how to install car speaker



Installing car speakers is a snap. It only takes a few tools and some electrical knowledge to replace factory-installed speakers with aftermarket units. Here's how to do it:

Prepare the wiring harness.

  • Use a wiring harness that is designed for your car. If you’re buying a new speaker, make sure the wiring harness is compatible with the speaker you want to install and your vehicle. If you already have the speakers in place and are simply adding another set, make sure it’s compatible with all of your amplifiers and other devices.

  • Check to make sure the wiring harness has all of the correct connectors for your vehicle's electrical system (or lack thereof). You may need a custom adapter if there aren't any available on eBay, but it's worth looking into before buying any parts or tools so that this isn't an issue later on down the road!

Make the correct connection to your new speaker.

Make sure the speaker is compatible with your car.

  • The type of car stereo you have, and whether it allows for upgrades like a new speaker system, will affect which speakers you can use. If you have an older or low-end model of stereo, it may not be able to support an upgraded system. You should also check with the manufacturer of any aftermarket parts that you plan on using to make sure they match up correctly.

  • If a part does not match up correctly with your vehicle’s original equipment or another component in it (like a radio), there may be issues with sound quality, power output or even damage to other components in the long run.

Connect your audio input cables to your output cables.

Now that you have your new speakers installed, it's time to connect them! First of all, make sure that the cables you're using are the right ones for your car. If they aren't, they won't fit into any of the ports and terminals on your head unit or amplifier.

If you're unsure about whether or not a cable will fit into a port or terminal, check out our guide on how to choose an audio input cable ( Once you've selected an appropriate cable, remember two things: firstly, double check which ports are connected where; secondly, ensure that polarity is correct before plugging in any cables.

You'll also want to make sure that all connections are secure if there's any kind of tension on an audio input cable as soon as it's plugged in (such as when someone puts his suitcase down on top of an amplifier), this could cause damage to either component involved in transmission between them!

Unplug the car battery before making any electrical connections.

This is a good idea for safety reasons. If you’re going to be working with the electrical system of your car, it’s a lot better if the battery is disconnected from everything else. If you accidentally short-circuit something, there won’t be any current flowing through your body (which could cause serious injury or even death) thanks to this precautionary measure.

If you don't have time before beginning to install speakers, then disconnecting the battery should be one of your first priorities after getting started on the job. You can always reconnect it later once all the wiring work has been done and everything is tested for proper operation!

Use a multi-meter to test your wiring harness.

The wiring harness is one of the most common sources of problems in car audio installations. The wires can become frayed or damaged by a variety of factors, including general wear and tear and poor installation practices. A good way to test the wiring harness is with a multi-meter, which will allow you to verify that there are no shorts or bad connections in your system.

To use a multi-meter:

  • Insert one end of the black clamp into "COM" on your multi-meter and insert the other end into ground (usually indicated as “GND”). The COM connector has two holes where you can insert either wire from your red lead or black lead depending on what is being tested. Connecting it here ensures that if anything goes wrong during this process that nothing will happen because both wires are safely connected together via the COM port when using this method for testing purposes only!

  • Set your meter to test continuity (this is usually labeled “CONT”). If there is continuity between two points within an electrical circuit then it means they share an uninterrupted pathway through which current can flow so connect them together with another wire if possible otherwise just make sure they touch each other as closely as possible without causing any short circuits within either device being tested before proceeding onward."

Use the right tools for the job.

When installing your car speakers, you want to make sure that you're using the right tools for the job. The right tools will help you get better results when installing your new speakers, which can save time and increase safety.

To test your wiring harness: A multi-meter is a handheld device that can be used to test circuits. This tool will allow you to check if there are any problems with your wiring harness before installing new speakers into it.

To remove old speakers: You'll need some basic hand tools like screwdrivers and pliers to remove old car speaker units from their mounting brackets in order for them to be replaced by new ones later on in this process; these items are available at hardware stores or other retailers depending on where you live/work/drive around in vehicles often enough for this project's purposes (i!e., maybe not necessary if living somewhere rural).

With the right tools and some patience, you can install car speakers on your own.

If you're not a car audio professional and are interested in installing car speakers, the first step is to make sure you have the right tools. You'll need a voltmeter to test your wiring harness before connecting it to the new speakers. You'll also need some crimp connectors, wire strippers and electrical tape.

Once you've gathered all of these materials together and made sure they're within reach of where you'll be working on your car's speaker installation project, it's time to start making connections. Connecting an aftermarket speaker involves attaching an input cable from one end of the wiring harness and then connecting this end with another set of cables from either side or both sides of your stereo system (depending on whether there are only two or three jacks).

The next step involves testing those connections by plugging in everything at once: a power source for each one; turn on any auxiliary components like amplifiers; then turn up the volume so that it gets loud enough but doesn't distort sound quality too much. If everything works properly without any problems, take note which wires lead where so if something goes wrong later down the road after installation has been completed successfully (and all systems checked out), repair efforts will be less costly than they would've been had mistakes been made earlier!


With the right tools and some patience, you can install car speakers on your own. It’s important to do your research before starting any project so that you know what you’re getting into and how long it will take. If you don’t feel comfortable doing the job yourself, then find someone who does!
