Hey folks...long time no speak. I did this project only 4+ years ago. I used a metal box which already had vent holes in the sides. I also bought two 2" 12VDC fans but found that I ultimately didn't need to use them once I used a good amp.
Actually, my first amp was a cheaper model and it would overheat and cut off during the hotest part of the day as I discovered in the first hours of a cross-country road trip. I stopped at a Radio Shack enroute and bought the 2 12VDC fans to keep the amp cool. It helped but the thing would still overheat and automatically shut off at times leaving me musicless for minutes before it would come back on.
Once on the other side of the country, I exchanged the disappointing amp and upgraded to a better but more expensive brand and model (Pioneer, I think...I haven't even looked at it in some time...I just listen to it). I intended to install the cooling fans permanently after putting the amp in but, as it turned out, even though the new amp is bigger, it doesn't even need the cooling fans. It sits in it's box and has been working reliably now for nearly 5 years (I can't believe it's been that long!!!) and hasn't overheated once.
Hope this helps. :-D [addsig]
