I'm keeping the stock Bose head unit...what LOC would you guys recommend? I am wanting to tap into the wiring before the Bose amp in the trunk. I do not want to have something that taps in behind the head unit. (too much work to install).

Some have suggested the Navone NE-774V or Soundgate LOCPREA.

 

Bump. Wondering if anyone can share their experiences with LOC's..?

In regards to the post above, I would not recommend tapping the signal at the amp in the trunk. The signal wires are ran in the main harness and are bound to pick up some noise, despite being somewhat shielded. Getting to that amp is just as much work as getting to the back of the radio - you have to take all the left-side trim off (at lease on the coupe) which is a hassle. Also, you probably won't have much luck finding a mate for the Bose connector.

I'm considering the AudioControl LC6. I know the quality of engineering is very good for their products and it seems to be able to handle any kind of input. LOC's vary greatly in design and signal quality. You want something that will couple with the factory HU's output stage correctly and with minimal noise and distortion.
