Horizon HZ-600 600 Watt RMS Monoblock Amplifier

Sundown Audio HZ-600 | Horizon Series 600W RMS Monoblock Amplifier

Compact. Capable. Confident.

If you're looking for reliable bass power in a tight package, the HZ-600 delivers. Designed for efficiency and durability, this Class D monoblock amplifier pushes up to 600 watts RMS at 1 ohm, giving you clean, controlled output ideal for daily setups, budget builds, or adding a dedicated sub channel to your system. It's a true performer, offering more power than its size suggests — and doing it with Sundown's trusted engineering.

The HZ-600 features high-level input capability and DC Sense turn-on, making it perfect for factory integration or aftermarket installs where space is tight, but quality still matters. A built-in 12dB/octave low pass filter and subsonic filter give you precision control over your frequency range, while the 4-way protection circuit keeps your system safe from voltage issues, short circuits, thermal overload, and DC offset. And with the included wired remote, you get easy control of bass levels from the driver's seat.

Whether you're pushing a single sub or upgrading a factory system with a small footprint, the HZ-600 is built to deliver serious performance with no wasted power, no added fluff — just pure bass, clean and simple.
