Automotive Subwoofer Owner’s Manual W10GTi W12GTi W15GTi

Thank you for choosing a JBL GTi Series

subwoofer. GTi Series 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 general sense,

they don’t show the specific 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.

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.
