OWNERS MANUAL

SQ FULL RANGE DIGITAL AMPLIFIER

∆Caution ∆

High powered audio systems in a vehicle are capable of generating

higher than “Live Concert” levels of sound pressure. Continued ex-

posure to excessively high volume sound levels could cause hearing

loss or damage. Also, operation of a motor vehicle while listening to

audio equipment at high volume levels may impair your ability to hear

external sounds such as horns, warning signals, or emergency vehicles—

thus creating a potential trafﬁc hazard. In the interest of safety,

Image Dynamics USA highly recommends listening at lower volume levels

when driving.

INSTALLATION EXPERIENCE

Installation of Image Dynamics mobile ampliﬁers requires detailed knowledge of electron-

ics wiring and proper speaker impedance. We strongly recommend installation by an

authorized Image Dynamics dealer. This Owners Manual only provides general installa-

tion and operation instructions. If you have any reservations about your installation skills,

please contact your local Image Dynamics dealer for assistance.

IMPORTANT : This ampliﬁer is designed for operation in vehicles with 12-volt Negative

ground electrical systems only.

PREPARING FOR INSTALLATION

NOTE: The tools listed below may be required for basic installation

• An electric drill with bits

• Philips head and standard screwdrivers

• Wire strippers

• Crimping tool

• VOM (electronic volt ohm meter)

• Heat shrink tubing and heat gun

• Soldering iron

• Electronic (Rosen not Acid Core) Solder

INSTALLATION PRECAUTIONS

NOTE: Proceed only if you are a qualiﬁed installer, otherwise; see

your Authorized Image Dynamics Dealer to professionally install this

ampliﬁer. Always wear protective eyewear when using tools.

• Turn off all stereo and other electrical devices before you begin.

• Disconnect the negative (-) lead from your vehicles battery.

• Locate all fuel lines, brake lines, oil lines, and electrical cables when planning the

install.

• Make sure there is at least 2-inches (5 cm) around the air vents on the ampliﬁer.

• When connecting ground points, make sure all paint is carefully scrapped away from

the auto body and contact is made with bare metal.

• Use a utility knife to trim away fabric from hole locations before drilling or cutting.

• When running power cables through sheet metal, be sure to use grommets to prop-

erly insulate the metal edges from the wire insulation.

• If possible, use tubing through grommets.

WARNING: Check your vehicle’s owner’s manual before disconnecting

the battery. Disconnecting the battery on some vehicles may require

an anti-theft code when reconnecting the battery and require the on-

board computer to be reset at the dealership. Check with your local

dealer if you are uncertain.

To keep your Image Dynamics running at top performance, choosing the proper location

is of utmost importance. Both Thermal and Overload protection are built in. In the event

of overheating, the ampliﬁer may temporarily shut down operation. For this reason the

ampliﬁer should be mounted in a location which will allow air to circulate freely.

MOUNTING LOCATION

Find a clear and well ventilated area to mount your ampliﬁer that is unobstructed by any

objects that will cause harm or block ventilation. Despite the fact that this ampliﬁer is

compact, it still needs air to cool the heatsink ﬁns. Do not mount under a carpet or an area

with dead or stagnant air. Without proper air ﬂow the ampliﬁer may overheat and go into

protection where the thermal overload circuitry will shut down the ampliﬁer.

NOTE: Make sure not to block the cooling fan (SQ-1400.5 only)

The ampliﬁer should be protected from exposure to moisture and direct sunlight. The

compact size of the ampliﬁer allows greater ﬂexibility in mounting. The best places to

mount your ampliﬁer are: The ﬂoor of the trunk, under the driver’s seat, or on the back of

the rear seat. For alternate installation locations, please consult your authorized Image

Dynamics Dealer.

If mounting under a seat, make sure there is at least 1-inch (2.5cm) of space above the

ampliﬁers heatsink to permit proper cooling.

You may use the ampliﬁer as a template and mark the four screw locations with a felt tip

pen. Set the ampliﬁer aside before drilling. Use caution to make sure there are no objects

behind the installation surface that may become damaged during drilling.

NOTE: Do not use a drill with a driver bit to mount the ampliﬁer. Ex-

cessive force could cause the plastic mounting feet to crack.

