Installing Your New Polk Audio Amplifier

Notes About Electrical Installation

•ALWAYS DISCONNECT YOUR VEHICLE’S BATTERY GROUND BEFORE WORKING WITH YOUR VEHICLE’S ELECTRICAL SYSTEM.

•This amplifier is designed for use in vehicles with 12-volt, negative-ground electrical systems. Use of this product in vehicles with positive-ground, or with voltages other than 12 volts, may result in damage to the product and the system, and will void the warranty. This product is NOT certified or approved for use in aircraft.

•We recommend that you carefully design your car audio system before you begin a major installa- tion like this. Draw it all out. Make sure that the cables for power and signal are not on the same side of the vehicle and that they do not cross each other; this will help reduce any noise that may radiate from the power cable to the signal cable. If a signal cable is too close to a power cable, it may pick up the magnetic field generated by the power cable, which could lead to a loss of quality in your signal.

•Do not run wires under your vehicle or outside your vehicle.

•For best possible performance, give your power the widest possible throughway. Use the largest gauge power/ground cable available; we recommend at least 8 AWG. Use the largest gauge con- nectors, as well: barrier spades at the amp and terminal rings to the battery. See your authorized Polk AutoSound Dealer for power cables and wire connectors.

•Protect your vehicle with a circuit breaker or fuse placed no more than 12" (30cm) from your battery. This circuit breaker or fuse should be no greater than the fuse(s) of your amplifier for optimal protection. For example, this Polk Audio Amplifier has two 30A fuses. Your “vehicle pro- tection” fuse should be rated at 60A. See your authorized Polk AutoSound Dealer for professional advice on fuses and circuit breakers.

•Make your ground wires as short as possible to avoid Ground Loop engine noise and hum from interfering with your system. When using multiple components, ground everything at the same point.

•ALWAYS DISCONNECT YOUR VEHICLE’S BATTERY GROUND BEFORE WORKING WITH YOUR VEHICLE’S ELECTRICAL SYSTEM.

Installing Your New Polk Audio Amplifier

Before installing your new amplifier, carefully choose the location for the installation. The amplifier should have at least 2" (5cm) of ventilation space on all sides to allow heat to rise and dissipate away from the amplifier. Be sure that the power and signal cable connections can enter and leave the amplifier in a straight line to avoid the risk of kinked wires causing a malfunction. And try to make your ground connections as short as possible.

CAUTION: Remember, your car is filled with hidden stuff: electrical wires, gas lines, vacuum lines, brake lines and all sorts of other lines. Then there’s that pesky gas tank. You do not want to run into this stuff while drilling. Make sure you know where all of these dangers are when you’re installing your amp to avoid puncturing anything.

The amplifier should be protected from exposure to moisture and direct sunlight. The best places to mount your amplifier are: The floor of the trunk, under the driver’s seat, or on the back of the rear seat.

Once you decide where to install your amplifier and have made certain that there is ample ventilation, air circulation and shelter from unusual hazards, mark the mounting surface using the amplifier itself as a template. A tip: a strip of masking tape on these surfaces will help make your marks more visible.

Drill holes using a 1/8" (2.5mm) metal bit at the marked locations and mount the amplifier using the supplied screws and inserts. Take the time to secure the amplifier solidly so that it does not come loose in the event of a collision or sudden jolt to the vehicle. A flying amp will hurt you.
