Posted April 9, 200916 yr ... FINALLY WORKS!I rewired the LOC to the rear speaker wires past the factory amp instead behind the deck and it all works now! Apparently the radio puts out a signal no matter what, and the factory amp is what controls the volume. So that's why I was getting output at 0 volume.All I have to say is it sounds amazing! It gets the output and clarity I wanted and the 10 is loud, but beautifully crisp.Amazing products from the guys at FI.