FUSE REQUIREMENTS

While the panel your Image Dynamics ampliﬁer incorporates one or more fuses, these do

nothing to protect the vehicle from a dangerous short circuit. It is absolutely vital that the

main power lead to the ampliﬁer(s) in the system be fused within 18-inches (45cm) of the

connection to the vehicle battery. The value of this fuse (or circuit breaker) should be no

greater than the sum of the fuses found on all of the equipment being connected to that

power wire.

SQ1400.5- 100 Amp Fuse

SQ800.4- 60 Amp Fuse

NOTE: Due to space limitations, the SQ 1400.5 does NOT use chassis

mounted protective fuses. Therefore you must add a fuse and fuse hold-

er (not included) rated at 100A for each SQ 1400.5 installed.

*** WARNING ***

• Do not install in a place where it could injure the driver or passengers if the vehicle

stops suddenly.

• Upside down mounting will compromise heat dissipation through the heatsink and

could engage the Advanced Protection Circuitry.

• Try to avoid mounting the amplier on a subwoofer enclosure, as extended exposure to

vibration may cause malfunction of the amplier.

• Don’t mount the amplier so that the wire connections are unprotected or are subject

to pinching or damage from nearby objects.

• The DC power wire must be fused at the battery positive (+) terminal connection. Before

making or breaking power connections at the amplier power terminals, disconnect the

DC power wire at the battery end.

• The battery of the car audio system must be disconnected until the entire wiring and

installation is completed.

CONTROL PANEL LAYOUT

NOTE: Panel Layout and Controls may differ by model.

1. Line Input Switch (SQ800.4 only)

This switch will let you use a single pair of RCA inputs to run all 4 channels of the ampliﬁer or have

2 pair of RCA inputs to run all 4 channels of the ampliﬁer separately. The SQ1400.5 has a subwoofer

input selector button that allows the input signal to be taken from the Rear Channel if selected. If the

subwoofer input button is selected at the Sub position, then a dedicated input needs to be used.

2. Line INPUT (RCA) Jacks

These RCA style input jacks are for use with source units that have RCA line level outputs. A source

unit with a minimum of 250mV is required for proper operation. However, this input will accept levels

up to 10 Vrms.

3. FRONT and REAR GAIN Control

This control is used to match the input sensitivity of the ampliﬁer to the particular source unit that you

are using.

4. FRONT and REAR BASS EQ Switch for 0dB/9dB/18dB (SQ800.4 only)

This equalization circuit is used to enhance the low frequency response of the vehicles interior and

only works with LPF setting ON. Selectable to 0dB (ﬂat) or 9dB to 18dB of boost centered at 45Hz, the

BASS EQ switch can be selected to meet your own personal tastes. Remember, more is not always

better.

Fig.2 Panel Layout

5. FRONT and REAR LPF (Low Pass Filter) 40 Click Detent Control

This control is continuously adjustable from 30Hz through 300Hz at 12dB per octave.

6. FRONT and REAR X-OVER Switch for LPF/FULL/HPF (SQ800.4 only)

Activates the built-in electronic crossover network. Works in conjunction with the LPF and HPF adjust-

able controls. When set to FULL, the two variable controls marked HPF and LPF have no effect on the

ampliﬁers output.

7. FRONT and REAR HPF (High Pass Filter) 40 Click Detent Control

This control is continuously adjustable from 50Hz through 300Hz at 12dB per octave.

8. POWER/STATUS Indicator

The clear LED lights Blue when the power is on—or turns Red constantly when the built-in protec-

tion circuitry is activated. Red indicates a problem with the system in relation to the ampliﬁer. (See

Troubleshooting Tips on pg 25)

9. SPEAKER Output Terminals

This specially tooled solderless terminal block is designed to accommodate up to 10-gauge speaker

wire. Please refer to the wiring diagrams in this manual and be sure to observe speaker polarity and

impedance throughout the system.

10. FUSE(S)

For convenience most Image Dynamics ampliﬁers utilize common automotive ATC type fuses. For

continued protection in the event that a fuse blows, replace the fuse only with the same value (see

speciﬁcation table). CAUTION: These power fuses on the ampliﬁer chassis are for protecting the amp

against overdrive. To protect the vehicles electrical system, an additional fuse should be used within

18-inches of the battery on the 12V+ cable.

