I removed both inside trim pieces along the door frame. One 12 foot phono pair goes from the left rear amp to the HU on that side. I made a 20 and a 15 foot twisted pair of 16 ga. tinned wire to run along the right side with the other 12 foot phono pair for the right amp which is for the front.
The speaker wires go through a rubber grommet that has a big bundel going through it behind the glove box. The wires come through behind a baffel near the
DSC piping. From there I went inside the baffel to the left side and through a rubber grommet to follow the factory wires to the side light and down to the rubber bellows (for lack of another description) covering the wires to the door. I made a small slit in the rubber on the door. (Look from the inside to see where to do this.) Before I inserted the wires in the door I slid on a 1 foot piece of black neoprene I skinned off a 3 wire cable to hide and protect the wires between the door and the engine space. The rubber on the door seals this well and it barely shows. I used a black wire tie to hold the new cable behind the rubber bellows.
Here are some pictures of the soundown treatment. By the way, the doors close and feel like a Rolls and the sound is unreal.
Here is the first stage of dampening.
