THANKYOU

Thank you for choosing Earthquake Sound's line of

mini

D amplifiers, the best way

to enhance your factory mobile audio system. With proper installation and

responsible listening, your amplifier(s) will give you years of near perfect sound

reproduction.

We strongly recommend you to have your new amplifier(s) installed by an

authorized Earthquake Sound dealer. Installation professionals employed by your

dealer have the correct tools and knowledge to install your amplifier(s) neatly and

successfully. Also, when your new products are installed by an authorized dealer,

your products will include a ONE (1) YEAR

L1MITED

WARRANTY. Ifyou choose to

perform your own installation, your warranty will be subject to further limitations.

Dealer policies on handling warranty requests mayvary from one dealer tothe next.

Please read the warranty information (Iocated at the end of this booklet) in its

entirety and usegoodjudgementwhen making these vital decisions.

INTRODUCING

mini

D nmpurlERS

The mini D amplifier series is the most efficient

c1ass

D series ever made, running

cool as they deliverunbelievable power despite

oftheir

compactsize.

Designed with the patented Optical Control Circuitry, each mini D amplifier comes

with a built in protection fuse which can handle 1 to

4-0hm

loads (it is most efficient

2-0hm

installation). Furthermore, the amplifier will automatically resets once the

protection circuit is triggered, unless the problem persists. Equipped with soft

clipping circuitry, these amps will not produce any audible distortion when

c1ipped

10%.

Eil,Hirm

The mini D amplifier series has a built in pre-amplifier that allows users to custom

design the frequency response and shape to their requirement. The pre-amplifier

stage includesthe following features:

Bass Boost-available on the D2000and D2500 modelsonly

The bass boost allows you to selectthe center frequency that you want to

boost as well as the quantity. For most application, the best setting is at %

turn (2o'clock position).

Variable Subsonic Filter

Subsonic filters are often used to protect speakers from harmful low

frequencies and DC voltage. Often clipped low frequencies could have

the same effect as that of DC input. The best setting for most system is at

30Hz Highpass.

LPF (LowPass Filter)

Often mistaken as crossover, the LPF is used to filter out unwanted mid

and high frequencies, leaving the woofer to response to low frequencies.

For most subwoofer application, the best crossing point is about %turn (2

o'c1ockposition).

Gain Control

Gain control regulates the amplifier'ssensitivity to match the signaIoutput

voltage of the audio source/head unit. It is not a volume control. The mini

Damplifiers have gain controls that are extremelysensitive and therefore,

should be adjusted with caution. When set at MIN, it will need 4V to clip

these amplifiers. But with a mere

'/4

turn, the amplifiers can clip with only

0.5V.

POWER LED: When lit up,the amplifier isfunctioning properly.

(])

PROTECTION LED: When lit up upon powering on, the amplifier may be in self-

test mode. Ifthis LED stays on, shut down the amplifier and locate what may

have triggered the amplifier to protection mode. If problem persists, cali us

for further assistance.

@ REMOTE SUB LEVEL: Used to adjust the amplifier's bass output fram a

location

ofyour

choice.

RCA INPUT: Low level inputs with range of

O.1V

to 5V RMS. Be sure to use a

HIGH LOW LEVELadaptor ifthehear unit has only speakeroutput.

®BRIDGE IN/OUT: Used when linking 2 amplifiers together. The BRIDGE

11\1

receives signal from the master amplifier and should only be used when the

amplifier is the slave amplifier (ali functions of the slave amplifier will be

adjusted by the master amplifier). The BRIDGE OUT sends signal to the

slave amplifier and should only be used when the amplifier is the master

amplifier. Note that

both

bridged

amplifiers

must

the same model

with

minimum

impedanceis

2-0hm

®GAIN CONTROL: Set based on the head unit's output voltage. Note,this is

not

volume

control. Always start at the MIN and slowly increase the gain.

Stop as soon as distortion is heard then lower the gain until the distortion

disappearand only

c1ear

sound is produced.

(])

LPF (LOW PASS FILTER): Used to filter out unwanted mid and high

frequencies.

®SUBSONIC FILTER: Used to protect the speakers from harmful low

frequencies and DC Voltage. The best setting for most system is at 30Hz (2

o'clock position).

CONNECTION:

These

terminals

have

been

internally

bridged/jumped. When connecting to both sets of terminals, there is a 2-

Ohm minimumimpedance

per

terminaI.

@ FUSE: Used as an added protection from damaging excessive current. Be sure

to use the proper fuse in your installation. Please refer to page 12 of this

manual for the proper fuse rating. Note that the

02000

and

02500

reguire

extemal fuses.

@ +12V BATTERY TERMINAL: Connect to battery positive (+) using a 4 gauge

cable.

@ REMOTE TERMINAL: Connect remote cable to the head unit's remote

terminaI. If multiple amplifiers are installed in the same system, additional

relays may be necessary.

®GROUNO TERMINAL: Connect to vehicle's chassis/ground using a short 4

gauge cable (2 feet maximumin length).

NOTE: Be sure to follow the wiring preparations/guidelines as Iisted on the next

page to ensure properinstallation.

0' Test the alternatoroutput. Factory alternators will produce 60 - 80 amperes at

best. Wearand heatwill reduce the output by40% .

0' Alternator ground (-) must be reinforced. Use a 4-gauge cable instead of the

factory8-gauge.

0' Alternatorpositive(+) to battery (+) must be reinforced.Use 4-gauge cables.

0' Checkyour batterycondition as batteriesdegradesafterawhole.

Battery(+) to amplifier(+) must be connected using a 4-gaugecable.

0' Ground amplifier to vehicle's chassis (bare metal) using 4-gauge cable, keep

the cable short (2feet max).
