【Center Relocation Work for the Alphard Guidance Speaker】

In its original configuration, the Alphard is set up so that the navigation voice, vehicle announcements, and various guidance sounds come from the left-side speakers.

When you listen from the driver’s seat, the sound may seem shifted to the left, and even if you increase the volume, the ease of hearing doesn’t improve much. In such cases, you may want to consider the center relocation work for the guidance speaker.

Easier to hear from both the driver’s and passenger’s seats

By relocating the guidance sounds that were previously shifted to the left to the center side, the system can be tuned so that they are naturally easier to hear not only from the driver’s seat, but also from the passenger’s seat.

Since this affects not only the navigation guidance voice, but also announcements from the vehicle and various guidance prompts, it’s work that influences not just audio sound quality, but also day-to-day usability.

Especially when replacing speakers or converting to 3-way (3WAY), it’s important to consider how the factory guidance sounds will be handled as well.

Installation that does not compromise safety-related audio

This speaker is involved not only in navigation audio, but also in important vehicle sounds such as emergency calls.

Therefore, we cannot recommend installation that simply changes wiring in a way that causes the audio to stop playing. If the audio is unable to play, it could affect important vehicle functions and potentially even impact vehicle inspection (shaken) compliance.

At LOGON, we do not sacrifice the vehicle’s original functions for the sake of audio. While preserving the factory’s important functions, we confirm the best way to make guidance sounds easier to hear, tailored to the vehicle specifications and the planned installation details.

Work that may be necessary for 3-Way conversion

When swapping speaker wiring for a 3-way conversion (3WAY) or similar changes, it may be necessary to perform this guidance speaker relocation work.

On the other hand, if you replace speakers while using the original factory cables as-is, the relocation work may not be necessary in some cases.

Even with the same Alphard speaker replacement, the required work can vary depending on the speakers you choose, the wiring method, and the system configuration. Rather than deciding the installation details in advance, we propose only the necessary modifications while looking at the current factory system, the sound you want, and even future expansion.

If you’re concerned that “the guidance sounds feel shifted to the left,” or if you’re thinking about “3-way conversion but unsure how to handle the factory announcements,” please feel free to consult us.

We’ll work together to think through a finish that suits your Alphard—not only in terms of audio sound quality, but also considering the vehicle’s overall day-to-day usability.

Installation details

• Center relocation work for the guidance speaker
• Consideration for factory guidance sounds and vehicle announcements
• Confirming wiring methods in line with speaker replacement and 3-way conversion
• Considering an installation approach that preserves important vehicle audio functions
• Confirming that guidance sounds operate properly after installation

About installation labor charges

Because the work content changes depending on the mounting method and the existing audio configuration, we provide accurate labor charges after confirming your vehicle and the details of the planned installation.

If you’re considering Alphard speaker replacement and/or 3-way conversion as well, we will review the direction of the sound you want and your current system, then organize the necessary work and make proposals accordingly.
