100W amp draw on alternator

[gfl@cc.bellcore.com (grant f lenahan)]

the 80-100W amp should be no problem.  The "peak:average"
ratio of music exceeds 10 for most material, so, unless
its a class-A 100W amp (about the size of a steamer case),
its will only draw about 10W on average.  A 90A alternator 
is good for about 1KW - designed for your headlights,
strater, defroster, etc.  No problem.

(Do, however, try to avoid defrost, high beams, fog lights,
canked stereo etc all at once).
