I do not have my truck yet so am only basing my assumptions on bits and peices I've gathered from various threads.

In short, I need to know if the nav voice and bluetooth phone calls only output from the front center channel? I'm concerned about the ability to retain bluetooth phone calls when adding a processor. I battled this with my previous vehicle and ended up taking all calls on my phone instead of handsfree.

The truck has the alpine sytem, and I am trying to determine where to grab signals for my processor to sum. From my understanding, neither the front and rear doors receive a full range signal with the 8.4 alpine setup. I would have to get signal from other areas. The dash speakers, and the front door speakers to maintain channel seperation, and the subwoofer for low frequency. Do the rear doors receive a signal that goes down to 20hz? If so, then I can forgo grabbing signal from the subs and get the center channel output.

If phone calls only go through the center channel, then to retain that ability I have to leave the center connected, which will conflict with all the aftermarket equipment that will be TA'd etc. when listening to music. Or I grab signal from the center channel and lose L&R signal since the processor only has 6 inputs if the rear doors do not get signal suitable for a subwoofer.

I could use another device to sum some of the signals and then use the processor to control the level and input other signals to sum since it can adjust levels of the inputs manually but that's a bad idea.
