either subwoofer or component

speakers in a bi-amplified system,

or conventional full-range speakers

in simpler systems.

The GTS300 and 600 also include

preamp-level outputs which can

provide either full-range, high-pass

or low-pass signal to drive

additional amplifiers. This lets you

build systems of virtually any

design without requiring a

separate electronic crossover.

1.2 About Installation

Although the GTS300 and GTS600

are designed to make installation

as easy as possible, they are

sophisticated products that require

proper installation to realize their

full performance potential.

If you feel you do not have the

necessary knowledge and skills we

strongly recommend that the

installation be done by your

authorized JBL dealer.

If you choose to install the GTS300

or GTS600 yourself read

all

of the

information in this manual

before

you start the installation.

Pay particular attention to the

safety precautions and notes.

2. Installation and Use

Refer to the “Crossover Frequency

Adjustments” and “Speaker Level

Input Impedance Adjustments”

sections of this manual to see if

you will need to make alterations

to their factory settings. If you are

not using the built-in crossover, or

the speaker level inputs, you may

skip this step.

1. Disconnect the negative cable

from the battery.

Note: If the

vehicle’s radio features a code

type security system, make

certain you know the code

1. Introduction

Thanks for purchasing your new

GT series automotive amplifier.

The GT series amplifier you have

chosen includes many unique

features to enhance its perfor-

mance and utility. The power amp-

lifier circuitry is a fully discrete

design notable for its low dis-

tortion and unusually clean and

clear sound quality. Your GT series

amplifier will easily connect to

virtually any car audio system,

whether it is factory installed or

one purchased separately.

In addition to conventional

preamplevel inputs, this model

features JBL’s Universal Interface

design, which facilitates simple

connection to factory radios with

the low distortion that is usually

only associated with preamp level

connection. With Universal Inter-

face, a factory radio can be used

either as the main music source or

combined with a CD player or

changer, which includes volume

control capability, simultaneously

connected to the amplifier. By

providing this two-unit direct

connection, Universal Interface

circuitry eliminates the need for an

FM modulator to interface a CD

player to factory radios, improving

the fidelity of digital playback.

In addition, when using a high-

powered (BTL) radio through the

speaker-level inputs, Common

Sense turn-on circuitry senses the

common-mode voltage present on

the radio’s speaker wires, turning

the amplifier on without an

additional “remote” wire.

Also, the built-in active crossover

provides either full-range, high-

pass or low-pass operation. This

lets your GT series amplifier power

before disconnecting the

battery!

2. Run a minimum AWG #8

power cable complete with a

40 amp fuse (not included) for

the GTS300 or an AWG #6 or

AWG #4 cable with an 80 amp

fuse for the GTS600 directly

from the positive + 12V battery

terminal to the disired

amplifier location. Keep the

fuse to within 6” of the battery

terminal, and before the wire

runs through any metal

partition.

Note: All wiring connections

should be made either by

soldering with heatshrink tubing

insulation or with high quality

crimp type insulated connectors

installed with a professional type,

articulated crimping tool.

Soldering crimptype terminals is

recommended for additional

security. Never use wire-nuts,

insulation-displacement

connectors (i.e. ScotchLok type),

or “twist and tape” connections.

Do not use electrical tape; it will

loosen with age and extreme

temperatures.

3. edMount amplifier in the desir

location using four screws.

4. Connect power wiring as

shown i the Wiring Diagram.

5. om theConnect the outputs fr

head unit to the appropriate

inputs of the amplifier

according to the Wiring

Diagram with either high

quality low-level signal cables

with RCA plugs, with the

supplied speaker-level input

connector, or both.

6. Connect the speakers to the

amplifier according to the

wiring diagram.

7. Turn the input gain adjustment

to the 1/4 position.

8. Set the crossover switches as

desired.

9. Set the input mode switch to

stereo, left + right or right

input only operation.

10. Set the bass boost switch to

the desired position.

11. Reconnect the negative

battery cable.

12. Turn on the signal source at a

low volume level and check

for the correct output from

each speaker.

13. Adjust the amplifier gain

control using the procedure

described in the “Adjusting

the Gain” section.

2.2 Controls and Connectors

1. Preamp-Level Input Connector

–

Use these connectores for line

(preamp) level input to the

amplifier.

2. Preamp-Level Output Connector

– Use these outputs to send the

signal to additional amplifiers.

3. Speaker-Level Input Connector

–

Use this connector for speaker

level input signals. A wire harness

is supplied for use with this

connector. This input also includes

JBL’s Common Sense input

circuitry which turns the amplifier

on as soon as the high powered

head unit connected to this input

is turned on.

4. Speaker Output Connector

–

Connect speaker wiring to this

connector. See “Wiring” directions

for more information.

5., 6., 7., 8., Power Connector

–

Connection for power wires #A.

See “Wiring” directions for

information on proper

connections.
