sorry for late reply to your commentNot sure if i should quote myself or not, but no one has answered my questions yet. I have done a little more research myself today. One think I have found is it looks like PAC does not have software for Mac and JL does. That puts me leaning toward the Fix86. I downloaded their TuN software to play around a bit. I was under the impression that the Fix86 would do everything the amps with built in DSP would do but that does not seem to be the case.
if you like to send to me and pay for return and other costs.. i can make a harness for you ( Resistor , Speaker connectors etc etc... )
hope this helps
