For more on speaker systems, check out our article that shows you how to set up speakers in the best position to increase your overall sound quality.

Insider Tip

While you don’t have to install all speakers at once, installing both dash speakers and rear speakers as matching sets is recommended.


Begin Removing any paneling and screws covering the car’s factory speaker.


Disconnect the speaker from the harness wire and unscrew the speaker from the bracket. Remove the bracket itself if you have an adapter bracket.


Take out each speaker wire from the positive and negative terminal.


Take the two wires and reconnect them to the positive and negative terminals. Remember, the positive terminal is larger, and the negative is smaller.


Place the wire harness into the new speaker. Then place electrical tape over the connected wires.


If you had to get an adapter bracket, screw in the installation equipment, and screw in the speaker.


Carefully put back all the screws and paneling you had to remove at the beginning of the project. Repeat this process until all the replacement speakers are installed.


When screwing in a new speaker, ensure that each screw is tight. If you don’t do this, it can cause an annoying rattling sound or eventually lead to speaker damage.


What is different about a factory car speaker?

Factory speakers often have lower sound quality for a few different reasons: lower power output, cheaper parts, and lower bass and mid-range are the main ones. On the other hand, custom speakers often provide extra power and a broader audio spectrum.

What should I be looking for when purchasing car speakers?

The first thing to understand is what size speakers your car holds. Understand the ideal power output needed for your stereo, and then look into the cost.

What can I do to make my car door speakers sound better?

Properly insulating any dead spots in the door panels and around your speakers is great for increasing sound quality. You also should check all screws to make sure they aren’t rattling when music is playing.

STAT: A mid-level replacement car sound system will cost you around $500. (source)
