Buying Components, Amplifer, Sub, and Coaxials

[NViejeP]

Hey guys, I'm fairly new to the whole car audio scene. I just got my first car aroune 2 weeks ago and I already took iniative and upgraded my head unit. There was a great deal at circuit city for a JVC. $30 off and then free installation.

Anyways, as soon as I save up, I'll be looking to buy

Components for my front powered to a 4 channel amplifer.
A sub powered to the 4 channel amplifer.
Coaxials in the back powered to my head unit (should I even bother? I heard these were just fill.)

But yah, I'm in the market for:
6.5 Components
4-Channel Amplifer
Subwoofer with box
4" Coaxials (Maybe)

All for my Toyota 4Runner. Can I please get some suggestions?

Oh, my budget is kind of limited. Right now I've got $100. But I plan on spending like $400-$500 eventually. Please note that I also have got to get these things profesionally installed. I might go beyond my budget because I plan on buying the components and amplifer, hooking those up and then getting the subwoofer last. Or I might just get the components first and then amplifer and subwoofer later on.

But yah, can I please get some suggestions on brands/models.

Thanks

get 6.5" separates in front.

Especially if you need this all installed, $500 isn't much. Start saving up.
