I wouldn't bother with the expensive model that interprets the bus signals. I'm yet to find a harness that will let me piggyback off the cig power without splicing the wiring.

I also ordered the PDX-5, and I hear a kicker solo 8" driver to replace the stock subwoofer, in the stock enclosure provides great results.

And depending on head unit, but my alpine unit has a light sensor which provides automatic dimming.

Also, how are you planning on powering your amp? Hooking into stock amp harness, or running better wiring?

I'll be honest, i wasnt planning on using ANY harness for the radio. Unless im mistaken, i should be able to simply tap into the existing remote, dimmer, and power supplies, correct? then run RCAs to the amp, and speaker/sub wiring from the amp to the rest...?
