Sundown Audio HZ-1500 | Horizon Series 1500W RMS Monoblock Amplifier
More Bass. More Control. All Sundown.
Designed for bigger builds and subwoofers that demand more, the HZ-1500 delivers up to 1,500 watts RMS at 1 ohm with low distortion and high efficiency. It’s the top dog of the Horizon Series mono lineup — made to push larger woofers or multiple drivers with clean, relentless power that stays cool and sounds tight.
Like its smaller siblings, the HZ-1500 features a robust 4-way protection system, DC Sense, and high-level inputs, giving you full flexibility for installs in both factory and aftermarket environments. Tuning is simple and precise thanks to the onboard low pass filter, subsonic filter, and included wired remote bass knob. You’ll have full control of your low end, whether you’re cruising or competing.
For builders and bass lovers who want one amp that hits hard, runs cool, and doesn’t take up half the trunk, the HZ-1500 is a no-brainer. It’s built the Sundown way — to deliver clean power, take abuse, and leave competitors in the dust.
