Stereo Amplifier: The JL Audio J2 360.2 is a class A/B stereo
amplifier rated at 110 watts RMS x 2 into a 4Ω load, 135 watts RMS x 2 into
a 3Ω load, and 180 watts RMS x 2 into a 2Ω load. When bridged the output
is 360 watts RMS x 1 into a 4Ω load, 270 watts RMS x 1 into a 6Ω load,
and 220 watts RMS x 1 into an 8Ω load.
Status LEDs: There are two LEDs on the left side of the
- Power: green LED indicates the
amplifier is turned on and operating normally
- Protect: red LED indicates the
amplifier has exceeded its safe operating temperature,
detected a short in a speaker output, or the speaker
impedance is too low
Active Crossover: The crossover can be set to high-pass, low-pass,
or off (full range). The crossover point is continuously variable from 50 Hz to 500 Hz
and the crossover slope is 12 dB/octave.
Bass Boost: The bass boost circuit is adjustable from 0 to +9
dB. The boost frequency is fixed at 45 Hz.
Power and Ground: The Power and Ground connections accept 4
gauge wire, which JL Audio recommends as the minimum size. The set-screw terminals
are tightened/loosened using the included 3mm Allen wrench.
Remote Turn-On: The remote terminal will accept 10 to 18 gauge
wire. The set-screw terminal is tightened/loosened using the included 2mm Allen
Speaker Outputs: The speakers' set-screw terminals will accept
8 to 16 gauge speaker wire; they are tightened/loosened using the included 2.5mm Allen
Preamp Inputs: The amplifier features one set of RCA line level
inputs. The input sensitivity is adjustable from 200mV to 4V RMS.
Speaker Inputs: When connecting the amp to a head unit
without line level outputs, use the included speaker level input harness. In
this case the input sensitivity is adjustable from 2V to 10V RMS.
Preamp Outputs: There is a pair of preamp outputs so you can
send audio to another amplifier in your system. The preamp output is not affected
by the crossover or bass boost circuits.
