【Trade-In Under-Seat Woofer for BMW MW 8BMW-D｜20cm Subwoofer Set】

This is a set of two 20cm trade-in under-seat woofers, designed for those who want to add a bit more low-end thickness and natural punch to their BMW factory audio.

Built to fit easily in the factory woofer location under the seat, it lets you properly establish a solid low-end foundation without significantly changing the look or usability inside the cabin. Instead of making only the bass stand out, it supports the vocals and front speaker sound from below—helping the entire music feel fuller.

With the factory system, you may find that the bass feels weak when you turn the volume up, or that the music’s impact is missing that one step. The MW 8BMW-D supports the subwoofer range with a frequency response of 15Hz to 140Hz, making it a model that’s easy to integrate with the front speakers and split the roles effectively. By adjusting not only the amount of bass but also the connection with the front speakers, you can bring your everyday songs closer to a more calm and easy-to-listen sound.

Also compatible with DSP amplifier setups

It uses a 2Ω dual voice coil (DVC) specification, so it is compatible with the PP62DSP subwoofer output. You can also consider combinations with systems that provide 4ch subwoofer outputs, such as PP50DSP and PP1SUB.

However, even for the same BMW woofer, the appropriate connection method and adjustment details will differ depending on the vehicle’s factory audio specifications and your current system configuration. It’s important not to just swap it in, but to finish the setup while checking the balance with the front speakers and the DSP amplifier.

At LOGON, we organize this together: after confirming your vehicle model, factory system, and what you’re dissatisfied with in the current sound, we’ll help you figure out whether a woofer-only replacement makes sense or whether you should also consider DSP amplifiers and other components.

If you want to improve the lack of low-end without drastically rebuilding your BMW factory audio, please show us your current system first. If I were doing it, I would not decide the woofer first in isolation—I’d confirm the integration with the front speakers before planning the full configuration.
