I've been researching this topic because this is where I'm at with my mods.
BriA5 from my350 says that his installer didn't have to use a LOC.
:quote from BriA5: My350z.com according to his installer
Bose does not make head units themselves. All their HUs are made by a few other companies. I am not sure who does the Z’s, but I want to say Alpine. Bose head units are constructed of two parts. One half is essentially a standard head unit, which produces line level outputs. The other half is a box which converts those outputs into the funky outputs which the Bose amps are looking for. Wires connect the two parts. My installer simply found those two wires between the pieces, stripped away the insulation, and soldered a wire that leads to my amps. This gives you the line level outputs you need.
The AudioLink PD-4 is basically a box that is the inverse of the second part of the Bose HU. While
it works well, the way this was explained to me I had to question why my installer’s method would not be better than taking a good signal, converting it to Bose standard, and then un-converting it back to its original form. Seems like there would have to be losses in that process.
Has anyone else done this?
