FAQ
Q: Can I install an aftermarket stereo in my BMW X5?

Q: Can I upgrade my X5’s sound system without replacing the factory radio?
A: Yes, you can. You can install new speakers, amplifiers, and subwoofers without replacing the factory radio. However, the factory radio may not provide enough power to drive the new components, so you may need to install an aftermarket amplifier to get the best sound.
