- Delivers 800W RMS per channel at 2 ohms, giving your system strong, clean, high-output performance for mids and highs
- Class D micro amplifier runs cooler and more efficient while fitting easily in tight installs without sacrificing power
- Bonded internal components and protective PCB coating help resist vibration, heat, and moisture for long-term reliability
- Fully variable high-pass and low-pass crossovers let you dial in your sound exactly how you want it
- High-level inputs with auto turn-on make it simple to connect to stock head units without extra wiring or adapters
DS18 NVY-i800.4 800 Watts RMS 4 Channel Class D 2 Ohm Powersport Amplifier
This Listing Includes:
- (1) NVY i800.4D 4-Channel Class D Amplifier
If you need serious power in a small footprint, this is it.
The NVY i800.4D is built to deliver clean, high-output performance without taking up space. Pushing 800 watts RMS per channel at 2 ohms, this amp has more than enough power to drive mids, highs, or even a full active setup with authority.
It’s not just about power though, this thing is built to last. The internal components are bonded for vibration resistance, and the PCB is coated to protect against moisture and corrosion. That means it holds up in real-world installs, not just on paper.
Setup is simple and flexible. You get fully variable crossovers so you can dial in your system exactly how you want it, plus high-level inputs with auto turn-on, making it easy to integrate into factory systems without extra hassle.
Efficiency is where this amp really shines. The Class D design keeps heat down and output strong, while the built-in cooling fan helps maintain performance when you’re pushing it hard.
On top of that, you’ve got full protection built in, including thermal, overload, short circuit, DC offset, and voltage protection, along with LED indicators for power, protection, and clipping so you always know what’s going on.
Small size, big output, built to handle real use.
