How to Install Car Speakers – Step by Step Guide

Is it time to install new speakers? If you hear excessive rattling or humming or buzzing coming from your car speakers, it may be time to replace your old speakers. Or, if you’re looking for extra volume, you may want to add additional speakers. To install speakers in your car stereo system, you will need to connect the wiring to your existing speakers. It’s a simple process that you can do by following the steps below.

This post explains how to install car speakers. You will learn how to choose the right kind of speakers for your vehicle, how to measure the speaker for your car, and how to mount the speakers for maximum sound quality.

What Is a Car Speaker?

A car speaker is a device that converts an electric signal into sound waves. They are found in most vehicles and are used to provide sound for the occupants. There are many different types of car speakers, but the most common are the woofer, tweeter, and mid-range speaker.

Each type has a specific purpose and is designed to reproduce a certain range of frequencies. Car speakers can be damaged by exposure to water or excessive heat, so it is important to keep them properly protected.

  • The tweeter and mid-range speakers are designed to reproduce high frequencies;
  • The woofer is designed to reproduce low frequencies.

The two main types of car speakers are sealed and vented.

  • Sealed car speakers are designed to retain their shape and are not intended to be submerged in water.
  • Vented car speakers can be used in all weather conditions.

There are three main types of vented car speakers: coaxial, component, and coaxial tweeters.

Conventional car speakers are designed to work with specific amplifiers and have a number of crossovers and/or equalization circuits that help to match the frequencies of the tweeters, mid-range and woofer.

Car speakers are often mounted to the dashboard or in the door panel and controlled by a single subwoofer. The most common form of mounting is to screw the speaker directly into the dashboard, with an attachment for connecting to an amplifier. This is known as a “full range” speaker.

The term “full range” is misleading because the speaker is only able to reproduce sound at frequencies below a crossover frequency. Because of this limitation, most car speakers are active, meaning that they require a small amplifier in order to create the bass and midrange sound.

With the increasing popularity of car stereos, car radios and CD players, the size and power of car speakers has become more important. In addition to playing back music, many cars are equipped with a very small or even a built-in subwoofer.

In a stereo, the left and right channels are connected with an amplifier and speakers. The front channel is wired to the radio, CD player or MP3 player (if present), while the rear channel is wired to a subwoofer. 

What To Consider When Installing Car Speakers?

Car speakers are one of the most important features in a car. They not only provide sound, but also enhance the driving experience. When installing new car speakers, there are several factors to consider, including the size of the speaker, the type of speaker, and the location of the speaker.

The size of the speaker is important because it affects the sound quality. Larger speakers will generally produce better sound quality than smaller speakers. However, larger speakers can be more difficult to install and may take up more space in the car.

The type of speaker is also important. There are three main types of car speakers: cone, dome, and piezo. Cone speakers are generally considered to be the best type of car speaker because they produce good sound quality and are relatively easy to install. However, cone speakers can be very expensive.

The location of the speaker is important because it affects the sound quality. The ideal location for a car speaker is in the middle of the dash board, directly behind the driver’s head.

How To Install A Car Speaker

Step 1. Determine which speakers your stereo supports

Speakers consume power, and some stereos can’t handle a lot of extra power. Consult your stereo’s documentation when installing new speakers, especially if you are adding additional speakers or replacing existing speakers with higher-powered speakers.

Step 2. Make sure the speakers fit

Some speakers are designed to fit into existing speaker locations, while others will require modifications such as cutting the panel or installing mounting brackets. Keep all of this in mind when choosing speakers to install.

Step 3. Gather your tools

The tools you need vary greatly from car to car. The location of the speaker you’re installing will also have an impact on the tools you need. In general, however, you will probably need the following:

  • A variety of screwdrivers. Phillips, flathead, offset, and more.
  • Torx screwdriver
  • Drill and drill bits
  • Allen wrenches
  • Wire cutter/ wire stripper
  • Soldering iron
  • Crimping tool
  • Panel removal tool
  • Electrical tape

Step 4. Disconnect the battery

Before working on anything electrical in your car, it is always recommended to disconnect the power. Locate your battery and find the appropriate socket wrench that fits into the battery terminal lug. Disconnect the negative (black) terminal and gently move the cable to the side.

Step 5. Read the included instructions

There are too many different possibilities to be covered effectively in this guide. For specific instructions for your loudspeakers, refer to the included documentation or look for the manual on the manufacturer’s website. Always follow the manufacturer’s instructions.

Step 6. Remove the speaker grille.

These can usually be removed, although there may be screws that need to be removed. If you do this on the front of the dashboard under the windshield, you may need an offset screwdriver.

Step 7. Remove the old speakers

The speakers are usually screwed into the panel, so remove all the screws before attempting to remove the speaker. Be careful not to rip out the wiring harness that is usually present. The speaker may be stuck to the housing, so you may have to pry it off.

Unhook the speaker from the wiring harness after removing it from the panel. You will connect the new speaker to this harness. If there is no harness, you will have to cut the wires.

Step 8. Cut holes (if necessary)

Sometimes the speaker you are inserting does not fit exactly into the existing enclosure. If this is the case, use your drill to cut enough room for the speaker. Be sure to measure the new speaker and mark the enclosure so you don’t cut too much.

Step 9. Wire the new speaker

Most speakers simply clip into the existing wiring. If you don’t have a wiring harness, you will need to solder the new speaker to the existing speaker wire. Make sure the positive and negative wires are properly connected. The positive terminal on the back of the speaker is usually larger than the negative.

Avoid using tape to hold the bare wire together, as it is likely to warp and cause a bad connection in the future.

Step 10. Test them

Before mounting the speaker, reconnect the car battery and then test the speaker. Make sure that the sound coming out is not distorted and that the speaker is visibly moving at a higher volume. Before finishing the mounting process, make sure it is wired properly.

Step 11. Mount the speaker

After confirming that the speaker is working properly, mount it with the included mounting brackets and screws. Make sure the speaker is securely fastened so that it does not move and create excessive noise.

Tips for Installing a Car Speaker

  • Each speaker will have two wires, one positive and one negative, one wire will probably have a stripe on it, you can use this wire either positive or negative, remember whatever you use it for, make sure you are consistent on the other speakers.
  • Avoid running speaker wires where screws or panels may cut them.
  • Short screws may not fit the speakers securely. Use long screws to secure speakers to doors.


Installing car speakers is a relatively easy process that can be completed in a few hours. By following the steps outlined in this article, you should be able to get your new speakers up and running in no time. Remember to always consult your car’s owner’s manual for specific instructions on how to install new car speakers. And finally, always test your new speakers before taking them on the road.
