yep i use the black loom in my truck.
MOST of my interconnects are away from power cords as much as possible but most of my speaker cables seem to be pretty close to power cords.
i wouldn't think speaker to power would be as critical but just want to be sure.there sure do seem to be alot of cables accumulating and i have what would be considered a small system(with BIG sound in a small room).i dig it!
