With my system going from the hu to the trunk I just went under the trim panels. Then when I was in my trunk went under the carpet. I mounted my box on had my 2 amps drilled on the box and then cut small holes right beside the box. Rand the wires up from there and used these things, I have no idea what there called, they have nails on both sides of it and stick out almost liek this [ so i could fit the wire under the opening. THen rand the wire up the box to the input on the amp. Looks really nice and clean that way!
Loud music is good... Loud music that is clear is better
