Built-in Crossovers
All D-SERIES amplifiers feature built-in electronic crossovers.
The 2 Channel amplifiers(D400.2/D650.2/D1000.2) feature an adjustable low pass and high pass cross
-overs and +12dB variable Bass Boost.
The 4 Channel amplifiers(D350.4/D500.4) feature a pair of individually adjustable low pass crossovers
and high pass crossovers, as well as and +12dB variable Bass Boost.
All D-SERIES amplifiers have been designed with 100% MOSFET power supplies, ensuring extremely
quick switching response and self-protection.
Protection Circuitry
The amplifier protection circuitry will disable the amplifier if input overload ,short circuit or extremely high
temperature conditions are detected. When the protection mode is in operation, the LED indicator on the
front panel will be illuminated, indicating the amplifier has gone into a self-preservation mode.
If you observe that the protection LED is lit, please check the system carefully to determine what has
caused the protection circuit to engage. The amplifier can be reset by turning the remote power off and
then on again. If the amplifier shut down because of an input overload or short circuit, be sure to repair
these conditions before attempting to power up the amplifier again.
2 Ohm Operation
Your D-SERIES amplifier was designed to operate efficiently at loads down to 2 Ohms.
This means that you can install four 8 Ohm speakers per channel when using parallel wiring.
Increasing the number of woofers per channel at low frequencies (up to 100MHz) produces an acoustic
coupling effect. This acoustic coupling increases your power output by 3 dB per speaker, or the equivalent
of an additional 10W to each speaker.
When operating at 2 Ohms, the amplifiers will increase their output power by approximately 50%. The
current draw will so increase by about the same amount, also be sure you have enough current to
run the amplifiers into a 2 Ohm load. If you lack adequate current, your music reproduction will be
distorted.
Please note: The gain control of any car audio amplifier should not be mistaken for a 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 an input overload to the amplifier, and excessive
audio distortion. It can also cause the protection circuit to engage.

Electrical Wiring
All SOUND STORM LABORATORIES D-SERIES amplifiers are equipped with easy top access screw terminals.
These terminals are Nickel Plated in order to ensure excellent electrical contact, and to resist corrosion.
When making electrical connections to the amplifier, please observe the following:
Use at least 8 gauge or heavier wires for power and ground connections.
Wire 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 auto start lead of your equalizer or power antenna.
Fuses
Power fuses protect both the amplifier and the electrical system of your vehicle from fault conditions.
If you must replace the fuse in your amplifier, use a fuse of exactly the same type and rating. A 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 the 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!

Low Input / Line Output Wiring
If the HIGH LEVEL INPUTS are used, do not use the LOW LEVEL RCA inputs at the same time.
The 2-Channel amplifiers use ONE High Level input for both channels and the 4-Channel amplifier use TWO of
these connectors-one for each pair of channels.

Tri-Mode Speaker Wiring
Tri-Mode Operational Output is a unique feature which allows a Crossover (Subwoofer) to Be operated in
MONO mode, while the main speakers are playing in STEREO.
To engage the amplifier in this mode, place the Crossover (Subwoofer) switch in the "OUT"position. Use a
100v non-polar capacitor for a high pass crossover and a wire coil inductor to block high frequencies from
the Crossover (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 line and electrical wiring.
Do not operate the amplifier when it is un mounted. Attach all audio system components securely within
the automobile to prevent damage, especially in an accident.
Do not mount this amplifiers so that the wire connections are unprotected or likely to be damaged
by nearby objects.
Before making or breaking power connections in your system, disconnect the vehicle battery.
Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker
terminals.
If you need to replace the power fuse, only replace it with a fuse identical to that supplied with the system.
Using a fuse of a different type or rating may result in damage to your system which isn't 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 "+12v" and the "REMOTE" terminals must
have +12v referenced to chassis ground.
Confirm that the audio signal source (car audio, 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
channel
works
Confirm that all speaker strip connections are secure and tight.
Check the "BALANCE" 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 Sensitivity 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
and any other signal sources (head unit ,etc.) are properly grounded.
Audio
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 ignitions is in need of service.
Check the routing of the speakers 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.
