【Car Audio｜Rear Luggage Installation Multi-System 8CH or More (Including Labor Charges)】

I want to make the sound of the factory audio a little more natural.

I want to hear the vocals around the center of the dashboard. I don’t just want the bass to stand out— I want a cohesive sound throughout the entire cabin, from the front speakers to the subwoofer.

This is the rear-luggage-installed multi-system plan with 8CH or more (including labor charges) tailored to those goals.

We’ll consolidate equipment such as DSPs and amplifiers on the rear luggage side, creating an environment where each speaker can be finely adjusted—while keeping the look inside the cabin and the usability around the seats as intact as possible.

What You Can Do with a Multi-System of 8CH or More

With a multi-system, you can individually adjust components such as tweeters, midranges, mid woofers, and rear speakers according to their respective roles.

Because it becomes easier to fine-tune sound imaging and soundstage width, vocals can sound more naturally like they’re right in front of you, and the positioning relationships of instruments become clearer.

Bass isn’t just about increasing volume. By adjusting while checking how the front speakers and subwoofer connect, we aim to suppress the impression that only the bass is playing from the back, and to achieve a cohesive sound across the whole cabin.

Even with songs you’ve listened to for a long time, you may start to hear sounds you previously hadn’t noticed. Without having to turn the volume up too much, it becomes easier to enjoy the nuances and expressions of vocals and instruments.

That’s what makes a multi-system so interesting—you can target those kinds of changes.

However, simply having a higher number of channels doesn’t automatically result in good sound. It’s important to bring everything together properly—from speaker combinations, installation methods, wiring treatment, and how the equipment is packaged, all the way to the final sound tuning.

Front 2-Way + R vs Front 3-Way

Front 2-Way + R is suited for those who want to focus on tuning the front stage while also taking advantage of the rear speakers.

It’s a well-balanced configuration for people who often have passengers in the back seat or for those who want to improve the overall cohesion of the sound without drastically changing the factory usability.

Front 3-Way separates adjustment for the tweeter, midrange, and mid woofer, making it ideal for those who want to more precisely dial in front sound imaging and the sense of separation in the sound.

If you want to enjoy even small differences in vocal expression and instrument detail, there’s a great sense of satisfaction once it’s finished.

Which one to choose isn’t determined by the vehicle model or the specifications of the factory audio alone.

• How you usually listen to music
• How often you use the rear seats
• Whether you place luggage in the rear luggage area
• Whether you’re considering upgrading the system in the future
• Where you want to focus your budget

Depending on these conditions, the configuration that fits best will change.

If I were choosing, I wouldn’t decide only based on the number of channels or the configuration at the beginning. I’d confirm your actual vehicle and then choose a direction that’s less likely to lead to regrets.

Why We Consolidate Equipment in the Rear Luggage Area

When you install a DSP and amplifier in the rear luggage area, even equipment that’s difficult to fit neatly under the seats can be laid out more easily with relatively more space.

It also makes it easier to consider wiring treatment and maintainability, and it’s a good way to keep the overall system organized even if you plan to add a subwoofer or additional amplifiers later.

On the other hand, for people who frequently use the rear luggage area as a place to store items, loading capacity and how the equipment looks also become important.

You need to decide the installation details while considering not only appearance but also everyday usability: how the equipment will be fixed, whether to add covers, and how much it will affect the area when you load luggage.

At LOGON, we don’t just line up components. We install while keeping a balance of sound, usability, serviceability, and appearance in mind.

Wiring and fixing methods that are hard to see from the outside are also essential parts for using everything safely and comfortably for a long time.

The Meaning of Installing at LOGON

Even if you use the same equipment, the way the sound comes together will change depending on the car.

How do you extract the signal from the factory system? How much of the factory functions do you keep? Where do you play the speakers, and how do you adjust them?

These factors greatly affect the impression of the final result.

That’s why we recommend not deciding the system configuration and installation method just by email, but confirming your typical usage and sound preferences while seeing your actual vehicle.

Should we start with front 2-way + R so it’s easy and sensible, or finish it with front 3-way considering the future? Can we make use of the equipment you already have? Which parts would be better to replace?

We’ll go through these points together, including how to allocate your budget to the parts that will affect the sound.

For those who want to create truly great sound while using the rear luggage area and maintaining everyday cabin usability, this is a plan worth considering carefully.

Let’s build a car audio setup that you can enjoy comfortably for a long time—while confirming your vehicle specifications and how you usually listen.
