THANK YOU

for choosing a JBL®GTi Series subwoofer.

GTi subwoofers are designed to

provide maximum sound output in a

variety of enclosure types while

maintaining the superb sound quality

associated with JBL. To ensure the best

subwoofer performance, we strongly

recommend that installation be entrusted to a

qualiﬁed professional. Although these instructions

explain how to install a GTi Series subwoofer in

a cgeneral sense, they don’t show the speciﬁ

installation procedures that may be required for

your particular vehicle. If you feel you don’t have

the necessary tools or experience, don’t attempt

the installation yourself; rather, ask your authorized

JBL dealer about professional-installation options.

INSTALLATION WARNINGS AND TIPS

WARNING

Playing loud music in an automobile can

hinder your ability to hear trafﬁc, as well

as permanently damage your hearing.

We recommend listening at low levels

while driving. JBL accepts no liability for

hearing loss, bodily injury or property

damage resulting from use or misuse of

this product.

YOUR CAR AND BASS

REPRODUCTION

Depending on the size of the vehicle’s

interior listening space, reproduced

frequencies below 80Hz may be boosted

by nearly 12dB per octave as frequency

decreases. This effect, commonly known

as transfer function, or cabin gain, plays

an important role in deﬁning the in-car

frequency response of your subwoofer.

It is displayed graphically, along with

freespace response, on the enclosed

data sheet for your GTi subwoofer.

POWER-HANDLING

LIMITATIONS

The power-handling capacity of any

subwoofer is related to the excursion

limit of its suspension and its ability to

dissipate heat. A speaker reaches its

excursion-limited power-handling

capacity when its suspension is

stretched to its limit. The excursion

curve shown on the Enclosure Design

Sheet (included with your woofer)

displays cone excursion at the input

power level required to drive the woofer

to maximum linear excursion (Xmax).

The input power shown may be used

as instantaneous input only.

Thermal power handling is determined

by the amount of heat that may be

dissipated by the driver’s voice coil.

The power-handling rating assigned

to your GTi Series subwoofer is its

thermal-power-handling rating. This

rating assumes a clean (unclipped)

signal. A clipped waveform has much

higher average power, due to the longer

duty cycle at the top and bottom of the

waveform; it will heat the woofer’s voice

coil faster than a clean signal and may

damage the voice coil. A square wave

has a 100% duty cycle and is extremely

dangerous for any speaker. Audible

distortion in the output of your woofer

is an indication that your ampliﬁer may

be clipping, which could damage your

speakers over time.
