BMW 8 Series G15 Coupe Speakers Upgrade Kit – Plug & Play Direct Fit Premium Door & Rear Audio Horn System, High-Fidelity Car Stereo Speaker Replacement for BMW 840i M850i M8 (2018-2026)

Upgrading your BMW’s audio is now as easy as assembling basic furniture.
The PUZU Ultimate Series is engineered for a flawless, non-destructive installation. No complex wiring. No custom fabrication. Just unbolt the old, drop in the new, and plug straight into your factory harness.you’ll have everything you need to complete the upgrade with absolute confidence.

Simply put, by utilizing premium materials and superior engineering, we deliver a more accurate and—most importantly—a far more enjoyable listening experience for you and your passengers.

Here’s why:

Every speaker relies on multiple physical characteristics that dictate its ability to faithfully and accurately reproduce recorded music: magnet design and materials, voice coil architecture, suspension, surround materials, cone composition, and more.

To keep production costs down, automakers frequently compromise in these critical areas.

The result is a poorly engineered speaker built with inferior components—such as cheap paper cones and harsh plastic tweeters. They might hit the car manufacturer’s budget target… but they sound terrible.

Sonically, this leads to high distortion, uneven frequency response, and sluggish transients. In other words, your favorite music ends up sounding dull, muddy, harsh, and fatiguing.

We absolutely refuse to compromise on product design or material quality. Because we don’t cut corners, you are able to experience breathtaking sound quality without needing to upgrade any other components in your vehicle’s audio system.

Furthermore, every speaker is meticulously engineered to integrate perfectly into your specific BMW model, down to the finest detail. We don’t build speakers to hit a specific price point; we engineer them to perfectly match your vehicle and its unique acoustics for the absolute best sound possible.

No other company goes to these lengths.

Yes. We designed the PUZU BMW speakers to perform in BMWs with a range of stereo systems, including the most basic options without a separate amplifier. The Ultimate series will still be a noticeable improvement over the factory speakers. To make the most of your new speakers, however, you may want to add our DSP amplifier series to boost your audio system.

Adding PUZU Ultimate series BMW tweeter PZ-TS25 to a vehicle that did not come with tweeters from the factory will require replacing a trim piece in the front doors, in which the tweeters will be mounted.

Thank you for your interest in our puzu products. Unfortunately we do not have any upgrades compatible with the Bang & Olufsen or Bowers & Wilkins audio systems.

For the B&O and B&W systems, our PUZU Ultimate series subs will fit in the under seat compartment however, the amp signal will cause our subwoofers to blow after mild use. For this reason we cannot offer them as compatible to your B&O or B&W audio system.

Our kits are designed and tuned specifically for the vehicle intended. We only recommend using the kit for your exact vehicle listed in our website’s vehicle selection options. So, if it is not listed we highly discourage trying to make another kit work.
