Wow, I haven't checked back here for a while. I thought I'd update you guys on my final choice of setup. I went with the JL XD600/6 for the amp, and the Jehnert Flatlines for the speakers. I know there's some concensus that other options like the Morels perform better in some areas than the Flatlines, but in the end, the 'all-in-one' factor made me choose the Jehnerts. Also, I'll be mounting my amp and crossovers in the trunk, and laying new wiring for each connection between the amp and drivers.
I haven't installed them yet, so I can't contribute on how they sound, but I'm sure they'll be a fantastic upgrade from the Hifi that I have now!
