How can I upgrade the audio system in my Toyota RAV4?

I am looking to improve the sound quality in my Toyota RAV4. What are some good aftermarket options for upgrading the audio system? Is it a difficult process to install these upgrades?

One option for upgrading the audio system in your Toyota RAV4 is to install new speakers. Consider high-quality speakers from brands like JBL or Bose. These can greatly improve the sound quality in your car.

Another option is to install a new head unit. This will allow you to connect your phone via Bluetooth or USB and have access to music streaming apps. It may also improve the overall sound quality.

If you want to go all out, you can also install a subwoofer to enhance the bass in your car. However, this may require professional installation and can be more expensive than just upgrading speakers or a head unit.
