yea I'm running into the L7. sense the factory HU is staying in I need to extend the fiber optic cables to the trunk a long with a few other wires. my friend is a installer an seams comfortable with the job. I'm just trying to feel out where other ppl have had it done, how much, any tips, or problems. I'm surprised not many ppl are doing this upgrade an info is limited.
