CONGRATULATIONS
Thank you for choosing Precision PowerTM audio equipment. Designed and
engineered in the USA, this product combines innovative technology with
the finest materials to consistently deliver Absolutely State of the Art™ performance, sound quality, reliability, and value. This Precision PowerTM product
reflects our commitment to offer you unparalleled p erformance and quality
for years of dependable service and listening enjoyment.
SERVICE
Do not attempt to service Precision PowerTM products yourself.
Performing maintenance on your audio equipment will void the warranty.
Many parts of the Precision PowerTM product are custom built to our specifications. Our factory parts are not made available to anyone else nor are
they for sale. Our goal is to make sure that your Precision PowerTM product will
always sound as good as the day it was purchased. Contact your Authorized
Precision PowerTM Dealer about obtaining any warranty service through Precision PowerTM.
CAUTION
Extended use of a high powered audio system may result in hearing loss or
damage. While Precision PowerTM systems are capable of “Concert Level”
volumes with incredible accuracy, they are also designed for you to enjoy
at more reasonable levels all of the sonic subtleties created by musicians.
Please observe all local sound ordinances.

Installation
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.
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.
