BMW Stage One Speaker Upgrade for E63/E64 Coupe/Convertible with Standard Hi-Fi - Bavsound BSD.S1.E63E64.HF-Kit

Product Information

A car speaker is an audio device installed inside a vehicle that converts electrical signals into sound, allowing you to hear music, navigation prompts, or phone calls. They come in various types—like woofers, tweeters, and mid-range speakers—to cover different sound frequencies for a full audio experience.

• Distorted or Crackling Sound: Buzzing, popping, or crackling noises often indicate damaged speaker cones or wiring issues.
• No Sound or Intermittent Sound: A completely dead speaker or one that cuts in and out could mean blown speakers, bad connections, or amplifier problems.
• Rattling or Buzzing at High Volume: Loose components or damaged cones may cause unwanted vibrations.

About Bavsound

Bavsound takes factory BMW/ MINI speakers and re-engineers them for one thing: clarity. Their plug-and-play speaker and subwoofer upgrade kits are an approachable way to bring your audio to the next level.

Our Stage One speaker upgrade produces higher quality sound, with a wider range and more balanced reproduction of the bass and treble you're currently missing. Unlike the factory speakers, we use proven audio technology: woven fiberglass cones, butyl rubber surrounds, and silk composite tweeters. This results in speakers that remain distortion free at higher volumes, and you get accurate, natural, beautiful sound at much higher volumes.

Our Ghost under seat subwoofers are the perfect upgrade to dramatically improve bass response in your BMW. They will give you a much tighter, louder, punchier bass, and drastically transform your music. They are engineered for efficiency, and maximize every watt of power generated by your amplifier to yield far more bass output than your factory subwoofer. You get breathtaking bass response.

On top of all this it is 100% plug and play with your factory system, and typically no modification to the vehicle is required.
