Punch Marine 400瓦 4聲道擴大機

Installed this in my boat’s console and the Class-A/B output stays clean even when the engine’s running, no distortion at higher volumes. The conformal coating gives me peace of mind against the salt spray, and the 400 watts fills the cockpit nicely.

The conformal coated board was the main reason I picked this over cheaper options, and after a season of salt spray and humidity, it still looks brand new inside. Class A/B power gives it that punchy, clean output at low volume too, which my cabin speakers really appreciate.

Installed this in my boat’s console last weekend and it’s been running flawlessly through some choppy rides. The Class-A/B circuitry keeps the sound clean even at higher volumes, and that conformal coating is a lifesaver for peace of mind with all the salt spray.
