I'm in the process of replacing all of the speakers with Infinity (62.11i 6.5" and 1031T tweeters) and adding an Infinity Basslink SM to the trunk space where the Bose subwoofer would normally live.

I'm planning on tapping the rear door speaker wires and running those to the Basslink, which will directly take a speaker-level signal. Since the 12V battery is right there, wiring the power will be easy, and the Basslink has an auto-on feature when it detects audio, so I don't have to run a remote turn-on wire. Should be a fairly simple install. Not sure how it will sound in that location, so that's my biggest concern at this point.

I've already replaced the tweeters and the front door speakers, and the change is pretty dramatic. I didn't bother running a separate amplifier, as the Kappas are pretty efficient and the head-unit seems to have enough juice to drive them.

Have you completed this? This is pretty much what I am planning on doing now, splicing into the rear speaker wires for high level input to my amp, but now I am trying to figure out the best way to get to the factory speaker cables to splice into them.

Yes, I've been running this system for a few months. I tapped into the wires behind the trim near the bottom of the B-Pillar, before the wires go into the door. There's a connector mounted to the frame there.
