5) LED off / Amplifier Shuts Off Unexpectedly
The only condition that will shut down
an undamaged M1000/1v2 completely is if
battery voltage or remote turn-on voltage drops
below 10 volts. The "Status LED" will turn off
when this occurs. The amplifier will turn back
on when voltage climbs back above 11 volts.
If this is happening in your system, have your
charging system and power wiring inspected.
For more information on troubleshooting this
amplifier, refer to Appendix D (pages 16, 17).
SERVICING YOUR JL AUDIO AMPLIFIER
If your amplifier fails or malfunctions, please
return it to your authorized JL Audio dealer so
that it may be sent in to JL Audio for service.
There are no user serviceable parts or fuses inside
the amplifier. The unique nature of the circuitry
in the JL Audio amplifiers requires specifically
trained service personnel. Do not attempt
to service the amplifier yourself or through
unauthorized repair facilities. This will not only
void the warranty, but may result in the creation
of more problems within the amplifier.
If you have any questions about the installation or
setup of the amplifier not covered in this manual,
please contact your dealer or technical support.
