Could someone explain the basics of car audio to me, or at least show me some sites which do that?

I understand that it is wise to have subs, good speakers a nice deck and amps, but I would like to know what the amps actually do. Do they make the subs pound harder?
Thanks

The key to car audio, is just like everything else, you get what you pay for. You buy a $5 pair of speakers, next week you'll be buying another $5 pair of speakers. Here's a site that will help you out as far as the basics go

They are also a good place to buy from, prices are a little high, but they have EVERYTHING, except extreme high end equipment.

I totally agree with knuck.

Not to mention when you find something you like go to Nextag.com and type in the model you like and there is a good chance you will find them signifinatley cheaper.
