Audio System X-170.4

The Audio System X-170.4 was developed for discerning car audio enthusiasts who expect maximum control, high power reserves, and audiophile-quality sound reproduction. Thanks to high-quality Class A/B technology with a FULL-MOSFET design, the power amplifier delivers a powerful, dynamic, and at the same time detailed sound. Whether it’s a high-performance front system, an active multi-way setup, or a powerful subwoofer system—the X-170.4 impresses with its enormous flexibility and impressive load stability down to 1 ohm per channel. The integrated crossovers, the Front Stage Adjuster, and the option for fully active operation make it the ideal choice for ambitious sound projects.
