Installation

Before installing any audio equipment, it is good practice to disconnect the ground terminal on the battery to avoid damage

to the vehicle or audio equipment. Failure to do this means you’re a few brews short of a 6-pack and you probably

already acquired the nickname of “Sparky” or “Smokey”. Not cool! Do NOT hook the ground cable back up to the battery

until the rest of the wiring is complete.

Factory ground wire may

need to be upgraded, especially if it is smaller than the

power wire, frayed, or broken.

Run signal cables (RCA) and remote turn-on lead down the opposite side of the vehicle of the power wire to avoid radiated noise.

Avoid sharp edges that could chafe through the insulation.

Positive battery terminal

Fuse must be installed within 18” of battery.

Drill a hole in the firewall & use a rubber grommet to keep wire from shorting.

Run the cables under the carpet near the side of the vehicle. Be careful not to drill or screw into the wires when replacing trim.

Ground cable to bare metal chassis/ frame with nut & bolt. No screws or seat/seatbelt bolts!
