Hello this is my first post here, I will be installing a new amp this weekend. I have an 08 TB with the BOSE system. My question is, do I have to install the LOC (line output converter) from the rear amp like in the sticky? Or can I install it behind the stock stereo? Ive never had to install a system and have to deal with a factory amp so I am kinda lost. Any help would be great.
