for $200, i say just buy a pair of pioneer 6x9s ($75 shipped) and a bobo amp to power them. I had a $135 Legacy amp (4x55w rms) and it sounded great because you get a lot of midbass. Some people thought I had subs. For your budget, I think that would be the best option. Then you can save up and upgrade, because if you get into car audio seriously, you'll eventually end up spending a lot of money on it.
