How To Change Car Speakers: Automotive Basics 101

Cars come with 6, 9, 12 (or more) speakers, depending on the variant/level. For some car enthusiasts and people who are into audio systems, they usually upgrade and have it be done by a third party or a service provider, or yet, they do it themselves. However, a new car owner with less knowledge about this but desires on learning how to change/upgrade speakers themselves may need a guide explaining the step-by-step process of changing car speakers. Don’t fret! Help is on the way.

Below are the DIY simple steps if you wish to learn on how to change your car speakers including some recommendations and the list of tools that you will need for this. Be careful to read all the instructions so that you will not miss important details.

Keep reading, and after which, test the newly-installed speakers and prepare your ears for some indoor concerts right in your car.

Decide if you want a car audio system with or without an external amplifier

Upgrading car speakers without an amp

Every car has already a built in amplifier in its audio head unit, but if you wanted to change your car speakers, you might need to check if this built in amplifier matches with your new car speakers. The amplifier must provide enough power for your new speakers because if it cannot, this can damage your speakers in the long run. Therefore, adding up an external amplifier depends on the power requirement of your newly-bought speakers. If the built-in amplifier can suffice, then it’s a cost saving for you.

Prepare what needs to be prepared

After you have decided about Step 1, prepare everything you need for this upgrade. Refer below for your guidance:

  • Prepare the newly-bought speakers
  • Prepare the tools and materials that you will need. The necessary tools are the following:
  • Door panel / door trim popping tool
    • Wire stripper
    • Crimper
    • Screws
    • Screwdriver
    • Heat shrink tube
    • Electrical tape
    • Heat gun
    • Spray adhesive
  • Dynamat – This is a noise stopper, in a nutshell. Because noise causes vibration and resonance, this is an important material for acoustics. (This is basically a mold sheet that’s thin and flexible)

Steps: Car speaker installation

  1. Carefully read the instructions indicated in the package of your newly-bought car speakers. This is a vital step on how to change car speakers.
  2. Every door has a door trim or door panel and if you are planning to replace all of your car door speakers, these door trims should be removed to access the built-in car door speakers. Use the door panel/door trim popping tool to remove these.
  3. Disconnect the speaker connectors with wires from the old speakers and remove the latter from their locations
  4. Place the Dynamat in the door surface but heat it up first by using the heat gun. Carefully spread the spray adhesive to the door surface and remove the back portion of the Dynamat.
  5. After step D, put the Dynamat and heat it up, and make sure the bond is tight.
  6. Get the new car speaker and place it in the location of the old speaker and then use the screws & screwdriver to fasten it.
  7. Connect the speaker connector with wires to the new speaker.
  8. You may try the newly-installed speakers by turning on your audio head unit and play a song before putting back the door trim/door panel.
  9. After trying out the new speakers, you may put back the door trims/door panels. Make sure everything is intact.
  10. If there are cases of wires being exposed, cover them with heat shrink tubes. Take note that these tubes should be shrunk before connecting the wires.
  11. These steps apply to the rear car speakers as well. You may follow these steps on how to install rear car speakers.

Car speaker installation cost

Actually, the cost starts with your newly-bought speakers. You may choose a brand that’s expensive, or you may choose something that just fits your budget. Aside from the brand, it also depends on the power of these speakers, which relates to what I have mentioned in step 1. If the speakers’ power requirement cannot be sufficed by the built-in amplifier, then you need to buy an external amplifier that matches.

With regards to the tools and materials needed, if you still don’t have any of these, then it would cost you around $100 at a minimum, but if you already have some of these, then it would not cost you that much.
