Finally got around to installing everything. I'll take some pictures soon. As far a sound quality goes, this blows away the signal path through the head unit, even with CD as the source (and mind you I am using a Mobridge DA-2 to go straight from MOST to analog in the trunk). Zero hiss, crystal clear, and dynamics I have not thought possible coming from using Spotify as the signal source... Plain awesome!
