1. Introduction

1.1 Thanks for purchasing your new

GT series automotive multi-channel

ampliﬁer. Your GT series ampliﬁer will

easily connect to virtually any car audio

system, whether it is factory installed or

purchased separately. The GTQ360 and

GTQ240 include an abundance of unique

features which are described in this man-

ual. The ﬂexible design of their built-in

crossover circuitry allows elaborate sys-

tems to be built more simply than with

conventional components. For optimum

performance, the power ampliﬁer circuit-

ry is a fully-discrete design notable for its

low distortion and unusually clean and

clear sound quality.

In addition to conventional preamp-level

inputs, the GTQ360 and GTQ240 feature

JBL’s Universal Interface™ design, which

facilitates simple connection to factory

radios with the low distortion that is usu-

ally only associated with preamp level

connection. With the Universal Interface

on the GTQ360 and GTQ240, a factory

radio can either be used as the main

music source or simultaneously com-

bined with a CD player or changer that

has volume-control capability. By provid-

ing 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 pres-

ent on the radio’s speaker wires, turning

the ampliﬁer on without an additional

remote wire.

Also, the built-in active cross-over pro-

vides either full-range, high-pass or low-

pass operation. This lets your GT series

ampliﬁer power either subwoofer or com-

ponent speakers in a bi-ampliﬁed system,

or conventional full-range speakers in

simpler systems.

The GTQ360 and GTQ240 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 elec-

tronic crossover.

1.2 About Installation

Although the GTQ360 and GTQ240 are

designed to make installation as easy as

possible, these are extremely sophisticat-

ed products that require proper installa-

tion and setup to realize their full perfor-

mance potential. If you feel you do not

have the necessary knowledge and skills,

we strongly recommend that the installa-

tion be done by your authorized JBL deal-

er.

If you choose to install the GTQ ampliﬁer

yourself, read of the information in thisall

manual you start the installation.before

Pay particular attention to the safety pre-

cautions and notes.

2. Installation and Use

2.1 Refer to the “Speaker-Level Input

Impedance Adjustments” and “Crossover

Frequency Adjustments” sections of this

manual (page 7) to see if you will need to

make alterations to the 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 fea-

tures a code-type security system, make

certain you know the code before discon-

necting the battery!

2. Run a power cable complete with a

fuse (not included) directly from the posi-

tive +12V battery terminal to the desired

ampliﬁer location. Keep the fuse within 6"

of the battery terminal, and position it

before the wire runs through any metal

partition. A minimum of #10AWG is

required for the GTQ240 and #8AWG for

the GTQ360. The GTQ240 requires a 30A

fuse, the GTQ360 a 60A fuse.

Note: All wiring connections should be

made either by soldering with heatshrink

tubing insulation, by using commercially

available high-quality distribution blocks,

or with high-quality crimp-type insulated

connectors installed with a professional-

type, articulated crimping tool. Soldering

crimp-type terminals is recommended for

additional security. Never use wire nuts,

insulation-displacement connectors (i.e.,

ScotchLok type), or twist and tape con-

nections. Do not use electrical tape; it will

loosen with age and extreme

temperatures.

3. Mount ampliﬁer in the desired location

using the included screws.

4. Connect power wiring as shown in the

Wiring Diagram.

5. Connect the outputs from the head unit

to the appropriate inputs of the ampliﬁer

according to the Wiring Diagram with

either (or both) high-quality low-level sig-

nal cables with RCA plugs, or the supplied

speaker-level input connector.

6. Connect the speakers to the ampliﬁer

according to the Wiring Diagram.

7. Turn the gain controls to the

1/4-position for all groups.

8. Set the bass boost of each group to the

desired position.

9. Set the crossover switches for each

group as desired.

10. Set the Group 2 Input as desired.

11. Set the mode switches to Stereo,

Left + Right, or Left Input Only operation

for each group.

12. Double-check your switch settings.

Reconnect the negative battery cable.

Note: Incorrect switch settings can dam-

age your speakers!

13. Turn on the signal source at a low vol-

ume level, and check for the correct out-

put from each speaker.

14. Adjust the ampliﬁer gain controls

using the procedure described in the

“Adjusting the Gain” section.

15. Read the rest of the manual to get

maximum use and enjoyment from your

ampliﬁer.
