【Carrozzeria DEQ-7000A | 8ch DSP amplifier that tunes your sound while keeping the OEM navigation】

You want to keep your OEM navigation and head unit as they are. But even after replacing the speakers, the sound doesn’t come together the way you expected. You want the vocals to be a bit clearer. If that sounds like you, consider the Carrozzeria DEQ-7000A.

The DEQ-7000A integrates a DSP that lets you finely adjust music signals and an 8ch high-power amplifier in one model. While retaining the convenience of OEM audio, it can tune your music more naturally according to the in-car speaker layout and how sound reaches your listening position.

Improve sound cohesion without replacing the OEM navigation

In many recent vehicles, the OEM navigation or display audio is often linked with vehicle functions, making it difficult to replace the head unit purely for sound quality.

With the DEQ-7000A, you can keep using the OEM system and adjust the sound balance using time alignment, an equalizer, a crossover, and more.

When listening from the driver’s seat, the vocals seem to shift to one side; the bass sounds strong on its own; even after swapping speakers, the sound still feels scattered. This is exactly the kind of in-car listening characteristics that a DSP is designed to correct to match the vehicle.

Built-in 8ch amplifier—works with simple systems too

The DEQ-7000A features a built-in 8ch high-power amplifier.

You can control the front speakers separately for left and right, combine rear speakers and a subwoofer, and use it in ways that match your system configuration. Another advantage is that it’s easy to build a multi-amplifier setup without adding multiple external amplifiers.

Of course, it’s ideal to install at the same time as replacing your speakers, and it’s also a good fit if you’ve already replaced speakers but want to take the sound up one more level.

Fine-tune from your smartphone or PC

It supports a dedicated adjustment app, allowing you to configure sound settings from your smartphone or PC.

Using time alignment, a 13-band equalizer, a crossover, and more, you can adjust sound imaging, the connection of the bass, and how vocals come across. Since it also supports Bluetooth connection and USB-DAC input, it’s a convenient setup for people who usually listen to music on a smartphone or DAP.

However, because a DSP offers a wide range of adjustments, the final result will vary depending on your settings. It’s not simply a matter of entering numbers and being done—it's important to tune while actually listening in the vehicle, taking into account your speakers and the vehicle conditions.

To get the most out of the DEQ-7000A, installation and tuning are key

A DSP amplifier isn’t a product where the sound is finished just by installing the unit.

Depending on the connection method with the OEM audio, the speaker configuration, whether you have a subwoofer, how power and wiring are handled, the installation location, and more, usability and the final sound will change. You need to consider what kind of system you’ll build, including the tuning after installation.

At LOGON, we guide you through whether installing the DEQ-7000A makes sense, while confirming your vehicle model and OEM system, your current speaker setup, the music you typically listen to, and your sound preferences.

Even with the same product, impressions can differ depending on where and how it’s integrated and how far you tune it. It’s a DSP amplifier that can be the starting point for reviewing your entire system—especially for those who want to keep the OEM navigation, improve sound cohesion, or consider the next step after replacing their speakers.
