Yes, it can be improved.

On expressways, tire noise and wind noise increase all at once, so even music that sounded just right during city driving tends to get buried.
Especially with factory audio, the sound is often tuned with everyday usability in mind, and there are many cases where it hasn’t been fully adjusted for how easy it is to hear at higher speeds.

At LOGON, we don’t just suggest turning the volume up—we propose improvements in a direction that makes voices and melodies naturally easier to hear while driving.

Common measures include the following.

• Speaker replacement
  Compared with the factory setup, the sound’s contours tend to become clearer, and vocals and instrument sounds are less likely to get buried.

• Work around the doors
  By creating conditions in which the speakers can play more firmly, the sound becomes less prone to getting blurry.
  At the same time, it may also be easier to soften the impact of noise coming in from outside.

• Adding an amplifier and adjusting the sound
  You can often get a better balance from small to loud levels, and even on expressways you may be able to listen more comfortably without forcing the volume too high.

• Car-specific setup
  Even with the same products, how it sounds changes depending on the vehicle model, installation method, and usage.
  At LOGON, we finish the setup while prioritizing how it will sound in your specific car.

In practice, what you choose depends on how much you want to improve.
Some people want to make it easier to hear the news or vocals on the commute, while others want to enjoy music properly even on expressways—so the needed measures aren’t the same.

That’s why, rather than assuming something major right away, it helps to think in terms of:

• First, improve primarily with speaker replacement
• As needed, combine installation work and adjustments
• Depending on your preferences, move on to a higher plan

With this approach, there are usually fewer chances of failure, and satisfaction tends to be higher.

For cost and details, you can check rough guidelines on LOGON’s Audio Plan page.
Because the selected content is clearly shown as a total cost estimate, it’s easy to compare even for first-timers.
If you’re still unsure after looking, we can guide you based on your budget and your goals, such as “wanting to hear more clearly on expressways.”

If you feel that you can’t hear well even when you raise the volume or that you get tired on long-distance drives, it’s often not just that the sound is too quiet—adjusting how it sounds itself usually makes things much easier.
Since we get many consultations like yours, you can start by considering your current dissatisfaction as the baseline.
