OWNER’S MANUAL &
INSTALLATION GUIDE
CONGRATULATlONS
You now own the Soundstream Granite Amplifier, the result of a unique design and
engineering philosophy.
To maximize the performance of your system, we recommend that you thoroughly
acquaint yourself with its capabilities and features. Please retain this manual and
your sales and installation receipts for future reference.
Soundstream amplifiers are the result of American craftsmanship and the highest
quality control standards, and if properly installed, should provide you with many
years of listening pleasure. Should your amplifier ever need service or replacement
due to theft, please record the following information, which will help protect your
investment.

CAUTION!
Prolonged listening at high levels may result in hearing loss. Even though your new
Soundstream amplifier sounds better than anything you’ve ever heard, exercise
caution to prevent hearing damage.

PASSIVE AND
Your Granite amplifier is capable of driving a complete subwoofer and satellite sys
tern in the Mixed Mono configuration. However, for the lowest distortion and the max-
imum output and sound quality, we recommend that you use electronic crossovers
and multiple channels of amplification, as provided in the Granite 120.4 and the
Granite 180.6.
If only two channels of your Granite amplifier are going to be used to drive a sub
woofer and satellite system, passive high and low pass crossovers will be neces-
sary. Use the following charts to determine the values of the crossover components.

LOCATiON
AND MOUNTING
Soundstream Granite amplifiers employ highly efficient circuitry and a unique
ChassisinkTM
design to maintain lower operating temperatures. When mounting the
amplifier, it should be securely attached to either a panel or to an amp board or
rack that is securely fastened to the vehicle, away from moisture, stray or moving
objects, and major electrical components (electrical motors, fuel pumps, etc.). To
provide adequate ventilation, mount the amplifier so that there are at least two
inches of freelycirculating air above and to the sides of it.
A. Using the amplifier as a template, mark the mounting surface.
B. Remove the amplifier and drill the holes.
C. Mount the amplifier to the surface using the provided hardware.
WIRING
You will need the following tools for the wiring of the amplifier: Phillips or slotted
screwdriver, wire strippers and wire crimpers.
When baring wires for connection to the amplifier, remove
insulation. For the speaker leads, use the supplied
l/4”
connectors and slide the connector onto the terminal on the amplifier. On the
power, ground and remote connections, loosen the screws on the terminal block,
slide the bared wire into the connector-and tighten the screw. Determine from the
chart below the minimum gauge power and ground wire required. Be sure to fuse
the amplifier positive power lead within 18” of the battery.

least 16 gauge speaker wire, preferably a flexible multi-strand cable, such as
Soundstream Speaker 120 or Speaker 160.
C.
Carefully run the positive power cable from the battery to a fuse or circuit
breaker and then to the
amplilier.
Connect the lead to the battery via either a
fuse or a circuit breaker within 18 inches of the battery. Leave the fuse out or
the circuit breaker off until the installation is otherwise finished. If the circuit
breaker cannot be shut off manually, do not make the final power connection to
it. See chart below for recommended fuse ratings to be used.

and every connection.
Power up the system and the red LED
should be lit. There may be a 2-3 second delay from the time that the source
unit is turned on to the time that the LED on the amp turns on. This is normal.
Once the amplifier power LED is on and the source unit is playing, you should
have sound coming from the speakers.
Wiring Tips
l Use grommets when running cables through any metal or sharp plastic to
prevent accidental shorting or shearing.
l Be certain that the cables don’t interfere with normal operation of the vehicle.
l Choose the location of the audii cables carefully to prevent interference with the
vehicle’s high current circuits and vehicle management systems (engine computers, relays, etc.).
LEVEL
SEHlNG
The input levels are adjusted by means of a stereo level control located to the left
of the input connectors. When the amplifier is operated in the mono/bridged
mode, only the right channel input is active.
A. Turn the input level controls on the amp to minimum position (fully counter-
clockwise).
B.
Set source unit volume to approximately
C.
Adjust outboard crossover and processor level controls so the output level of
3/4
of full volume.
the processor/crossover equals the input level. To do this, you can plug the
head unit outputs directly into the amplifier and listen to one amp at a time (at
low levels) to establish a reference, then add the crossover or processor and
set its gains to match the reference.
D.
While playing dynamic source material, slowly increase the amplifier’s input
level(s) until a near maximum undistorted level is heard in the system.
