After a couple of months my system is almost done. Here's what I have so far.

Head Unit
Pioneer Premier DEH-P490ib with I-Pod adapter in glove box

Front Speakers
Infinity Reference 6020CS

Sub
MTX Thunderform Subwoofer and Box (10" MTX 4500 sub)

Amp
Sony 4 channel 600watt amp

The amp is running the Infinity speakers and the sub. I unhooked the sail panel speakers and left the rear hatch speakers connected. System sounds great, I'll probably add some mid-bass speakers to the sail area in the near future. I'll add pics later.
