SAFETY PRECAUTIONS
Fuse amplifiers power wire at the battery.
Be sure to fuse the power wire within 12” of the car's battery. This will protect the car's
battery in case of a short circuit between the power amplifier and battery. THIS IS A
MUST, the amplifier's built-in fuse will only protect the power amplifier not the car's
battery!
Usehighgradewireconnectors.
To ensure maximum power transfer and secure safe connections, it is recommended to
use high grade barrier spades (for connection at amplifier) and terminal rings (for
connectionatbattery).
Do not run any wires underneath vehicle.
Exposed wires have a chance of being cut or damaged. It is best to run all wires through
the vehicle under the carpet and/or side panels. This lends to a cleaner installation and
lessriskofdamage.
Usecautionwhenmountingamplifier.
Remember there are many electrical wires, gas lines, vacuum lines, brake lines as well
as a gas tank in the automobile. Make sure you know where they are when mounting the
amplifiertoavoidpuncturinglines, shortingwiresordrillingholesinthegastank.
Runsignalwiresawayfromelectricalwires.
To avoid possibility of induced noise from the car's electrical system (i.e. popping noises
orenginenoise), runwiresawayfromthecar'selectricalwiring.
Make all ground wires as short as possible and at the same point.
In order to reduce the chance of ground loops (i.e. engine noise), make the grounding
wire as short as possible to reduce the wire's resistance. Also, when using multiple
components, makesureallunitsaregroundedat the same point.
Avoidsharpedgeswhenrunningthewires.
To avoid the possibility of power, signal or speaker shorts, be careful not to allow the
amplifier’s wires to come in contact with sharp edges. Use a grommet to protect the wire
when running through the fire wall .

FEATURES AND BENEFITS
DC Offset Protection
This circuit protects the output of the amplifier against DC voltage. If for some reason DC
voltage is detected at the output stage, the amplifier will shut down protecting the
speakers from direct current.
Short Circuit Protection
The circuit protects the amplifier from damage due to a short found in the speakers or
wiring. If one of the speakers or its wiring comes in contact with ground, the amplifier will
shut down. To resume normal operation, correct the problem and turn the head unit off,
thenbackon. Theamplifierwillresetandplayagain.
Thermal Protection
To protect the amplifier circuitry against damage caused by prolonged exposure to high
temperatures, a thermal protection circuit is activated if the amplifier reaches excessively
high operating temperature. Once the thermal circuit is activated, the amplifier will shut
down to cool off. The amplifier will automatically turn back on once it cools down to a safe
operatingtemperature.
Power / Protect Indicator
The power L.E.D. Illuminates green when the amplifier is on and receiving power. The
protect LED Illuminatesredwhentheamplifierhasgoneintoprotectionmode.
Built-inCrossover
The Solar Series amplifiers include a built-in variable **high and low pass crossovers.
The crossover features a variable frequency selection (30Hz ~ 250Hz Low Pass and
60Hz ~ 1.2kHz High Pass ) for precise high or low pass filtering. **Except QS1500D
whichhasa 40~150Hzlowpassfilter.
BassEQ
For added low frequency performance the amplifiers are equipped with 0~12dB bass
boost @ 45Hz.
Stable To 2 Ohm Stereo Mode
The QS2150, QS2250, QS4150 and QS4250 are stable down to 2 ohms in stereo mode
and4ohmsinbridgedmode. TheQS1500D isstableto2ohms mono.

LineOut
One set of full range line outputs have been provided for convenient connection to
additionalamplifiersinthesystem.
Power Fusing
This protects the amplifier against short circuits and excessive current.
Remote Turn-on
Automatically turns amplifier on when connected to the head unit's remote output. The
amplifier will turn on and off with the head unit to save current consumption. This control
also operates the reset circuit for the amplifier's protection. It must be connected with the
headunitinordertoresetprotectioncircuits.
Adjustable Input Sensitivity
Allows you to fine-tune the level matching between your source and the power amplifier.

MOUNTING LOCATION
Before you start the installation, it will be necessary to find a mounting location for the
amplifier. Find a location in which the amplifier will receive adequate ventilation in order
to dissipate the heat it develops during operation. Two popular mounting locations are in
the trunk or under the seat.
Select the location in which you wish to mount the amplifier. Use caution when mounting
amplifier, there are many wires, gas lines, vacuum lines, brake lines as well as a gas tank
in the automobile. Make sure you know where they are when mounting the amplifier to
avoid puncturing lines, shorting wires or drilling holes in the gas tank. Once you are
ready, use a pencil to mark the mounting holes in the bottom panel. After you have
marked the locations of the holes move amplifier out of the way and drill small starter
holes to make the tapping screws easier to install. Use provided screws to tighten down
theamplifier.

