Has anyone had experience with these? I have read that the scs line is the ones to get if any but was wondering what people have to say about the components in general.

Will be most likely looking at the 5.25" comp set possibly a 6.5" set.

Does anyone have any opinions on these components?

i used crystal components and subwoofers for about a year. in my opinion, they sound great. the speakers can't handle that much power, but as long as you don't throw a lot of wattage on them they should be fine
