For a semi-permanent outdoor installation I need to waterproof a powered amplifier. (We opted against marine amplifiers for audio-input quality, and power-supply reasons)
What happens if I put a powered amplifier (2ch, 150W RMS per channel) into a water-tight, air-tight enclosure? The enclosure would be something like these waterproof Serpac suitcases, with waterproof cabling and connectors for sound in, sound out and AC in. Will the amplifier overheat? It has a fan, so it needs to circulate air. Would it work, if the enclosure is big enough, and the fan can circulate the air within the enclosure?
The enclosure will of course sit outdoors, so there is some natural passive cooling happening.
Anyone every tried that? Would love to hear some experience reports? Or if I am talking complete nonsense, please tell me so!
