Does the AV8801 have a 12 volts trigger for the power amp, I don't seem to find this information anywhere.
Also if I put the unit in-wall, furnace room and it have lots of breathing space does it realy require a fan?
It would run 2 or 4 hours max since it would be for movie only.
It has 12 volt triggers and you may not need a fan on it but in my experience she does run warmer than other gear. I'm a firm believer that cooler runs more efficient and I've heard sound degradation in other gear I've owned from heat. Try it out but if it feels to warm on top throw a fan on it pulling the warm air out. I posted a link to one a few posts back that I really like, and threw a couple of rubber feet on it and it works like a charm.
