- (1) Sundown Audio 2-Ohm 4-Ch Amplifier SAE-200.4-V4
The Sundown Audio SAE-200.4-V4 brings back that fan-favorite Korean-style performance with a modern upgrade. This 4-channel Class A/B amplifier delivers a real 300W x4 @ 2 ohms RMS or 200W x4 @ 4 ohms, giving you up to 1200 watts of clean, usable power for a serious front stage, pro audio setup, or active system.
Built with an all-new chassis and 33% more aluminum in the heatsink, the SAEv4 runs cooler under load so you can play longer without thermal issues. The half-bridge design keeps the footprint compact while maintaining the stability and strong signal output Sundown is known for.
Dial it in your way with fully adjustable 12dB/Octave High Pass, Low Pass, and Subsonic filters (40Hz–5kHz). A built-in clipping indicator helps protect your speakers from distortion, and the 4-way protection circuit (thermal, voltage, speaker short, and DC offset) keeps your investment safe.
With a 92dB signal-to-noise ratio and up to 6V input sensitivity, this amp delivers loud, clear, and controlled power without the harshness.
If you want real Class A/B performance for your mids and highs without stepping into crazy pricing, the SAE-200.4-V4 is built to push hard and stay clean doing it.
