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

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

This high-end power amplifier in a 4-channel configuration inherits the philosophy of BRAX’s renowned Matrix series. While carefully reproducing the position of vocals, the subtle expressions of instruments, and even the depth of sound, it firmly drives the speakers when the situation calls for it.

Using a Class AB topology, it pursues a simple circuit design with a shortened signal path. Rather than adding extra “flavor” to the sound, this amplifier draws out the information contained in the speakers and the recording—maintaining a balance between power and delicacy.

Inside, it uses MOS-FET switching devices, a large toroidal transformer, high-capacity custom capacitors, and more. It supports an output of 150W×4 at 4Ω and 240W×4 at 2Ω. It can be configured to drive the front and rear speakers together, or to bridge-connect two channels for greater driving power.

However, an amplifier isn’t “better” just because its output is higher. It’s important to think through everything—from the in-car speakers and subwoofers, the combination with OEM audio, how you handle the power supply, how it’s installed, and finally how you tune the sound. Even with the same GX2400, the direction of the final result will differ depending on which speakers you drive and what kind of music you listen to.

If it were me, I would first confirm what I’m dissatisfied with in the current system regarding sound, then organize where the GX2400’s driving power would be most effective before deciding on the configuration. I’d like not to add an expensive amplifier for its own sake, but to aim for a finishing result where, when you listen to your usual songs after installation, you think, “So much detail was in the sound all along.”

The overall quality will also change depending on how the power wiring and signal wiring are handled, how the amplifier is mounted, and how it’s 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 consider a reasonable, no-nonsense configuration that fits your car—together.
