How to Install Car Speakers

BY: CableOrganizer

Putting in new speakers is a great way to enhance the quality of your car's stereo system! Here's any easy-to-follow guide to help you through the key steps of your car speaker installation.


Experience Level: Intermediate

Time Required: 2 hours

Steps: 10

Supplies: Car speakers; resonance/vibration reducing material such as Dynamat®; door panel popper; heat gun; spray adhesive; roller; wire stripper; crimper; screwdriver; screws; wire loom or heat shrink tubing; small wire loom tool (optional); electrical tape.

Budget Estimate: Speakers can range from $20 to $200+; all other tools and supplies can run up to $150


Before you begin your project, remember to read the instructions for your specific car speakers.


To install new door speakers, use a popping tool to carefully remove the front door panel; after this is done, disconnect the old speaker and lift it out of the door.


Prep the Dynamat® for installation by warming it up with a heat gun. Apply spray adhesive to the section of the door you'll be installing the matting onto, then peel off the Dynamat's® backing.


Using the heat gun again, steadily direct hot air at the Dynamat® as you install it to the door's surface. Immediately after the Dynamat® has been applied, go over it thoroughly with a roller to ensure a tight bond.


Position the new speaker in the door cavity, and then secure it with screws.


Attach the wires that connect the car radio/CD player to the speakers. Insert the “positive” wires into the corresponding “positive” ports in both the radio and speakers, and plug the “negative” wire into the “negative” ports.


To install rear speakers, take off the grilles and remove the old speakers; replace with the new ones.


Wire the rear speakers in exactly the same way as the door speakers, plugging positive speaker wires into positive ports, and negative wires into negative ports.


Replace door panels in the front, and grilles in the rear.


To Cover Exposed Speaker Wires … We highly recommend that you cover any exposed wire in your stereo system with wire loom, braided sleeving, or heat shrink tubing. Not only will your speaker wires be protected from chemicals, automotive fluids and abrasion, they'll also look great! The product you select dictates how and at what point in the speaker installation process you'll need to apply the wire covering.

  • Braided Sleeving needs to be worked over the wires before they're connected.
  • Heat Shrink Tubing needs to be applied and shrunk before final wire connection.
  • Wire Loom is easiest to install before wiring is completed, but it's possible to carefully “zip” wires into loom after connection, using a small wire loom tool.
