Here is what I would do and why:

Front: Focal KR3 - 3-way poly kevlar components (Incredibly loud and clear)
Amp: JL Audio 900/5 (Best HD Digital class amp money can buy)
Pre-Amp: Audio Control EQX (10Volt pre-out/13band parametric EQ)
Head: Alpine INA-900 (Burr Brown DA/Converters built in Nav)
Sub: JL Audio 12W6V2 or a 13TW5 (IMHO Hands down best subs made)
Rammat Sound Deadning the car completely plus Ensolite (Best Sound Deaning I have used yet)
Stinger DryCell battery (Best battery technology available, last 10 to 12 years)
JL Audio interconnects and amp wire (Best quality I have ever seen)

I would have custom door panels and pods to accomodate the 3-ways and build a custom subwoofer in the floor for the sub for Stealth. (The 13TW5 is perfect for stealth enclosure) A 12W6 will sound louder and better but at the expense of a large enclosure behind your seat. I personally chose the stealth option and I have plenty of bass.
