be sure to correct these conditions before attem~tina

Your RIPPER amplifier was designed t o operate efficiently into 2 Ohm loads in the stereo mode. This means
that you can install four sr8- per'channd when using parallel wiring. Increasing the number
of woofer e at low frequencies (up to 100 Hz) produces an acoustic coupling effect. This
&c c e e s your power output by 3 dB per speaker.

When operating at 2 ohms, the amplifiers will increase their output power by approximately 50%. The current draw
r will also increase by about the same amount, so be sure you have enough current to run the amplifiers into a 2 ohm
load. If you lack adequate current, your music-repduction will be distorted.

e : gain control of any car audio amplifier should not be mistaken for volume control. It is
a sophisticated device, designed to match the output level of your audio source unit to the input level of
the amplifier. Do not adjust this input level to maximum unless your input level requires it. Ignoring these
instructions will result in a n input overload to the amplifier, and excessive audio distortion. It can also
cause the protection circuit to engage.

 Electrical Wiring
All BOSS power amplifiers are equipped with "easy-access" screw terminals. These terminals are nickel-
plated to ensure excellent electrical contact and resist corrosion.

When making electrical connections t o the amplifier, please observe the following:

Use at least 8 gauge or heavier wire for power and ground connections.

Connect the amplifier directly to the car battery.

For the ground connection, use the shortest possible wire to a good chassis ground point.

Wire the Remote connection to the remote turn-on lead of your equalizer or source unit (this is sometimes
also used as the power antenna lead).

I
Fuses
Power fuses protect both the amplifier and the electrical system of your vehicle from fault conditi~ns;'lf
you must replace the fuse in your RIPPER amplifier, use a fuse of exactly the same type and ratingr'k
different type or rating of fuse may result in damage or fire.
, -. . ..

Mounting the Amplifier

Mark the location for the mounting screw holes by positioning the amplifier where you wish to install it,
and use a scribe (or one of the mounting screws) inserted in each mounting hole to mark the mounting
surface. If mounting surface is carpeted, measure the hole centers and mark with a felt tip pen.

Drill pilot holes in the mounting surface for the mounting screws and insert the mounting screws into
these holes. Tighten them securely.

Note: Be sure to take note of any wires, lines or other devices in your vehicle which may be located behind
any mounting surface!

 High Level Inputs IRemote Subwoofer Level Control
If the HIGH LEVEL INPUTS are used, do not use the LOW LEVEL RCA INPUTS at the same time.
The RIPPER 2-Channel amplifiers use ONE HIGH LEVEL INPUT for both channels and the RIPPER
4-Channel amplifiers use TWO of these connectors one for each pair of channels.

Tri-Mode Operation is a unique feature which allows a subwoofer to be operated in MONO
mode, while the main speakers are playing in STEREO simultaneously on one pair of amplifier
output channels.

To engage the amplifier in this mode, place the Crossover (Subwoofer) switch in the "FUII' ,
positjon. Use a 1 OOv non-polar capacitor for a high pass crossover and a wire coil inductor
to block high frequencies from the subwoofer as shown in the figure below. Please review
the table below for inductor and capacitor component values to determine the desired .
crossover frequencies.

 Precautions
Before you drill or cut any holes, investigate your car's layout very carefully. Take care
when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring.

Do not operate the amplifier when it is unmounted. Attach all audio system components
securely within the automobile to prevent damage.

Do not mount this amplifier so that the wire connections are unprotected or in a pinched
condition, or likely to be damaged by nearby objects.

Before making or breaking power connections in your system, disconnect the negative
terminal of the vehicle battery. Confirm that your head unit and any other equipment is
turned off while connecting the input jacks and speaker terminals.

If you need to repla e-it-with a fuse identical to that supplied

with the s f l s i n g a fuse of a different type or ratiirg may result in damage to your
systA i c h i s not covered by the manufacturer's warranty.

 Troubleshooting
Before removing your amplifier, refer to the list below and follow the
suggested procedures. Always test the speakers and their wires first.

No Output Confirm that all terminal strip connections are secure and tight.

Check both in-line and built-in fuses. Both the "+I 2v" and the "~EM0TE"terminalsmust
have +12v referenced to chassis ground.

Confirm that the audio signal source (car radio, equalizer, etc.) is connected and is
supplying output signal. To check if the amplifier is supplying signal, unplug the RCA
cables from the signal source (but leave them plugged into the amp). Briefly tap the
center pin of each of the disconnected RCA plugs with your finger. This should produce
a noise (feedback)in your speakers.

Only one Confirm that all speaker strip connections are secure and tight.
channel
works Check the "BALANC~control on the head unit (or other source) to verify that it is set to
its midpoint.

If you are using the Low Level RCA input, reverse the input plugs at the amplifier (switch
the R with the L). If the channel which is silent switches to the other side, the problem is
either in the head unit/ other source or the connecting cables.

Weak output Readjust the Input Level Control to better suit the input signal.

Noise in the If the noise is a"whine" whose pitch follows the engine speed, confirm that the amplifier
Audio and any other signal sources (head unit, etc.) are properly grounded.

If the noise is a "clicking" or "popping" noise whose rate follows the engine speed, this
usually means that the vehicle is equipped with resistor spark plugs and wires, or that
the ignition is in need of service.

Check the routing of the speaker and input wires to make sure they are not adjacent to
wires which interconnect lights and other accessories.

If the above steps fail to improve or clear noise interference, the system should be checked
by a professional mobile audio installer.
