Punch Marine 500瓦兩聲道擴大機

Ran the wiring through a wet compartment all season and the conformal coated board still looks brand new, no corrosion at all. That Class-A/B punch is real too, plenty of headroom for my two tower speakers without breaking a sweat.

Installed this in my boat’s dash last weekend and the Class-A/B circuit stays cool even after an hour of cranking. The conformal coating on the board is a lifesaver for salty air, and the 500 watts pushes my two cabin speakers clean with zero distortion at high volume.

Installed this in my center console and the conformal coated board gives me real peace of mind against the constant salt spray. The Class-A/B amp pushes my tower speakers crisp even at speed, and so far zero issues after a month of weekend runs.
