Hey guys completely new to audio components and what not. I was wondering if people could put what they think a decent system would be (including cost) also how to decide what is decent quality in a market where there is a billion options. Obviously a top of the line build is not necessary as Im just getting into all this but want something that will sound nice and be a decent upgrade from the stocker.

Obviously Im expecting some flame on this because its so general so Lets just get passed that. Im just interested in maybe working on my car a different way then the visuals ive been doing and hoping you with a vastly large knowledge base will help a newbie in the field out!
