What are the best options for upgrading the audio system in my Volkswagen Passat?

I recently bought a new Volkswagen Passat and the stock audio system is just not cutting it. What are some good options for upgrading the audio system without breaking the bank?

You can start by replacing the factory speakers with higher quality ones. Brands like JBL and Infinity offer great options at affordable prices.

Another option is to install a small subwoofer in the trunk. This will give you better bass response and enhance the overall sound quality.

If you want a more significant upgrade, you can replace the entire head unit with a new touchscreen unit. This will not only improve the sound quality, but also give you access to features like Bluetooth and Apple CarPlay.

Don't forget to soundproof your car doors for better acoustics. And make sure to properly tune your new audio system for optimal sound quality.
