ok so i walked by the sony store today on my break, and i saw a deal where they were selling 4 subs for 130. This is all well and good but in doing so i would need to buy an amp and such. I know little about car audio, so i told the guy there that i just wanted a better sound system overall, he suggested an amp, and maybe new speakers depending on the quality of the ones that are stock. I was wondering how many watts the stock speakers are and what would be my best bet to improve my system. I really dont want a sub just yet because i dont want to take up space in my hatch. I have an '07 hatch btw. Would it be best to just start out with an amp and put it under the seat or what? any help would be great.
