STEALTH AMPLIFIERS
Thank you for your decision to purchase a STEALTH Series mobile amplifier!
Our Amplifiers are the result of extensive engineering, testing, and
bulletproof construction. Their versatility enables compatibility with optional
signal and audio processors. These high quality MOSFET amplifiers may be
configured to allow maximum flexibility in designing different types of speaker
systems.
The STEALTH Series are high quality MOSFET amplifiers that are capable of
running a system full range, or they may be selected only to power subwoofers. It is
important that you closely follow the wiring instructions contained in this Owners
Manual so that you get the most from your STEALTH Series mobile amplifier.
Some of our amplifiers are capable of producing a sound pressure level that can
cause permanent damage to your hearing system. High sound pressure levels
combined with long time listening can give permanent damage to your hearing
system. Choose a listening level that is comfortable for your ear. To establish a safe
level: Start your volume control at a low setting. Slowly increase the volume until
you can hear the music comfortly and clearly, without any distortion. Sudden
sound shocks are dangerous.

INSTALLATION PRECAUTIONS
NOTE: Proceed only if you are qualified installer otherwise, let your dealer do it.
Always wear protective eyewear when using tools
.

INSTALLATION PRECAUTIONS
•Turn off all stereo and other electrical devices before you begin.
•Disconnect the negative(-) lead from your vehicles battery.
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 auto body and contact is made 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.
MOUNTING THEAMPLIFIER
MOUNTING LOCATION
To keep your STEALTH Series amplifier running at top performance, choosing the
proper location it of utmost importance. 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 a malfunction.
Your STEALTH Series amplifier comes with mounting feet that need to be attached
to the amplifier prior to installation. Once the feet are in place, use the amplifier as
a template and mark the four screw locations. 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.

1. LINE IN (RCA)
The RCA style input jacks are for use with source units that have RCA line level
outputs.
A source unit with a minimum of 250mV is required for proper operation.
However, this input will accept levels up to 6Vrms.
2. High Level Input
If you are installing by using a high level . you do not need to connect to the
remote. To hear a better sound quality, you must connect the high level ground
wire to the head-unit ground.
3. Thru-Out
The LINE OUT allows you to build multiple amplifiers systems without having to
use splitter cords to distribute the signal. Now it is simply a matter of bringing one
set of RCAS into the fist amplifier, then using the line out RCA jacks as the feed to
the next amplifier.
4. Remote Bass Boost Control
This control adjusts the Bass Boost gain for the amplifier
*Packed product can be different from the photograph.
5. SPEAKER Coneector.
As shown in the wiring diagrams, be sure to observe speaker polarity through the
system and speaker impedance. This specially tooled terminal is designed to
accommodate p to 18 gauge speaker wire.
6. FUSE
For convenience all A STEALTH Series amplifiers utilize common automotive ATC
type fuses. For continued protection in the event that a fuse blows, replace the fuse
only with the same value.
7. Power Input Connector
This terminal is the main power input for the amplifier and must be connected
directly to the positive (+) terminal of the car battery.
8. Remote (Remote Input Connection)
All STEALTH Series amplifiers can be turned on by applying 12 volts to this
terminal. This can be found on the rear of the source unit in the form of an electric
antenna output, or a remote output.
If this is not available you can wire to the ACC position on the key. An 18 gauge
wire is sufficient to run the REMOTE.
9. GND (Ground Input Connection)
A good quality ground is required for your STEALTH Series amplifier to operate at
peak performance.
A short length of cable the same gauge as your power cable should be used to
attached the ground terminal directly to the chassis of the vehicle.

10.Power Indicator
The GREEN when the power is on.
11. GainAdjustment Control
The input level can be adjusted with this control. Turn it in the clockwise direction
when the output level of the car audio unit seems low
12. Sub Sonic Filter
Variable subsonic filter (20Hz ~50Hz)
The subsonic filter will roll off all of the unwanted frequencies below 20HZ ~50Hz.
This will allow the amplifier to use that wasted power on the audible bandwidth.
13. Low Pass Filter
STEALTH amplifier has an internal variable low pass filter. It can be set from 50 p
to 500Hz.
14. Bass boost level control
Turn this control to boost the frequencies around 45Hz to a maximum of 12dB.
15. Protection Indicator
When the PROTECTOR is activated, the indicator lights in red. When the
PROTECTOR
Is activated refer to the Troubleshooting Guide. (PPI Logo Badge)
16. High Pass ON/OFFSelector Switch
When the switch is in the ON position, the filter is set to High-pass. it is activated
High pass potentiometer control.
17. High Pass Filter
STEALTH amplifier has an internal variable High pass filter. It can be set from 50
up to 500 Hz. It also has that can be set from 500 up to 5KHz.
18. High Pass/Full/Low Pass Selector Switch
It is activated in each of the positions in top control.
