You will need to install an in-line fuse or circuit breaker in
the power wire within 18" of the battery. This fuse or circuit
breaker is to protect your vehic le from fire in case the po wer
wire shorts to the vehicle body. If you are only using one

amplifier, use the fuse rating indicated in this chart. If you are
using more than one amplifier, add up the fuse ratings for all the
amplifiers. This sum is the rating for your fuse or circuit breaker.
You may also want to add a power distribution block near your
amplifiers to keep the wiring tidy.

WIRING

Before beginning, disconnect the negative (-) terminal of the
battery prior to working on the positive (+) terminal to prevent
a short to ground. This is important, unless you want to spend
the rest of your life with a nickname like

"Sparky,"

Reconnect the negative terminal only after all connections have
been made.

Factory Ground wire may
need to be replaced if it is
frayed or broken.

Run signal cables (RCAs)
and remote turn-on lead
down the opposite side of
the vehicle from the power
wire to avoid radiated noise.

POWER / GROUND

Locate an area near the amplifier(s) that is metal and clean an
area about the size of a quarter to bare metal. Inspect the
area around and underneath to be sure you won't drill into wires,
brake or fuel lines, etc. Drill a pilot hole into the middle of this
area. Terminate the ground wire with a ring connector and attach
it to the bare metal using a #8 sheet metal screw and washer
or preferably, a bolt, nut and a star washer (not supplied). We
suggest crimping and soldering this connection. After the
connection is complete, coat the area (on both sides) with
silicone or some similar material to prevent rust from
developing on the bare metal.

POWER

Once you hav e run both the pow er and g round wires, it's time
to connect the cables to the amplifier . Cut off excess wire and,
using wire strippers, strip the ends of the power and ground
cables approximately 1/4 inch. Locate the

driver , loosen the screws before attempting to insert the cables.
Insert the wires into the appropriate hole, and tighten the
screws. Once the wires are secure, the

There are two sets of RCA jacks on the front end of your
amplifier. The RCA cables from your head unit go in the set
labeled INPUTS. If your head unit doesn't have RCA outputs
don't worry. Simply add a set of RCA plugs (available at your
dealer) to your front or rear set of speaker leads (see drawing
below), plug them into the input jacks, and push in the INPUT

This circuitry is capable of eliminating noise radiated into your
signal cables by up to 40dB. This is equivalent to a noise
reduction of approximately one hundred times what the noise
level would be without this circuitry . It provides all the benefits
of a true 'balanced' line without the need of any special cables
(see diagram below). This type of input works with any

conventional RCA cable .

AMPLIFIER ADJUSTMENT

Adjusting The Amplifier Input Gain

1. Adjust all amplifier input gain controls to just above minimum
sensitivity (fully counterclockwise).

2. Using the cleanest source (CD), with music playing turn up
the head unit until you can hear distortion. No w turn it down a
bit until you cannot hear the distortion.

3. Increase the Amplifier gain (clockwise) until the onset of
audible distortion. Then decrease the gain to the point just
before the distortion starts. This setting minimizes bac kground
noise and prevents overload.

4. Repeat step 3 for any remaining amplifiers in the system.

Bridging

All two-channel

POWERCLASS

bridged into a 4 ohm mono output without switches or bridging
modules. This feature permits the creation of a mono channel
for a subwoofer or center channel.

Deriving the mono channel is accomplished by using the left
channel positive wire as the positive speak er wire and the right
channel negative wire as the negative speaker wire. It is
important that a minimum 4 ohms impedance is obser ved. If
the impedance drops significantly below 4 ohms while the
amplifier is wired in the bridged configuration, the amplifier's
protection circuitry (AP III) may engage.

AMPLIFIER SHUTS OFF

Short Circuit Protection engaged:

The amplifier will turn off and try to come back on immediately. The
amplifier will cycle like this indefinitely, with "blips" of sound each
time. If this is the case, check your speakers and wiring for low
impedance and short circuits.

Thermal Protection engaged:

The amplifier will turn off and several minutes later will come back
on. In this case, ensure that there is nothing blocking the normal
convective airflow of the amplifier. No obstruction should be within
2" of the amplifier on all sides.

Mixed Mono Output

The ability to run stereo speakers while simultaneously running a mono
output from the same amplifier is accomplished by running the stereo
speakers normally and tapping into the appropriate wires for the "mixed
mono" channel (left channel positive for the positiv e speaker wire and right
channel negative for the negativ e speaker wire). Speaker impedance should
be no lower than 2 ohms on the stereo channels and 4 ohms on the mono
channel.

NOTE: Passive crossovers must be used for "mixed mono" operation.
Choose a low pass crossover around 100Hz for your subwoofer, then
choose a high pass crossover for your stereo channels. The high pass
crossover must be at the same or slightly higher frequency than the low
pass crossover to maintain the correct impedance. See your
dealer or call
