What's the diff and go with
 

K. So I'm a bit of a newb when it comes to determining systems. I DON'T want the crackling and garbage when I turn my sound up.

I'm debating no just replacing the speakers, getting one l7 sub. Maybe an l5. Not sure yet. And an amp that will support that.. If that is the way. What size speakers I need and what watt speakers should I be going with. Also what kind of amp.

Now another route is component. Is there really a difference?? I'm not to familiar with component speakers. Maybe I'm thinkin too into it and its the same thing.

Anyone can help me wit it? Thanks.
