Hi,
Its not simple at all when your talking big heatsinks. The rest of the time
looking at similar applications you usually need very similar heatsinks.

Look in the application notes in the data sheet for the LM3886 chip amp. Given is a relatively simple relation between maximum junction temperature and ambient temperature, and case and heatsink degrees C (or K) per Watt ratings. This is about as simple as it can be made, although the same heatsink will have a different C/W rating at each level of dissipated power.
Thank-you everyone ! While doing some further surfing I had found this > http://sound.westhost.com/heatsinks.htm < this seems to be well written in a form easy to understand.
