    JBL Only.. Non-JBL experienced folks need not apply....lol. totally kidding as you folks have a much easier go and i only wish i had the Non-JBL unit.

    So Looking for those who have ventured into the upgrade path while keeping the stock JBL head unit.. know there are post amp wires that need to be plugged into a processor to sum for a full range out... but wanted to chat with someone who has either O-scoped these signals and or know someone who has, just to educate myself.

    Know the folks at ********* have done something like this, but when i study their "Recurve" product offering and look at the wires going in, there are 8 input wires for FL-FR-RL-RR. So not sure where they are grabbing them from, but it would suggest that they are full range for front and full range for back... But they go on to say that the center channel is tied to the left dash speaker, as well, and you need to unplug the center speaker when calibrating the recurve and the output voltage is impacted by the load However, the Tundra wiring diagram (or at least the one I have) doesn't really show that.. Anyway, hence my question/request.

    Thanks in advance...
