Trying to pick a system

if you want to go all one brand. i can think of a few things . alpine, eclipse,soundstream,and rockford fosgate. those are all brands that you could do a single brand install

alpine system

fosgate dosn' t make head unit anymore. dwarren is right once again . i agree the headunit and front stage speakers are what you hear and see the most ,and the quality of your head unit effects your entire system . i think demoing gear is much better than reading reviews

Steal this for a start to power your front components.  You won't go wrong with USacoustics amps.

Other notes:  if you're front components are going into the doors, use a lot of sound damping such as Dynamat or Raamat on both the outer skin and the door panel.  The high sub bass/ low mid bass sounds are crucial with rock music.  For your sub, use one sub suited for use in a sealed enclosure, a 12".  Power the sub with a separate mono amp.  If you're using rear fill speakers, too...buy two of those USacoustics amps.

(I'm always looking for closeouts on those amps.)

Oh, and this:  you might have plenty of money right now, but if you start buying without doing some good shopping that money will be gone fast.  Save out the necessary amount for the sound damping...that is critical.

For components you can look at Hifonics Atlas (the ones I have).  They are comparable to any $300+ components out there (JL, Alpine well they cost a bit less, etc.).  Got them for $95 (can't go wrong with the Hifonics).

Cheap Sound deadening (YOU WILL NEED THIS):

Walmart Undercaoting spray.

It is thick.  One coat is 75% the thickness of a regular folded paper knapkin (per coat).  At first I did not shake the can so it was coming out like paint (then I read the DIRECTIONS) and shook the can for 1 minute.  It came out textured and thick.  1 can can do 4+ coats on a door panel.  It dries pretty well in about 45 minutes.  I can definetley tell you it works.  I was driving today and normally cars pass you by and you can hear them (faintly), now they pass by and nothing is heard, this is also in 98 camry which is kind of quiet to begin with anyways.  Get this, you won't be dissapointed.  I'm getting more for the trunk.  WalMart $2.68 a can.
