【TH due Power Amplifier｜A High-Power Amplifier That Balances Strength and Finesse】

The TH due power amplifier is designed for anyone who wants music to sound more powerful—and to enjoy even the smallest nuances clearly.

With 300W×2ch at 4Ω stereo and 500W×2ch at 2Ω stereo, it provides ample output tailored to your system configuration. It can also deliver high output in bridge mode: 1,000W×1ch at 4Ω bridge and 1,500W×1ch at 2Ω bridge. Whether you’re powering the front speakers or looking to boost the drive power of the entire system, this is an amplifier that’s easy to consider.

Analog technology is used in the relevant sections, and it also supports Class A operation of 80W×2ch. I believe it’s a presence worth paying attention to—not only for the impact when you turn the volume up, but also for those who want to listen carefully to the fine expressions of vocals and instruments.

The crossover supports 3-Way. Using a removable module, you can set the high-pass, low-pass, and band-pass. In addition to the standard modules, it supports custom modules as well, allowing you to assemble the system in detail according to the speakers and subwoofers you’re using and the sound you’re aiming for inside your car.

However, having a high power output alone doesn’t automatically mean it will sound great. It’s important to balance the entire system—covering the power supply, wiring, the combination with your speakers, installation method, and adjustments of gain and the crossover.

If it were me, I wouldn’t choose the TH due as a standalone unit. I would first check your current head unit, speakers, and subwoofer configuration, and then decide which connection method and output will be best leveraged. Because it’s a large amplifier, the finishing results can differ based on installation work and tuning that match the vehicle and the system.

If you feel the current sound lacks power, that it becomes strained when you turn the volume up, or that you want to draw a bit more out of your speakers—let’s review and organize your direction together while checking your vehicle model and current system.
