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

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!
