I added some JL audio components in the door, JL audio coaxials in the rear hatch location, a JL Audio 6 channel amp, a JL audio 8" sub in one of their premade boxes and I'm using the new Sony DSX-S310BTX head unit. It's really cool. It has what they call a "tune tray", where the face folds down and you can plug an iPod or iPhone or USB memory stick in, then fold the face back up and you can't see it. You can still plug your iPhone into the front and use it for music, too. Plus it has bluetooth phone, streams Pandora, etc. Pretty slick setup. Very happy with how it all sounds.
