Sometimes the only desirable aspect of a long drive is the music that accompanies it. Whether it is your favourite CD or digital track or the local radio station, your music makes the drive a little more bearable. The Mazda 3 GT comes with an available Bose sound system option, which over time may prove to be insufficient for your musical needs. When this occurs, it is time for a musical hardware upgrade.

  1. 1

    Check your owner's manual for the specifications of your current Bose speakers and amplifier. These are the areas you want to upgrade, as a CD changer is going to play the same music, regardless of how new it is, but the speakers and amp are where your music receives its powerful punch.

  2. 2

    Obtain a new Bose amplifier. Amps are able to produce several thousand watts' worth of audio power, so it is important to see what your current Mazda amp is and locate an amp that is able to produce a more powerful sound. Once you know how powerful your Bose amp is, select replacement speakers that are able to handle this power. The watt power available for the speakers is printed on the packaging of the speaker equipment.

  3. 3

    Power down your Mazda 3 GT and access the current Bose amp. Depending on the model and year produced, the amp is either directly under the driver's seat or in the boot. Disconnect the current amp and insert the new Bose amp, then plug the equipment and wires back into the amp.

  4. 4

    Access your Mazda speakers. The exact method is going to vary depending on your model, so check the owner's manual for opening up the door panels where the speakers are held. Typically there are a few screws alongside the panel, which once removed allows you to pry off the panel and access the speaker.

  5. 5

    Disconnect the wires running into the speaker and remove the speaker. Insert the replacement speaker and connect the wires. Reattach the door panels and turn on your car to begin enjoying your new stereo system.