SQ1400.5 100A (Requires external fuse - not supplied)

NOTE: Due to space limitations, the SQ1400.5 does NOT use chassis

mounted protective fuses. Therefore you must add a fuse and fuse hold-

er (not included) rated at 100A for each SQ1400.5 installed.

11. BATT+ (Power Input Connection)

This solderless terminal is the main power input for the ampliﬁer and must be connected directly to the

12-volt Positive (+) terminal of the car battery. The terminal can accept up to 4-gauge wire (see Power

Cable Selection Chart for the minimum recommended wire gauges).

12. REM (Remote Input Connection)

All Image Dynamics ampliﬁers can be turned on by applying 12 volts to this terminal. This can be

found on the rear of the source unit in the form of a remote output. If this is not available you can wire

to the ACC position on the key. An 18 gauge wire is sufﬁcient to run the REMOTE.

13. GND (Ground Input Connection)

A good quality ground is required for your Image Dynamics ampliﬁer to operate at peak performance.

A short length of cable the same gauge as the Power cable should be used to attach the Ground termi-

nal directly to the chassis of the vehicle. Make sure that all of the paint is sanded or scraped away to

ensure a good ground connection.

*** WARNING ***

Disconnect the negative (-) battery terminal before you start any wiring work! The bat-

tery of your car audio system must be disconnected until the entire wiring installation is

completed.

Your Image Dynamics ampliﬁer requires unrestricted current to deliver peak performance,

so do not “starve” your ampliﬁer by using small power cable. Using under sized power

cable can result in unnecessary over-heating of the ampliﬁer, distortion at high volume

levels and might even cause the thermal protection circuitry to shut-off the ampliﬁer. Re-

member, bigger wire is better!

• Use rubber grommets when running cables through any metal or sharp plastic to

prevent accidental shorting or shearing. Make sure the cables do not interfere with

normal operation of the vehicle.

• The audio signal cables (RCA interconnects) should be kept far away from any poten-

tial sources of electrical interference such as electronic vehicle management systems

(relays, engine computers etc.), wiring harnesses, fuel pumps etc.

Chassis

Ground

(–)

These ampliﬁers are designed to work within a 10 to 16 volt DC range. Before any wires

are connected, the vehicles electrical system should be checked for correct voltage supply

with the help of a voltmeter.

First, check the voltage at the battery with the ignition in the OFF position. The voltmeter

should read no less than 12V. If your vehicles electrical system is not up to these speciﬁca-

tions, we recommend having it checked by an auto electrician before any further instal-

lation. Once the vehicle is checked, make certain the correct cable gauge is used. The SQ

ampliﬁer terminals are capable of accepting up to 4 gauge power and ground cable. We

recommend using as large a gauge cable as possible, use the Power Cable Selection Chart

to calculate the correct power wire size for your application.

POWER WIRING

BAT T+ (Po wer)

This ampliﬁer should be wired directly to the vehicle battery using the appropriate size

cable. Start at the vehicle battery and run the power cable through to the ampliﬁer. Avoid

running the power cable over engine components and near heater cores. The use of an in-

line fuse or circuit breaker is a must; this will prevent the risk of a potential ﬁre caused by a

short in your power cable. Connect the fuse holder or circuit breaker as close to the battery

positive (+) terminal as possible (within 18” from the battery). This fuse or circuit breaker

should be no greater then the sum of the fuses found on the chassis of your ampliﬁer (also

see speciﬁcations chart). You may now connect the cable to the battery, but remember to

leave the fuse out or circuit breaker “off” until all other cable connections are made.

GND (Ground)

When grounding your ampliﬁer, locate a metal area close to the ampliﬁer that is good

source of ground (preferable the ﬂoor pan). Use a short length of cable the same gauge

as your power cable. Once again, investigate the area you wish to use for electrical wires,

vacuum lines, and brake or fuel lines. Use either a wire brush or sandpaper to eliminate

unwanted paint for better contact of the ground.

Secure the ground cable to the body using a bolt, star washer and nut. Spread silicon

over the screw and bare metal to prevent rust and possible water leaks.

NOTE: The Ground must be capable of carrying the same amount of cur-

rent as the positive wire.
