I will problably be putting a fan on the bottom by raising the bottom, making a hole for a fan(3" to 4" like computer fan) that will be install in the bottom. And making a couple of holes on the side to vent the hot air and help keep the amps components cool.
A passive option would be best. I have often thought of ordering some heat sink and mounting it to the back where the hottest components are. This would be the easiest and should provide enough cooling for that amp.
I have since converted a pair of original MFWs to sealed to work with 4 other sealed MFWs for a total of 6. I'll say 2 or 4 sealed do a good job in my room down to 10, and 6-8 are perfect.
Converting these cabinets to sealed is pretty easy, I pulled amp and top circuit board sealed up holes and port slot inside. Net volume is a bit large I prefer the 2.5ft3 per driver I designed but the ~3ft3 per driver of the original MFW does fine. Excursion is less controlled than I like, I can't beat on them quite as hard as I can the ones I built.
Anyways its an option for those with multiples if you run out of amps. About 250W per driver is plenty. I don't think many people would be happy with just one sealed in any room.....
