Brenna, this is Bryan from Ben's Car Audio. We have done a Pioneer AVIC-N1 in a 2004 Xfire. We laso did a pretty hardcore alarm with tilt/motion senors and battery back up siren. We did a Bel radar/laser detector w/ diffusers. The Xfire was undectable to the radar and the laser.

We have located factory amps, and factory speakers sizes. We have not done the installation on ours yet. We are going to start the build after the CES show in January. We will take lots of pics and post them. As for your system, they are many different ways to go, depending on a couple of different things.

1. Budget
2. Looks
3. Sound Quality

Feel free to IM me or call, I can kind of guide you through the sales/design process and get you squared away. Depending on where you live I am sure we can find someone good to get you install done.
