Caution
High powered audio systems in a vehicle are capable of generating higher than "Live concert"
levels of sound pressure. Continued exposure to excessively high volume sound levels will cause
hearing loss or damage. Also, operation of a motor vehicle while listening to audio equipment at
high volume levels may impair your ability to hear external sounds such as horns, warning signals,
or emergency vehicles-thus creating a potential traffic hazard. In the interest of safety, TORO AUDIO
highly recommends listening at lower volume levels when driving.

Fig.1 Mounting Amplifier
Turn off all stereo and other electrical devices before you begin
Disconnect the negative (-) lead from your vehicle’s battery
Locate all fuel lines, brake lines, oil lines, and electrical cables when planning the install
Make sure there is at least 2-inches (5 cm) around the air vents on the amplifier.
When connecting ground points, make sure all paint is carefully scrapped away from the vehicle's
chassis and contact is make with bare metal
Use a utility knife to trim away fabric from hole locations before drilling or cutting
When running power cables through sheet metal, be sure to use grommets to properly insulate the
metal edges from the wire insulation
If possible, use tubing through grommets
NOTE: Proceed only if you are a qualified installer, otherwise; see your Authorized TORO AUDIO
Dealer or MECP Certified Installer to professionally install this amplifier. Always wear protective
eyewear when using tools.
Due to the high-power output of the TORO AUDIO RAGE amplifiers, considerable heat may be produced
when the unit is in operation. For this reason, the amplifier should be mounted in a location which will allow
air to circulate freely. A clearance of at least 2-inches (5 cm) to all sides of the amplifier is necessary not
only for proper cooling, but also for gaining access to the inputs and other variable controls. 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 malfunction.

Find a clear and well-ventilated area to mount your amplifier that is unobstructed by any objects that will
cause harm or block ventilation. Despite the fact that this amplifier is compact, it still needs air to cool the
heat-sink fins. Do not mount under a carpet or an area with dead or stagnant air. Without proper air flow
the amplifier may overheat and go into protection where the thermal overload circuitry will shut down the
amplifier.
You may use the amplifier as a template and mark the four screw locations with a felt tip pen. Set the
amplifier aside before drilling. Use caution to make sure there are no objects behind the installation surface
that may become damaged during drilling.
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. For
alternate installation locations, please consult your authorized TORO AUDIO Dealer.
NOTE: Do not use a drill with driver bit to mount the amplifier. Excessive force could cause the
plastic mounting feet to crack.
Upside down mounting will compromise heat dissipation through the heat-sink and
could engage the thermal protection circuit.
Try to avoid mounting the amplifier on a subwoofer enclosure, as extended exposure
to vibration may cause malfunction of the amplifier.
Don't mount the amplifier so that the wire connections are unprotected or are subject
to pinching or damage from nearby objects.
The DC power wire must be fused at the battery positive (+) terminal connection
before making or breaking power connections at the amplifier power terminals,
disconnect the DC power wire at the battery end.
The battery of the car audio system must be disconnected until the entire wiring and
installation is completed.
Do not use a power drill to tighten the power, ground, remote or speaker output
terminals on the amplifier to avoid stripping the terminal screws. It is best to hand
tighten these connections.
The use of Ring and Spade terminals (not included) provide the best electrical
connection for use with the clamp style connections on this amplifier.

