500... TOUGH to do... NEARLY impossible to do WELL.
My recent "System Quote" (JL/ALPINE - ALL top end) was over $4500!
I'm going with "temporary" Memphis MC 6x9 "bi-ampable" coaxes in front and rear deck... until I get "serious" later in the year...
In the meantime, I'm using "OLD SKOOL" stuff laying around through the stock HU converted to line level... (The ALPINE IVA-205 isn't out till summer... and that's the one I want...)
Current set-up and costs:
STOCK HU - FREE! (JBL premium - '04 Solara)
MEMPHIS MC6x9's x 2pair - (A little over $200

special deal...)
WIRING - 4ga. 8ga. Power, Monster cable RCA's, Speaker, + blocks, fuses, Farad cap, etc... - $150ish
AMPS: Pioneer GM-H200 (300x1RMS), Kenwood KAC921 (100x2RMS), Orion SX-2125(125x2RMS)-OR-Infinity RSA-450 (225x2RMS) - FREE!
SUB - Infinity Reference Standard Pro-12 IMG (300x1RMS)
Anyway... with a little help from my OLD STASH and a "few" new temp. add-ons... (all install myself...)
I'm WELL BELOW your 500.... actually, UNDER $400 for an 11 speaker 800-1000 watt system! YAY for BUDGET MINDED enthusiasts!
Okay, so I "cheated" a little... the point is, to "finish" my system out with a "GOOD" Head Unit and PREMIUM stealth sub and component speakers (at least up front).... I'm looking at about $2000 over where I'm at... and THAT'S using my OLD AMPS! (They DO work GREAT, though... for "OLD SKOOL"

)
Best of luck with the 5-6 hundred dollar system... it's not "impossible", but VERY DIFFICULT these days...
