D2's are nice because there are more amp options out there, and depending upon how serious you want to get, the D1's are nice, because you can make some big power.. I only use my stock alt as of right now, and have a Kinetik 2400 in the rear, along with my stocker up front. System consists of:
Head Unit - Pioneer DEH-P6900UB
Front Speakers - Kicker 6.5" Components
Rear Speakers - Powerbass 3XL 6.5" Components in rear door
4 Channel Amp - Interfire 400 watt
4 runs of 1/0 gauge
Kicker ZX2500.1 Amp
Subs - AQ HDC3 10's D1
Metered today at 146.9 @ 40Hz.
That's about it I guess?
