Help with set up.

I just bought a 2010 murcury milan. I want to get a system in it and id like to start with some subs. I like rock and metal. Some rap like eminem hopsin tech etc. But mostly rock and metal. Someone told me that the best subs for rock are 10s. I know nothing about subs, speakers, radios or any of it... I thought I did im my tweaker days. I just hooked junk to junk and thought it was the best in town. Anyways. Eventually I'd like to replace my stock strareo and speakers with something of excellent quality. Starting off I want 2 10s in the trunk with a switch to controll the bass volume. Like I said I like a little rap. What would be the best sub/amp combination to start with. Or your thoughts on my plan...
