How can I improve the sound system in my Toyota Yaris?

I just purchased a Toyota Yaris and while I love everything about it, I am a bit disappointed with the sound system. It lacks bass and seems to distort at higher volumes. Is there any way I can improve the sound in my car without breaking the bank?

I've had good luck with installing a subwoofer and amplifier in my Yaris. It definitely helped improve the bass and overall sound quality. You can also consider upgrading your speakers.

Adding sound deadening material to the doors and trunk can also help improve the overall sound quality. It's a bit more work, but can make a big difference.

If you're not looking to spend too much, try adjusting the settings on your sound system. Sometimes a simple tweak can make a big difference.
