If you need real power for your sub stage without taking up space, this is it.
The NVY i1800.1D is built to deliver a solid 1800 watts RMS at 1 ohm, giving you the kind of output that actually moves air and brings your system to life. Clean, stable, and consistent, even when you’re pushing it hard.
This amp isn’t just about power, it’s built for real installs. Internal components are bonded for vibration resistance, and the PCB is coated to protect against moisture and corrosion. It’s made to last, not just look good on a spec sheet.
You also get full control over your sound. With adjustable crossover settings and bass boost, you can fine tune your low end exactly how you want it, whether you’re going for tight and clean or deep and aggressive.
Integration is simple. High-level inputs with auto turn-on make it easy to connect to factory systems, and the included remote level control lets you adjust bass on the fly without touching your head unit.
The Class D design keeps things efficient and cool, while the built-in fan helps maintain performance under heavy load. Add in full protection circuits and LED indicators, and you’ve got an amp you can trust every time you turn it up.
Compact size, serious bass power, built to handle it.
