Typical Installation
ALWAYS DISCONNECT YOUR VEHICLE’S BATTERY GROUND BEFORE WORKING WITH YOUR
VEHICLE’S ELECTRICAL SYSTEM.
ALWAYS BE AWARE OF THE LOCATION OF HIDDEN WIRES, CABLES AND FLUID LINES BEFORE
DRILLING HOLES OR MAKING CONNECTIONS.
1. DISCONNECT the negative battery post connection and secure the disconnected cable away from
the battery to prevent “accidental re-connection” during the installation process. This is not an
option. Just do it, Ben Franklin.
2. RUN power wire from the engine compartment to the amplifier installation location, taking care
to route it in such a way that it will not be damaged and will not interfere with vehicle operation.
Your amp will need to draw large levels of current, so use the largest gauge power/ground cable
available; we recommend at least 8 AWG. (See your authorized Polk AutoSound Dealer for power
cables and wire connectors.) Don’t forget to 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 25A fuses. Your “vehicle protection” fuse should be rated at 50A. (See your
authorized Polk AutoSound Dealer for professional advice on fuses and circuit breakers.)
3. CONNECT power wire with EMPTY fuse holder to the positive battery post. Do not install the
fuse itself until the power wire has been connected to the amplifier.
4. RUN signal cables and remote turn-on wire from the head unit to the amplifier mounting
location.
Use high quality RCA cables for signal connections. The remote turn-on connection allows the
amplifier to be turned on and off with the power control of your head unit. Use smaller cable
here, 16 gauge is probably best. (See your authorized Polk AutoSound Dealer for professional
advice on cables and connectors.)
Make sure that the cables for power and audio 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 an audio 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.
5. RUN speaker wire from the speakers to the amplifier installation location.
Measure enough wire to reach from your amplifier to each speaker or inline crossover, plus an
additional 12" to allow moving the speakers or equipment without having to disconnect the wires.
6. FIND a good solid metal grounding point close to the amplifier and connect the negative power
wire to it.
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.
DO NOT DRILL HOLES WHILE
THE AMPLIFIER IS IN PLACE
AS A “TEMPLATE.” YOU COULD
EASILY DAMAGE THE AMP’S
ANODIZED COATING BY
DOING THIS.
