Phoenix Gold ZR12005

The Phoenix Gold ZR12005 is a compact 5-channel power amplifier designed for high-performance car audio systems. Thanks to the combination of four full-range channels and a powerful fifth channel for the subwoofer, a complete front/rear speaker and subwoofer system can be powered by a single amplifier.

The modern Class D circuit delivers high output power in a compact design with excellent efficiency. At 2 ohms, the ZR12005 delivers a total of 4 x 175 watts RMS plus 1 x 500 watts RMS. This means that the separate subwoofer channel, in particular, offers sufficient power reserves for more demanding bass systems.

To allow for flexible adaptation to the speaker system, the amplifier features adjustable high-pass and low-pass filters as well as a subsonic filter. In addition, the bass range can be boosted by up to 15 dB at 45 Hz.

Thanks to its high-level RCA input and automatic power-on function, the ZR12005 is suitable not only for aftermarket radios but also for integration into many factory-installed audio systems. A compatible remote control is included with the unit.

With a footprint of just 323 x 160 mm, the ZR12005 combines five amplifier channels with a space-saving design, making it particularly well-suited for installations that require high power in a limited space.
