CAR PLAN

DSP Amplifier Add-on Plan

“Even after replacing the speakers, it didn’t get as good as I expected.”
This is the plan we’d like you to look at first if that’s you.

This plan is the core of our sound-quality improvement approach—suitable for those who want to improve sound while keeping the factory audio, as well as for those who have already replaced their speakers.
It’s ideal if you want to properly tune the sound inside the cabin without making major changes to appearance or day-to-day usability.

Dissatisfaction with sound isn’t necessarily caused only by the speakers.
In practice, there are many cases where the timing at which sound reaches your left and right ears is slightly off, or where the connection between high, mid, and low frequencies doesn’t line up well—leading you to feel things like “it just isn’t easy to listen to,” “the vocals scatter,” or “the sound doesn’t come forward.”

That’s where a DSP amplifier makes a big difference.
A DSP amplifier isn’t a machine that simply makes everything louder—it finely adjusts how sound is produced to match the interior of your vehicle.
Align the left-right timing.
Balance the strength of the sound.
Naturally blend the connection across each frequency band.
With these adjustments, the vocal position becomes stable and the overall sound becomes easier to pull together.

So this plan isn’t just about adding equipment.
It’s about finishing things with the question: “How should the current system sound in this current cabin?”—included as part of the plan.

Even with factory speakers, you can expect results, but on vehicles where speakers have already been replaced, it’s also not uncommon to clearly see the performance that you previously couldn’t fully draw out.
Even if you install great speakers, if the way they’re driven isn’t right, their good qualities can get buried.
This plan’s role is to properly dial that in and bring the sound closer to completion.

For installation, we determine the configuration based on your current system setup, and proceed while also checking the balance with factory functions.
Another reassuring aspect of this plan is that we can build it in a way that minimizes changes to your usual day-to-day usability and doesn’t significantly disrupt the appearance.
“I want to keep the factory feel.”
“I don’t want it to look like an afterthought, if possible.”
This is a plan that’s easy to incorporate even for people like that.

Also, of course we support customers who had us install their speakers. We also respond to inquiries from customers who had speakers installed elsewhere or replaced them via DIY.
Depending on the vehicle and the current state of your equipment, some confirmation may be needed, but if you provide photos and information that shows the configuration in advance, we can judge whether installation is possible and how to proceed.
Even if you’re worried it might end up being a full redo from the start, we can guide you in a reasonable way after first checking your current condition.

From a real-world, on-site perspective, cars that have a DSP amplifier installed and properly tuned make a significant difference in how easy they are to listen to.
You’ll feel less like the sound is scattered, and the music naturally gathers toward the front.
You’ll fatigue less even after long listening sessions, and even at lower volumes, the finer details become easier to hear.
This is the biggest value of this plan—something that’s often hard to convey with just numerical specs.

If you want to further enhance not only clarity but also the thickness of the bass and the overall scale of the music, there’s a next step: adding a subwoofer.
That said, many cases still see a solid improvement in satisfaction even if you start by simply tuning the foundation with a DSP amplifier.
Another good point of this plan is that you can refine things step by step rather than going all-in immediately.

Keep your current car, and move your sound up one level.
Even if you’re in a “I don’t know what I should change” situation, you’re fine.
We’ll advise you based on your current system, so please feel free to consult us first.
Requests for estimates are also smooth as long as we know the vehicle model and your current audio situation.
