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.
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!
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.