TORO AUDIO Rage Mono Block amplifiers will draw large levels of current, so use the largest gauge power /
ground cable possible. Using too small of a power cable can result in unnecessary over-heating of the amplifier,
distortion at high volume levels and might even cause the thermal protection circuitry to shut-off the amplifier.
Remember, bigger wire and pure copper is better! For the best results we recommend a 100% Pure Copper
amplifier install kit available at your local TORO AUDIO dealer
Use rubber grommets when running cables through any metal or sharp plastic, to prevent accidental
shorting or shearing. Make sure the cables do not interfere with the normal operation of the vehicle
The audio signal cables (RCA Cables) should be kept far away from any potential sources of
electrical interference such as electronic vehicle management systems, relays, engine computers
wiring harnesses, fuel pumps etc.
FIG5. Power Input Connection
This amplifier is designed to work within a 9 to 16 volt DC range. Before any wires are connected, the vehicles
electrical system should be checked for correct voltage supply with the help of a voltmeter.
First, check the voltage at the battery with the ignition in the OFF position. The voltmeter should read no less than
12V. If your vehicles electrical system is not up to these specifications, we recommend having it checked by an auto
electrician before any further installation. Once the vehicle is checked, make certain the correct cable gauge is used.
We recommend using as large a gauge cable as possible, use the Power Cable Selection Chart to calculate the
correct power wire size for your application. Remember Bigger is Better!
18. HIGH PASS FILTER
SWITCH THE (HP) HIGH PASS FREQUENCY SWITCH FOR HIGH PASS FREQUENCY SET UP FROM FULL RANGE UP TO
3 KHZ BASED ON YOUR SPEAKERS AND SYSTEM SETUP REQUIREMENTS. SWITCH TO LOW/BAND PASS FOR A
VERSATILE BANDPASS SET UP FROM 20HZ TO 3KHZ OR SIMPLY A LOW PASS SET UP FOR SUBWOOFERS WITH SUB
SONIC CONTROL.
Remote 12V Output
USED TO CONTROL THE FREQUENCY BAND WIDTH (I.E.) WIDE WILL EFFECT MORE FREQUENCIES AND NARROW
EFFECTS LESS FREQUENCIES.

12V(Power)
This amplifier should be wired directly to the vehicle battery using the appropriate size cable. Start
at the vehicle battery and run the power cable through to the amplifier. Avoid running the power cable
over engine components and near heater cores. The use of an in-line fuse or circuit breaker is a
must; this will prevent the risk of a potential fire caused by a short in your power cable Connect the
fuse holder or circuit breaker as close to the battery positive (+) terminal as possible (no farther then
18" from that battery). This fuse or circuit breaker should be no greater than the sum of the fuses found
on the chassis of your amplifier (also see specifications chart). You may now connect the cable to the
battery, but remember to leave the fuse out or circuit breaker "off" until all other cable connections
are made.
When grounding your amplifier, locate a metal area close to the amplifier that is good source of
ground (preferably the floor pan). Once again, investigate the area you wish to use for electrical
wires,vacuum lines, and brake or fuel lines. Use either a wire brush or sandpaper to eliminate
unwanted paint for better contact of the ground.
Now it's time to connect the power and ground cables to the amplifier. Cut both cables to length.
Use a Phillips screwdriver to loosen the BATT+ and the GND connections on the amplifier. Insert the
ground first, and then the +12V and please make sure that you place them into the correctly marked
terminals. Then tighten the screws down securely.

REM (Remote Trigger)
FUSE REQUIREMENTS
While the panel on your TORO AUDIO amplifier incorporates one or more fuses, these do nothing
to protect the vehicle from a dangerous short circuit. It is absolutely vital that the main power lead to
the amplifier(s)in the system be fused within 18-inches(45cm) of the connection to the vehicle battery.
The value of this fuse (or circuit breaker) should be no greater than the sum of the fuses found on all
of the equipment being connected to that power wire.
This terminal must be connected to a switched +12V source. Typically, remote turn-on leads are
provided at the source unit that will turn on and off the amplifier in correspondence with the source.
If the source unit does not have a remote turn-on lead, then a switched +12V supply must be used,
like the ACC,+12V.
Run a minimum of 18-gauge wire from the amplifier location to the source of the switched +12V lead.
If possible, route this wire on the same side of the vehicle as your power cable. Connect the source
remote output to the wire. Go back to the amplifier and cut the wire to length. Loosen the screw
terminal marked REM on the amplifier

FIG6. Low Level Input using RCA
Choose the correct length and style of RCA interconnects for your needs. Always use high quality
RCA audio cables (not supplied) for signal connections--those with multiple layers of shielding or a
twisted pair variety provides better noise rejection.
Be extra careful when routing your RCA audio interconnect cables. Car environments are notorious
for poorly insulated wires. This means that hiss, engine noise, and fan noise can easily be picked up
through RCA cables if run incorrectly.
Make sure that the cables for power and audio signal are not on the same side of the vehicle and
that they do no cross each other; this will help reduce any noise that may radiate from the power
cable and the signal cable. If an audio 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.
