BMW 3 Series Audio Upgrade - sound that fits your car

Make your BMW 3 Series sound the way it's supposed to sound

The BMW 3 Series is known for its balance of comfort and sportiness. But the sound system? That comes standard with many versions - and you can hear it. Moderate bass, little definition and shrill treble make long drives less impressive than they could be.

At Eye4Audio We offer a high-quality audio upgrade for the BMW 3 Series. Whether you drive an F30, G20 or E90, we provide tight sound with no visible modifications.

What we improve

Our systems are built with components from Audison, Hertz and AudioControl. Each component is carefully matched to your car and your preferences.

✅ Audison Prima component speakers front and rear

✅ AudioControl DSP amplifier with custom tuning

✅ Compact subwoofer (optional, fully concealed)

✅ Door and panel damping for peace of mind and efficiency

You keep your current infotainment system. No messy cables, no dashboard modifications.

OEM finishing without concessions

  • No damage to your car

  • No universal units

  • Everything is professionally concealed

  • Controls and functions remain as you are used to

Your 3 Series remains 100% BMW - with sound quality that finally matches it.

Frequently asked questions (FAQ)

Does my radio need to be replaced?

No. Our upgrades work with your existing factory radio. Still want a screen upgrade? You can, too.

Do I really hear a difference with just speakers?

Definitely. Especially in combination with damping, your music already sounds much fuller and quieter.

Can I also upgrade without a subwoofer?

Yes, a sub is optional. But if you really miss low, we definitely recommend it.

Is it also suitable for leased cars?

Yes. Everything is reversible and invisibly built in.
