【BRAX GX2400 Long Silver｜4-Channel High-End Power Amplifier】

You want to be particular about the amount of musical information and imaging, but you may worry that adding an amplifier will make the sound feel harsh or change the overall atmosphere of the music. If so, you should consider the BRAX GX2400 Long Silver.

This is a high-end power amplifier with a 4-channel configuration that inherits the philosophy of BRAX’s longstanding Matrix series. While carefully rendering the vocalist’s position, the subtle expressions of instruments, and even the depth of the sound, it drives the speakers firmly when needed.

Adopting a Class AB configuration, it pursues a simple circuit design that keeps the signal path short. Rather than adding any extra flavor to the sound, this amplifier extracts the information contained in the speakers and the recording—maintaining a balance between power and delicacy.

Inside, it features MOS-FET switching devices, a large toroidal transformer, a high-capacity custom capacitor, and more. It supports outputs of 150W×4 at 4Ω and 240W×4 at 2Ω. It can be configured to drive the front and rear speakers together, or to connect two channels in bridge mode to provide even greater driving power.

However, an amplifier isn’t simply “better” because its output is high. It’s important to consider the entire system, including the in-car speakers and subwoofer, combinations with factory audio, how you take power, installation methods, and the final sound tuning. Even with the same GX2400, the overall direction of the finish will differ depending on which speakers you drive and what kind of music you listen to.

If I were designing your system, I would first check what dissatisfaction you currently feel about the sound, then organize where the GX2400’s driving power would be most effective before deciding on the configuration. Rather than aiming only to add an expensive amplifier, I’d like to achieve a result where, when you listen to your usual tracks after installation, you think, “So much information was in the sound after all.”

The final quality also changes depending on how power wiring and signal wiring are handled, how the amplifier is secured, and how it is combined with surrounding components. If you’re interested in the BRAX GX2400 Long Silver, please tell us about your current vehicle system and the sound you want to hear. Let’s think together about a realistic, no-nonsense configuration that fits your car.
