If ur looking quality its $$ but u can find some decent brands for not that much....if u want crap like ppl with distorting bass and speakers there's tons of crappy places that have the best deals lol
Start with a budget and then figure out what will give you the most for your money.
It's hard for people to recommend an audio set up for you, when you need to listen to various components of the set up to see what offers the best SQ for you/your music type.
