Yeah... I got those posts... I have been looking into getting the pie multi-interface w/ 4-channel gain control to resolve the line level/gain issue... I have to look at the specs a little more...

I even have most of the parts I need to build the harness for the audio... not the male plug portion, but I figure I could find that eventually or else do an adhoc wrap of those eight wires. It's the annoying power interface that is bugging me...

I may have to go with the pro install of a new amp, but I want to make sure my other options are exhausted before I sink more big $$$ into this endeavor. -J
