I'm tired of listening to my crappy OEM speakers in my 94 accord lx. I have about $200 to spend and i want some good quality speakers. Im guessing that much will only get either the front 2 or back 2 replaced. Which are worth replacing first? What are some good speakers i could get for $200?

PS- I was lookin at some infinitys for the front and noticed they have standard speakers, and componant speaker systems. What are componant speaker systems?
