Sean Clark shows us how to run the various cables for each peripheral. Get creative. Wires can be run in more places than you think. Remember to be careful when you're prying against plastic interior panels and use a cloth to protect them. Zip ties work wonders to attach components behind your dash. Make sure to allow enough space for HVAC vents when zip tying your items in tight spaces. Purchasing a wiring harness for your vehicle eliminates the need to splice factory wiring. One can easily tap into each speaker channel and feed to your aftermarket amplifier with a vehicle specific harness.
