Tesla Model 3 Highland (2023+) Audio upgrade.

Tesla Model 3 Highland (2023+) Audio upgrade.

This upgrade consists of installing a Mosconi amplifier and installing 2 pieces of 20 cm Hertz subwoofers that are then built into the parcel shelf.

This is in the same location as they are in the high-end Model 3 and therefore does not take up any space.

As an option, we can replace the bass speakers in the front doors with heavier 20 cm ones. This will also improve the sound.
