Audio like this all kinda depends on tast and preference, everyone is going to have a different opinion, but to me it all depends on price.
Lowest option buy a decent deck, and a good pair of 6x9's.
Next medium to high priced deck, good component system, and a 10 or 12 inch sub with amp to run it.
To get to the bottom of high end audio your going to want a very nice deck(rms doesnt matter from it because you wont use it anyways) two nice component systems, with a 4-way amp to power them both, and again one or two subs with proper power supplied.
As for brand buy what sounds best to you. I personally run kicker for everything and love it.
