Punch Marine 500瓦 Class-bd 單聲道擴大機

Installed this in my boat's glove box and the conformal coated board gives me real peace of mind against splashes. It pushes my 10-inch sub cleanly without any heat issues, even after an afternoon of party tunes.

Ran it at full volume for two hours straight in the salt spray and it didn't even blink, that conformal coating is the real deal. The Class-bd tech keeps it running surprisingly cool for a 500-watt amp, so no overheating worries even with the cover closed.

Installed this in my boat’s console and the high dynamic power keeps up with even the heaviest bass tracks without a hint of distortion. The conformal coating gives me real peace of mind against the damp air, and it’s been dead reliable on the water for two months now.
