At what power ratings should one start to worry about this?


some people don't realize that if you have a fully regulated amp, you
get
little to no benefits. if it's un-or-semi regulated you may/can see
some
benefits

How do you figure? Headlight dimming would be more pronounced if anything
for a fully regulated amp.

no it wouldn't, fully reg. amps put less strain on elec. systems then
un-reg. amps.
