge, it can be done quickly and easily. The most important thing to remember is to take your time and be careful when working with electrical equipment. By following these steps, you will be able to identify the positive and negative speaker wire in your car and enjoy great sound quality from your speakers.
