Since most genuine products these days have aluminum wiring, you can easily and reliably install them using a conversion coupler!

【Genuine Speaker Cable + Additional Cable Specifications | LOGON Original Wiring Specifications That Reduce Load on OEM Wiring by Including Vehicle-Specific Harnesses】

In recent vehicles, the way audio-related wiring is designed has been changing from the past.
Especially with Toyota vehicles and others, as the trend toward lightweighting and improving efficiency continues, cases in which aluminum wiring is used in the factory wiring have been increasing.

What you need to be careful about here is modifying the genuine (OEM) speaker wiring.
If aluminum wiring is stripped or interrupted in an easy manner with the same mindset as copper wire, it may lead to poor contact, oxidation, or corrosion. Moreover, symptoms may not appear right away—there is also the possibility that, after some time, the sound becomes harder to produce or the system becomes electrically unstable.

That’s why LOGON offers a “Genuine Speaker Cable + Additional Cable Specifications” that connects using a vehicle-specific harness and a conversion coupler, without needlessly modifying the OEM speaker wiring.

Add the Necessary Cables Properly Without Damaging the OEM Wiring as Much as Possible

This specification is LOGON’s original installation method that keeps using the OEM speaker cables while combining additional cables—for example, for tweeters or rear speakers— as needed.

Because the vehicle-specific harness is included, it is less likely to directly burden the OEM wiring, and connections during a speaker replacement or audio installation can be organized neatly.

In a speaker replacement, improving sound quality is, of course, important.
However, in today’s vehicles, we believe it is just as important not to compromise the vehicle’s safety and reliability.

Speakers are not only used to play music—they may also be involved in vehicle guidance voice output, warning sounds, and system sounds. The configuration differs depending on the vehicle model and the OEM system, so it is crucial not to take the wiring lightly and to choose a method that is less likely to cause trouble later.

It’s Invisible Work—So This Is Where You Should Do It Properly

The Genuine Speaker Cable + Additional Cable Specifications are not parts that change dramatically in appearance.
But because this is the kind of portion that gets hidden inside the interior after installation, taking care to make things like this properly can make a difference in the peace of mind you feel while driving for years.

If it were me, I would handle these kinds of invisible wiring areas even more carefully than with older vehicles.
Rather than prioritizing sound quality alone and forcing the vehicle side, we consider the configuration while also taking into account compatibility with the OEM system, error risk, and future serviceability.
