Sub + Amp, how should i connect them?, Yes, another audio tread, tried the search already... Options

Hi!
I have the basic four speakers and no amp in my car. Now it is time to get an amp and a sub.
I don't know much about this stuff so I'm grateful for all help I can get. I'm right nog thinking about buying a 4 channel amp and connect two of the channels to the sub and the other two to my current speakers. Is this a good idea? Is it even possible?

Is there any big differents between 10" and 12" subs? I want a relative small sub so that i can use my trunk without takeing the sub out.

i would just have an audio shop do the installation so that way its sure fire the first time, but if its not then they should be able to fix it free of charge since they did it. i personally think 10's can slamm more than the same in 12's. just have to match everything i mean everything.
