Tips for Wiring the Speakers of Your Car's Audio System

All cars come with their own original manufacturer audio system. Some car owners, however, who put great value on their car's stereo equipment might find this pre-built system unsatisfactory for their audio needs. Some components that often get replaced are the speakers. Knowing how their wiring works can help a regular car owner do the replacement himself.

  1. Buy sufficient amounts of the correct speaker wires. Connecting speakers in a car will require considerable lengths of wires. Buy at least a spool of the correct speaker wires so that you have enough to work with and won't need to cut the project halfway through just to buy some more materials.
  2. Remove the car door panels. It might be a good idea to uninstall the car door panels so that you'll have enough room to work around. If the speakers are placed underneath the dash, then it will have to be removed as well. Make sure that you follow the step-by-step instructions for doing so from your car user's manual to avoid damaging any of the details of your car.
  3. Remove the current speaker wires. Most speaker wirings are hidden underneath the carpet so you'll have to pull it out first to do the job. Carefully cut the current speaker wires with the use of a wire cutter. Do it one at a time to avoid confusion - especially if the speaker wires you have are not the color-coded ones. Also, leave enough length of wire from the speakers and the radio. This is especially important if you'll be replacing the speaker wiring once more later on.
  4. Start installing the new speaker wires. Using a wire stripper tool, take out an inch of the rubber insulation from each end of the wires that are left on the speakers and stereo careful not to damage the copper wire strands within. Twist the open wire ends using lineman pliers. After that, secure the ends by attaching a wire nut. Seal the wire nut tightly using a crimping tool. Test if the connection you made is fixed firmly by giving it a little tug. If not, simply repeat the process to re-attach the wire nut properly. Also, remove an inch of the rubber insulation from the ends of the replacement wires. Now, all that's needed is to connect the speakers to the head stereo unit. Notice the slots intended for speaker wires at the back of the speaker. Grab the fresh wires and carefully attach the ends of the wire to the respective holes. Secure the connection you made by soldering the wire onto the speaker. Repeat the process to rewire the entire speaker system to the stereo console.
  5. Replace everything you uninstalled earlier. Put back the dashboard, seats or door panels you have removed earlier to finish off the job.

When working with wires and electrical systems, it's important that you observe all relevant safety measures to avoid hurting yourself or damaging the equipment you're handling. Connecting the wrong end of a wire to the wrong terminal at best leads to the equipment not working, but for stereo speakers for example it can also result in distortion and damaged speakers.
