Was up guys just picked up a 2010 c300 sport white black interior. First thing i did was install my subwoofer and amp. I couldnt find much help so i had to tackle it myself. I ran a scosche line out convertor i picked up from walmart $20 from behind the factory radio and ran the amp wiring down the passenger side. The scosche line out convertor had left and right speaker wiring. A amp remote wire. A ground wire and a 12v constant wire. It also came with bass controller knob. If i get enough request ill make a diy and show what wires i tapped and how i ran the wiring
