I'm using a LC6 unit from audiocontrol (ebay is a good source) and seperate amps for the main speakers and a seperate amp for two Blaupunk thin subwoofers (to replace the Bose self powered ones). I am bypassing the car wiring completly (very easy). The LS6 will sit under the dash. RCA's for each channel will go through the trans console to the amp deck in the front of the luggage space (just a raised MDF platform covered with subwoofer cloth). I'm using a Tsunami AV cable (7 channels in one cable) to go directly back to the amps. From the amps foward I've run two audio cables to each door (the plastic trim is easy to pop out and fishing the cables to the door is also easy with a snake or a long spring claw) one for the subwoofer and one for the 3 1/2in midrange. I will run very short cables to each of the 5 1/2s in the back.
Note the back speakers are not full range and they are both on the same mono channel! Very poor fidelity from those two. I would not use the feeds for anything other than filler noise.
