Problem is I just blew a speaker in my car with my new MP3 player laugh ($215 on ebay).

I've seen the following on Ebay:


confused Questions I have are:
1) What is a good power range?
2) Best set of speakers front/Back (1996 Contour SE)
3) My roommate has Orion Cobalt 260 amp (240 Watts RMS) with 2-6" MTX Road Thunder subwoofers
and I'm thinking about buying them. What is a reasonable price.
4) What is difference between 2-way and 3-way speakers? Which is better?

I know i'm asking alot, but thanks for the help.
I figure you guys are best place to come.

THANKS!
