Ground cable to
bare metal chassis/
frame with nut &
bolt. No screws or
seat/seatbelt bolts!
Avoid sharp edges
that could chafe
through the insulation.
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.
Run signal cables (RCA)
and remote turn-on lead
down the opposite side of
the vehicle of the power
wire to avoid radiated noise.
Factory ground wire may
need to be upgraded, espe-
cially if it is smaller than the
power wire, frayed, or broken.
Drill a hole in the firewall &
use a rubber grommet to
keep wire from shorting.
Fuse must be
installed within
18” of battery.

Installation
Before installing any audio equipment, it is good practice to disconnect the ground terminal on the battery to avoid dam-
age 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 bat-
tery until the rest of the wiring is complete.
