[Re-Adjustment of an Aftermarket Deck｜An original Log On menu to make your current sound right, using the navigation/audio installed at other shops]

You replaced your factory navigation or audio with an aftermarket one, but the sound doesn’t turn out as good as you expected.
You may feel that the vocals are too far away, the bass is blurry, the treble is too sharp, or the left/right balance is off. In such cases, before replacing your equipment, it’s worth taking another look at your current system first.

Car audio isn’t something that’s finished just by installing a head unit (deck) or speakers. Even with the same equipment, what you hear will change depending on the speaker position and orientation in the cabin, the installation condition, how each speaker is connected, and the deck settings.

With Aftermarket Deck Re-Adjustment, even for navigation and audio decks installed at other shops, we will check the current system configuration and how it sounds inside the vehicle, and then figure out ways to make the most of the equipment you already have.

First, confirm what feels “off” about your current sound

Re-adjustment isn’t only about changing numeric values on the settings screen. While actually playing the music you normally listen to, we’ll整理 together what exactly you’re concerned about.

For example,

• You want the vocals a little closer and more natural
• You have plenty of bass, but it’s blurry and doesn’t feel cohesive
• The treble sticks out and becomes tiring when you turn up the volume
• You’re concerned about the location and spread of the sound between left and right
• The connection between the subwoofer and front speakers feels unnatural

We’ll check items such as the equalizer, time alignment, crossover, and each speaker level—tailoring the setup to the cabin conditions and your preferences. While making use of each piece of equipment’s strengths, we aim for a sound that you won’t get tired of even on commuting or long drives.

Even if it was installed by another shop, we start by judging based on the current condition

With systems installed at other shops, the range you can adjust varies depending on the installed deck and speakers, wiring, installation method, and door-side processing, among other factors.

Sometimes simply re-checking the settings can change how the sound feels. However, there are cases where the sound can’t be fully fixed with adjustments on the deck side alone—because of issues such as the speaker installation condition and polarity, wiring, door processing, or the way the subwoofer is integrated.

Don’t assume based only on email or equipment model names. After confirming the sound and the installation condition on the actual vehicle, we’ll separate which parts can be improved through adjustment and which parts should be reconsidered starting from the installation.

Rather than forcing you to replace speakers or the deck, we first confirm how far the current system can be tuned. If it were me, I’d consider it in this order first.

Use your current equipment to align the direction of your sound

The sound you’re trying to achieve differs from customer to customer—such as “I want more bass,” “I want the vocals brought forward,” or “I want a sound that doesn’t get harsh even when I raise the volume.”

So instead of matching numbers across the board, we’ll adjust while checking the vehicle model, speaker configuration, the music you usually listen to, and your current complaints.

In some cases, adjustment alone is enough to improve things significantly. In other cases, depending on installation conditions and combinations of equipment, you may need to rethink other aspects as well. We won’t be vague about what can be done and what’s difficult—if necessary, we’ll honestly explain even the next steps.

Recommended for people like these

• You swapped to an aftermarket navigation or aftermarket audio, but the sound just doesn’t feel right
• You want the sound after an installation by another shop to be checked once by a specialist shop
• You’re concerned about the vocal position or left/right balance
• The bass is too strong or feels thin
• The treble is harsh and you get tired after listening for a long time
• Before adding speakers or a DSP, you want to know what can be done with your current equipment
• You tried changing settings yourself, but you don’t know what to fix

Aftermarket Deck Re-Adjustment isn’t a menu for adding new equipment. It’s a menu to confirm the condition of the system you already have and to tune how it’s played.

Without worrying that it was installed by another shop, please tell us what you’re not satisfied with in your current sound. If your current deck can be leveraged, we’ll use it; if there are things that need to be rethought, we’ll decide the order. Matching your vehicle, we’ll tune the sound together in a practical, no-excess way.
