my setup!! (see sig)
i have such amazing sound quality.. i cry everytime i hear a ballad.
but then my shiz also hits hard i think my back window is going to break

even though im underpowering my subs... the car audio guy in chico said my car hits as hard as 12s with twice the power... my hurts literally hurt and i have to turn it down or turn non-fader output down... but i love that i still have NO distortion.. just sound quality while that's happening.
headunits: eclipse, pioneer, alpine
subs: JL, ascendant audio's assassin, RE, plenty others
components: rainbow, high end focals, CDT, and crystal ssc6
rears: dont bother.. save money and upgrade others
i personally got my HU, amps, and subs for 1000$ but that's because i got a great deal.
id recommend 200$ components, $250 head unit, $200 sub(s), 400$ amps... well then you need a box which you can build yourself or have a shop do it for $150+. however i see that puts you over your limit by 200 heh.. ah well just estimate values anyways =P ah yeah and you need deadening.. if youre super crazy about sound quality then youll need that.
i dont want to pick out a full on system for you but i did give you a good guiding direction for what you should be looking for.
some of these brands you will not find in your local shop. but rest assured rainbows are TOP-notch components as well as CDT audio and cyrstal ssc6 will give you midbass like nobody's business with no distortion.
gl on doing your setup!
