My G55 AMG Sound System Was Terrible - G-Wagon Speaker Install Polk Audio + 3D Printed Adapters

Описание: In this video, I completely upgrade the speakers in my Mercedes AMG G55 (W463 G-Wagon) by replacing all six main factory speakers — front doors, rear doors (component sets with tweeters), and the rear cargo area.

If you’re just looking to upgrade your speakers in a W463 G-Class, this is the step-by-step guide you need.

To keep everything OEM-looking, I 3D printed custom speaker adapters for both the front and rear doors. The new 6.5-inch speakers bolt directly to the adapters, and the adapters bolt directly into the factory mounting locations — no drilling, no door modifications, and no permanent changes.

For this build, I used Polk Audio DB Series speakers:
Rear doors: 6.5" component sets with separate tweeters (installed in factory locations)
Front doors: 6.5" two-way speakers with integrated tweeters
Rear cargo area: 5.25" two-way speakers

I walk through:
• Removing rear door panels
• Removing front door panels
• Accessing factory speaker locations
• Installing tweeters in OEM rear door positions
• Removing rear cargo trim
• Cutting clean openings for 5.25" cargo speakers
• Achieving a factory-style finish

The result is a massive improvement in sound quality while keeping the interior looking completely stock.

3D printed adapters DIY, download the STL file and print your own: https://www.thingiverse.com/thing:548...
3D printed adapters, I can mail you a set: email me at nkpracing at gmail
I use the Bambu X1C 3D printer. But for simple stuff like this if you don't 3d print often, I'd recommend a Bambu A1: https://amzn.to/4b2l03L

In the next video, I’ll be installing a new amplifier in the factory location using much of the original wiring.

More G-Wagon upgrades coming soon.
