対応可能です even for vehicles with the factory premium sound system.

However, the available options vary depending on the vehicle model, model year, and the configuration of the factory system, so we guide you while confirming the best approach based on your situation.

Factory premium sound vehicles often come with dedicated amplifier and speaker configurations from the start, so the installation methods and the points that are easier to improve can differ a bit from standard audio-equipped vehicles.
Therefore, before deciding on a product, it’s important to check how your current factory system is set up and assemble a plan that stays within reasonable limits.

At LOGON, we make proposals while organizing the direction you want to take according to the system configuration for each vehicle and the changes you’d like, such as:

• Want to make the sound a little easier to listen to
• Want to compensate for the lack of bass or vocals
• Want to keep the factory usability as much as possible

It’s not necessarily the case that factory premium sound is uniformly difficult; however, depending on the specifications, you may need to confirm the equipment to use and the details of the work.
If you’re unsure, you can consult us to the extent you know the vehicle model, model year, and current audio specifications, and we can organize the most straightforward way to proceed together.