IMPORTANT! Before making any connections, disconnect the car’s battery until the
installation is completed to avoid possible damage to the electrical system.
Connecttheamplifiertothecar'sbattery.
At times, the amplifier will need to draw large levels of current that cannot be provided by
any circuit in the car's fuse box. We recommend using a 4 to 8 gauge power wire for your
connections depending on the amplifier and length of the wire. Strip one end of the wire
and crimp on a barrier spade connect to the terminal on the amplifier marked “+12V”.
Loosen screw terminal and connect barrier spade and tighten (QS1500D uses bare wire
connection). Use caution to make sure no stray wire stands come in contact with
surrounding terminals causing short circuits. Run the wire directly to the positive terminal
of the car's battery. Make sure to use an in-line fuse within 12” of the car's battery to
protecttheelectricalsystemandamplifieragainstshortcircuitsand/orpowersurges.
Connectthegroundterminaloftheamplifiertothecar'schassis.
For the ground connection, use a 4 to 8 gauge wire (black) to connect to the terminal
marked “GND” and then connect it to the car's chassis. Try to keep the length of the
cable as short as possible, preferably less than 6". Also make sure that the point on the
car where the connection is to be made is free of paint and dirt.
Connecttheremoteterminaloftheamplifiertoaswitchable+12Vsource.
This connection allows the amplifier to be turned on and off with the power control of the
radio. If the radio has a REMOTE output terminal, connect it to the amplifier's terminal
marked “REM” (using a 16 gauge wire or heavier). Now when the radio is turned on, the
amplifier will automatically turn on. This connection can also be made to the radio’s
PowerAntennawire.

SIGNAL & SPEAKER CONNECTIONS
Connect the RCA output of the head unit (AM/FM cassette player, CD, or DAT) to
theRCAinputterminalsoftheamplifier.
To make these connections, we recommend high quality RCA cables, which are
available at your local car audio retailer. Run signal wires away from electrical wires to
avoid possibility of induced noise from the car's electrical system (i.e. popping noises or
engine noise). Please note that when making these connections the signal inputs
correspond with the speaker outputs.

Before connecting the remote, it will be necessary to find a mounting location that will be
easy to access for adjustment. Once you select your mounting location, you will need to
run the control wire from the remote to the amplifier. To avoid possibility of induced noise
from the car's electrical system (i.e. popping noises or engine noise), run the cable from

Subsonic Filter - On the QS1500D a subsonic filter has been
provided to filter out unwanted subsonic bass frequencies
below the audible range of the subwoofer . This feature helps
to improve the amplifiers overall performance since power
is not wasted reproducing frequencies beyond the speakers
operating range. This feature works in conjunction with the
Low-pass crossover to provide band-pass filtering.

ADJUSTING THE CROSSOVER AND BASS
.
The SOLAR series amplifiers are equipped with a built-in variable crossover network
allowing you to select the crossover type (i.e. Low-Pass or High-Pass) and the desired
crossover point. For example if you wish to drive a pair of subwoofers, you can select the
“Low Pass” setting on the amplifier to filter out high frequencies. This will send only low
frequencies to your subwoofers (see example settings below). The crossover point
should be determined by the speakers operating range. Please refer to speaker
manufactures recommended crossover point.
In this example we have selected
LPF (Low Pass Filter) for our XOVER.

FINE TUNE THE SYSTEM
Fine tune the amplifier's input sensitivity.
The input gain sensitivity control for the “Solar Series”
amplifier is located on the side panel. This gain control
has been included to allow adjustment to properly
match the output of the radio. This is one of the most
misunderstood adjustments. By rotating the control in
the clockwise direction, the amplifier‘s input will
become more sensitive and the music will play louder. This
5v .2v
is not a volume control and you will not get more power out of the amplifier in the
maximum position! It may seem to deliver more output, but actually the system is only
playing louder faster as you turn the volume control on the radio. Ideally, to properly level
match the system the goal is to achieve maximum output from the amplifier without
distortionatabout3/4ofthevolumecontrol.
Todetermineiftheamplifier’sgainissetproperly, turnthesystemonandslowlyincrease
the volume control. You should be able to use about 3/4 volume before the system gets
loud but not distorting. It is very important when making these adjustments that you do
not over drive the speakers (at point of distortion) this will cause permanent damage to
the speakers. If you are unable to achieve 3/4 volume before distortion you will need to
adjust gain control (in this case you would reduce the gain). The gain controls should be
adjusted very slowly. It may help to have another person to assist you by adjusting the
gaincontrolswhileyoulistenfordistortion.

TROUBLE SHOOTING THE SYSTEM
We have put together this trouble-shooting guide if you experience problems after
installing the amplifier. Please keep in mind that the majority of problems incurred are
caused by improper installation and not the equipment itself. In addition, there are many
components in the system that could cause various signal problems such as inducted
electrical noise and engine noise.
Before you can properly address the problem, you must first find the component that is
causing the problem. This will take patience and a process of elimination.
