JBL continually strives to improve its products. New materials, production methods and design refinements are introduced into existing
models without notice as a routine expression of our design philosophy. For this reason, Power Series Multichannel Automotive
Amplifiers may differ in some respects from their published specifications and descriptions, but will always equal or exceed the original
specifications unless otherwise stated.

Figure 4. The JBL Px600.2
amplifier is set to stereo mode
to drive a pair of full-range
speakers.
Figure 5. The JBL Px600.2
amplifier is set to bridged
(mono) mode to drive a single
subwoofer. Use this mode only
when the nominal impedance
of the subwoofer is 4 ohms
or greater.

APPLICATIONS – Px600.2
The JBL Px600.2 amplifier can be
set up for stereo or bridged-mono
operation, as shown in Figures 4 and 5.
NOTE: For simplicity, Figures 4 and 5
do not show power, remote and input
connections.

TROUBLESHOOTING
SYMPTOM LIKELY CAUSE SOLUTION
No audio No voltage at BATT+ Check voltages at
(POWER LED or REM terminals, amplifier terminals
is off) or bad or no ground with VOM
connection
No audio DC voltage on Amplifier may need
(PROTECT LED amplifier output service; see enclosed
flashes every warranty card for
4 sec.) service information
No audio Amplifier is Make sure amplifier
(PROTECT overheated cooling is not blocked
LED is on) at mounting location;
verify speaker-system
impedance is within
specified limits (see
“Specifications” on the
next page)
No audio Voltage less than 9V on Check vehicle
(PROTECT BATT+ connection charging system for
and POWER defective voltage
LEDs flash) regulator
I-E/OPT LED Amplifier is being Check INPUT

Distorted audio Input sensitivity is Check INPUT
not set properly, or LEVEL setting; or
amplifier or source check speaker wires
unit is defective for shorts or grounds
Distorted audio Short circuit in Remove speaker leads
and PROTECT speaker or wire one at a time to locate
