OK, so you have all of your wiring in hand, capable to go. The next step is to take apart parts of one's vehicle. First, figure out where your wires can run. Which i run my Overhead Power line wire about the same side for this vehicle with regards to battery. Additionally usually run my RCA cables for the center of your vehicle. Knowing this information will tell you where you'll want to remove parts from automobile. If you're not destined to be running wires in a part of your vehicle, this won't be necessary for taking anything in addition to. UNLESS!! UNLESS!!! UNLESS!!!! You plan to put some sound damping material depressed. I always recommend this!

How do you know if the fuse is not good?
