AMPLIFIER

Mixed Mono Capable so you can simultaneously drive a stereo and mono

load (satellites and subwoofer).

2 Ohm Drive Ability

The Granite amplifiers are designed to drive loads

down to 2 Ohms stereo and 4 Ohms bridged.

Built-in Staggered Asymmetrical Crossover

Built in 2-way electronic

crossover is designed to send either high or low pass information to the

110.2. Outputs are included to drive another amplifier with either high or low

pass information.

Bass

Adjustable bass equalization circuit allows you to boost bass by as

much as

at 45 Hz. A built in subsonic filter protects speakers

(defeatable).

Drive Delay Muted Turn-on/off Circuit

A unique circuit which completely

eliminates any amplifier-related turn-on/off noises.

Flexible Input Sensitivity

accepts input voltages from 100 mV to 2.5 V.

which permits maximum output from amplifier with virtually any source unit.

“Balancing Act” Input Topology for added immunity to ground loops caused

by component and vehicle electrical system interaction.

WARRANTY

Your Granite amplifier comes with a limited warranty. Refer to the enclosed

warranty card for length of warranty and conditions.

WIRING

You will need the following tools for the wiring of the amplifier:

.Phillips or slotted screw driver

.wire strippers

wire crimpers

When baring the wires for connection to the amplifier, remove

3/8”

l/2”

of the insulation. For the speaker leads, use the supplied

l/4”

insulated female crimp connectors and slide the connector onto the

terminal on the amplifier. One 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 form the

chart below the minimum gauge power and ground wire required.

sure to fuse the amplifier positive power lead within

18”

of the battery.

up to 10’

12 gauge or larger up to 20’

gauge or larger

A. Carefully run the audio and remote turn-on cables to the

amplifier.

B. Connect the speakers as shown in “Speaker Wiring

Configurations.” Use at 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 amplifier. 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 below

for recommended fuse ratings to be used.

25 amp automotive 30 amp

D. Run a ground cable for the amplifier and securely connect it to a

solid chassis ground on the vehicle. The ground cable should be the

same gauge as the power cable.

E. Double check each and every connection!

TROUBLESHOOTING

PROBLEM

No sound and LEDs are not lit

Repeatedly blown amp fuse or

frequent activation of thermal

shut-off

CAUSE

no power or ground at amp

no remote turn-on signal

blown fuse near battery

blown power supply fuse

(accessible through access

cover on bottom of amp)

speaker or leads may be shorted

verify adequate cooling of the

amplifier

speaker load may be less than 2

Ohms

F. Re-connect the fuse or circuit breaker. 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 onto the time that the LED on the

amp lights. 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

.Use grommets when running cables through any metal or sharp

plastic to prevent accidental shorting or shearing.

.Be certain that the cables don’t interfere with normal operation of

the vehicle’s high current circuits and vehicle management

systems (engine computers, relays, etc.).

LEVEL SETTING

The input levels are adjusted by means of a stereo level control

located next to 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 control on the amp to a minimum position (fully

counter-clockwise).

B. Set source unit volume to approximately 314 of full volume.

C. While playing dynamic source material, slowly increase the

amplifier’s input level until a near maximum undistorted level is heard in

the system.

D. If you are using the amplifier to drive subwoofers, you may want to

use the bass boost circuit. First, engage the switch on the bottom of

the amplifier, secondly, slowly adjust the level on the front panel to

your preference.

PROTECTION CIRCUITS

Your Granite amplifier is protected against both overheating and short

circuits by means of the following circuits:

A main power supply fuse

A fail-safe thermal protection circuit activating at

85OC

Over-current Channel Circuit Breakers

Short-circuit shutdown

AMPLIFIER LOCATION AND MOUNTING

The Soundstream Granite 110.2 amplifier employs highly efficient

circuitry and a unique Chassisink

design to maintain lower operating

temperatures.

When

mounting the amplifier, it should be 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 freely-circulating air above and to the sides of it.

Before mounting the amplifier, make certain the amplifier is configured

correctly for your system.

BRIDGING/MONO

If used in dedicated mono, set the switch to the mono setting and

follow the wiring diagram below.

If used in Mixed Mono, set the switch to the stereo position and follow

the wiring diagram below.

BASS EQUALIZATION

If the Granite 110.2 is being used to drive a subwoofer, you may want

to activate the subwoofer equalization circuit by throwing the switch to

the “XXX” position. Activating the circuit also engages a subsonic filter

at 45 Hz. The subsonic filter is designed to remove the very low

frequency bass information that may damage subwoofers.

CROSSOVER SETTINGS

The Granite 110.2 can be configured to operate full range (for a set of

satellite speakers or coaxials), low pass (for subwoofers), or high pass

(for satellites or coaxials while another amp driving the subwoofers).

XXX DIAGRAMS XXX

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.

PASSIVE AND ELECTRONIC CROSSOVERS

Your Granite amplifier is capable of driving a complete subwoofer and

satellite system in the Mixed Mono configuration. However, for the

lowest distortion and the maximum output and sound quality, we

recommend you use electronic crossovers and multiple channels of

amplification. The Granite 110.2 amplifier incorporates an electronic

crossover with outputs. This amplifier, in conjunction with another

amplifier, will competently drive an entire bi-amplified system.

If you plan to use the Granite 110.2 in the Mixed Mono configuration, it

is important to use the appropriate passive crossovers. Below are

charts for 6 and 12 dB/octave crossovers.
