About This Manual

To attain maximum amplifier perfor-

mance, we encourage you to read the

remaining pages before installing and

operating your new JBL Power Series

amplifier. Especially review the

Applications section for ideas on design-

ing and expanding your system. Also,

save these instructions for future refer-

ence. Installation of automo-Important:

tive stereo components can require

extensive experience in performing a

variety of electrical and mechanical pro-

cedures. Although these instructions

explain how to install a JBL Power Series

amplifier in a general sense, they do not

show the exact installation methods for

your particular vehicle. If you do not

have the experience necessary, do not

attempt the installation yourself; instead

ask your Authorized JBL Car-Audio Dealer

about professional installation options.

Installation Precautions and Notes

• The JBL P-4020 (or P-4040) has five

levels of circuit protection that monitor

the amplifier and will shut it down if

the electrical system voltage drops

below 5Vdc or exceeds 18Vdc, temper-

atures are above 194° F (90° C), short

circuits occur, or current draw exceeds

product specifications. For best perfor-

mance, check the intended mounting

site to make sure the operating envi-

ronment does not create conditions

that will trigger the protection circuit.

• Prior to installation, turn off all audio

systems and other electrical devices.

Also disconnect the (–) negative lead

from the vehicle’s battery.

• At the installation site, locate and make

a note of all fuel lines, hydraulic brake

lines and electrical wiring. Use extreme

caution when cutting or drilling in and

around these areas.

• Check clearances on both sides of a

planned mounting surface before

drilling any holes or installing any

screws. Remember that mounting

screws can extend behind the mount-

ing surface.

Thank you for purchasing your new

JBL Power Series™ amplifier. Power

Series amplifiers feature the latest

advances in discrete-circuit topology,

ensuring low distortion and superbly

clean and clear sound quality. In addition

to RCA-type pre-amp inputs, Power

Series amplifiers feature Universal

Interface™, designed to facilitate integra-

tion with factory-installed audio systems

for distortion-free performance that rivals

conventional pre-amp connections.

Included in the Universal Interface circuit

is Common Sense™ turn-on. Common

Sense turn-on senses the common-mode

voltage present on the speaker outputs of

factory and aftermarket radios, turning on

the amplifier without a separate remote

wire. All Power Series amplifiers feature

built-in electronic crossovers and pre-amp

outputs for easy system expansion with-

out requiring outboard processors.

• Always wear protective eyewear when

using tools.

• When routing cables, keep input signal

cables away from power cables and

speaker wires.

• When making connections, make sure

that each connection is clean, insulated

and properly secured. Observe the

polarity markings on the rear panel.

Refer to the application drawings to set

up the amplifier for operation in stereo,

bridged-mono, bi-amp or tri-mode con-

figurations.

• If the amplifier’s fuse must be replaced,

use only the same rating and type as a

replacement. Do not substitute another

kind.

Controls and Connectors

1. Pre-amp Level Input Connector –

Connects to line-level output from the

source unit.

2. Universal Interface Speaker-Level

Connector – Connects to speaker-level

output from the source unit. Provides

Common Sense amplifier turn-on

when used with factory radios

(2-channel on P-4020, 4-channel on

P-4040).

3. Pre-amp Level Output Connector –

Connects to other amps or processors

in the signal chain (flat on P-4020, flat

or filtered on P-4040).

4. Speaker-Output Connector – (2-chan-

nel on P-4020, 4-channel on P-4040).

5. Fuses – P-4020: 20A ATC type, P-4040:

30A ATC type.

6. Power Connector – Connection for

12V +, Gnd and Rem.

7. Input-Mode Switch – Sums left and

right inputs.

8. Input-Sensitivity Control – Adjusts

input sensitivity for pre-amp level and

speaker-level inputs.

9. Pre-amp Output Selector Switch –

Selects input path for pre-amp output.

Output can be summed from front and

rear inputs with no filter, or filtered by

the front or rear crossover.

10. Rear-Channel Input Selector – Selects

rear-channel input between front input

and rear input.

11. Crossover Selector – Determines

whether the crossover is a High-Pass

filter (HP), a Low-Pass filter (LP) or

unfiltered (Flat).
