Call Me Dubstep

Planning on going and getting wood today and starting the box build, i cut holes last night for 1/0 run to the back. Using some old thick rubber heater hose doubled up to create a grommet, put a bead of silicon around it to help seal / secure it. Father is helping me save money with some of this stuff so he came up with that, which he has done before. It was a pain to cut those holes.
