SPEAKER OUTPUTS
The e1800D’s speaker outputs are designed to accept 8 AWG - 16 AWG wire.
The e1800D is designed to deliver power into speaker loads equal to or greater than 2Ω.
To connect the speaker wires to the amplifier, first back out the set screws on the top of the terminal block, using the supplied 2.5 mm hex
wrench. Strip 1/2 inch (12 mm) of insulation from the end of each wire and insert the bare wire into the terminal block, seating it firmly so that no bare wire is exposed. While holding the wire in place, tighten the set screw firmly, taking care not to strip the head of the screw.
! IMPORTANT
Speaker loads below 2Ω nominal are not recommended and may cause the amplifier to initiate a protection mode and shut itself off.
You will notice that there are two “+” positive connections and two
! IMPORTANT
Do not attempt to “bridge” the outputs of this amplifier with the outputs of a second amplifier, including an identical one.

AMPLIFIER STATUS INDICATOR LIGHTS /
PROTECTION CIRCUITRY
There are two status indicator lights on the input / control end of the amplifier:
1)“Power” (Green): lights to indicate that the amplifier is turned on and operating normally.
2)“Protect 1 - Flashing Light” (Red): flashes to indicate that the amplifier’s Level 1 protection circuitry has been activated for one of the following two reasons.
a)The impedance of the speaker(s) connected to the e1800D is less than 2Ω.
b)The vehicle’s charging system voltage has dropped momentarily below 8.2 volts.
3)“Protect 2 - Constant Light” (Red):
illuminates to indicate that the amplifier’s Level 2 protection circuitry has been activated for one of the following two reasons.
a)The amplifier has exceeded its safe operating temperature.This causes the amplifier to reduce power capability in order to protect its circuitry. When the amplifier’s temperature drops to a safe level, the red “Protect” indicator will shut off and the amplifier will return to normal operation.
b)The amplifier protection circuitry has detected a dangerously low charging system voltage (consistantly below 8.2 volts).When the problem is eliminated, the amplifier will return to normal operation.
SERVICINGYOUR 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 the JL AUDIO Technical Department for assistance: (954)
