HOOKING UP THE AMP:
The amp’s main power lead needs to be connected directly to the battery. For safety reasons disconnect the battery’s negative wire from its post. Then using the supplied ring terminal, connect the power wire (usually blue if using an aftermarket kit) with the fuse holder directly to the battery positive post. Leave out the fuse until the install is complete and ready for testing. Run the power wire through the fire wall (look for pre-existing holes or routed wires that you can run it along). The power must be run on the opposite side of the signal (RCA) cables to prevent signal noise, which would sound like a dentist-drill in the background of the music. If there is no hole in your fire wall and you have to drill, make sure to avoid any of your car’s vital components.
