I've been reading up on the G37 forums and it seems that the Bose Headunit in their cars sends a flat Level Line to the factory Bose amp. The sound is processed and crossedover for each speaker from the factory amp. I wonder if this is the problem and i don't even need the Line Out Converter from the RE-Q. What happens when you convert a Line Level Out to a Line Level Out?

This so far makes the most sense since the input Wires were sheilded and wrapped vs. the the speaker wires that were just standard cable twisted together.
