Ok so I need some help. I have a 2002 Monte Carlo ss with the onstar and factory amp and I'm wanting to increase overall sound quality. I have no idea what's good anymore as I've not kept up with the audio world for awhile. I'm looking to spend around $2-300. I know it's not alot but that's what I got at the moment. Just looking for some ideas if anyone could help. It's all factory and it sounds decent but I'm looking for a little better. Thanks in advance!
