【Genuine Speaker Cable Specifications｜Includes Vehicle-Model-Specific Harnesses, Audio Installation-Friendly for Vehicles Wired Using Only Conversion Couplers】

In today’s vehicles, the wiring structure in areas that you can’t see has changed quite a bit compared with the past.
Especially in many vehicles, including Toyota models, the use of aluminum wiring for weight reduction and efficiency has become more common—so handling the factory wiring requires even more care than before.

If aluminum wiring is stripped and connected in the same way you would with copper wire, or if you casually “interrupt” it, it may lead to poor contact, oxidation, or corrosion.
The tricky part is that symptoms aren’t always immediate; after some time, you might find it becomes harder to get sound, or the system may become electrically unstable.

That’s why LOGON offers genuine speaker cable specifications that connect using only conversion couplers, without unnecessarily modifying the factory speaker wiring.
This specification also includes the vehicle-model-specific harness needed for installation, making it easier to proceed with speaker replacement and audio installation while minimizing damage to the vehicle’s original wiring.

Improving sound quality is, of course, important.
Just as important is avoiding as much as possible anything that could compromise the vehicle’s safety and reliability.

In recent vehicles, the speakers may do more than simply play music—for example, they may be involved with guidance audio or emergency audio announcements.
The configuration varies by vehicle model and factory system, but we believe choosing an installation method that is less likely to place extra burden on the factory wiring is an important point for enjoying the car with peace of mind for the long term.

The genuine speaker cable specifications are not visually flashy parts.
However, because these are areas that will become hidden later, making sure they are done properly makes a real difference in the sense of security after the installation.

At LOGON, we don’t build the setup by prioritizing sound quality alone and forcing the vehicle side to take unnecessary strain. We consider compatibility with the factory system, error risk, and future serviceability.
If it were me, on recent vehicles, I would be especially careful with these kinds of unseen areas.

“I want to improve the sound, but I don’t want to damage the factory wiring.”
“I want to replace speakers and install audio in a way that places as little burden on the vehicle as possible.”
“I also want to take into account the possibility of restoring the vehicle to factory condition later.”

If that’s what you’re looking for, this is a specification we’d strongly recommend.

To enjoy your important car for a long time, let’s think together about a good outcome—not only the final sound quality, but also how the wiring is handled.
