Ok I am just a little confused on the component speakers. Is all I need a 6 piece set? Or do I need 2 of them? If I buy a 6 1/2 component set, then what else if anything would I also need to have in order to have a good sounding system without the immediate use of subs? I am planning on gettin just speakers and a head unit at first, and maybe later gettin 2 12s. Thanks for you help
