I have a 05 6s Hatch with bose. I have a sweet system I removed from my old car, which consisted of the front Tweeters (Infinity Kappa Perfect components) installed on-axis on the top corners of the pillars (corner of the windshield) pointed toward the center console. This sounds very good, gives a distinct full sound in the front, so I'd like to do the same in my M6. In my old car I had the speaker wire for the tweeter ran above the headliner, and down the back pillars to the crossover in the trunk. Has anyone had the headliner down in the 6? I notice there are rubber seals around the edges. I really just need to slip the wire along the edge of the headliner. Any tips on removal? Any help would be appreciated.
