Before you begin,How To Change a Car Stereo Articles start by setting the parking brake and removing the negative cable from the car battery to prevent accidentally short circuiting something.

Remove the factory stereo from the dashboard. You may need to remove some surrounding trim to access it. Disconnect the wiring harness from the back of the headunit. Simply press down the tab to remove it. Disconnect the antenna. Make sure you are pulling on the connector and not the wire as this may damage it.

Install door speakers. Pry the door panel away from the door. Be careful not break any of the electrical connectors, especially the side airbag connector. Unbolt and remove the door speaker. Remove the wiring for the old speaker. Then, install your new speaker to the door. Route your new speaker wires towards the factory amp in the front luggage compartment.

Install dash speakers. Pry off the speaker grills on the dashboard. Remove the speakers by prying out the retaining clips. Disconnect and remove the wiring. Install your new speakers. For the two side speakers it's recommended you install tweeters to produce high frequency noises.

Install subwoofers. Small subwoofer speakers can be installed to the door panel, but larger subwoofers come in an enclosure. It's common to put large subwoofers under the seats or in the back of the car. Once you have them installed, route the wiring to the front of the car.

Install the crossover in the front luggage compartment. Connect your speakers, tweeters, and subwoofers to the crossover in the appropriate filters.

Mount the car audio amplifier. Unplug and remove the factory amplifier. Secure your new amplifier so it will not move. Connect the power cables, cables for the crossover, and cables for the head unit.

Install the new head unit. Connect the connectors for the head unit and slide it into the head unit housing. Install the appropriately fitting dash kit. Return the side panels. When everything is connected, test the setup and tweak the head unit, amplifier, and crossover until the system works to your liking.
