SPEAKER OUTPUTS
The JX360/2’s speaker outputs are designed to
accept 16 AWG - 8 AWG wire.

Bridged
JX360/2 is designed to deliver power into
speaker loads equal to or greater than 2 ohms per
channel when using a “stereo” configuration and
speaker loads equal to or greater than 4 ohms
when using a “bridged” configuration.

Speaker loads below 2 ohms nominal per
channel are not recommended and may cause
the amplifier to initiate a protection mode.
BRIDGING CONSIDERATIONS
Bridging is the practice of combining the
output of two amplifier channels to drive a single
load. When bridged, each channel produces
signals of equal magnitude, but opposite polarity.
The combined output of the two channels
provides twice the output voltage available from
a single channel. The JX360/2 has been designed
for bridging of its channels without the need for
input inversion adaptors.
To bridge a pair of channels, use the
“
Left +
” and
“
Right –
”
speaker connectors only
(the “
Left –
”
and
“
Right +
”
remain unused).
When bridged, the amplifier will deliver
optimum power into a 4 ohm load.

When bridged, the JX360/2
will deliver 360W x 1 into a 4 ohm load or
220W x 1 into an 8 ohm load. Operating a
pair of bridged channels into a load lower
than 4 ohms is not recommended.

Any bridged channel pair must be fed by both
Input Channels corresponding to it (Left and
Right). Failure to do so will result in significant
audible distortion.
When the JX360/2 is operating in bridged
mode, the output will be in mono (only one
channel). This mono channel can contain right
channel only information, left channel only
information or the sum of the information from
both the right and left channels. In order to
achieve one of these options, configure the inputs
to that pair of channels in one of these two ways:
1) Left Channel Only or Right Channel Only
Information:
If you wish to send a left-only
or right-only signal to the JX360/2, use a
“Y-Adaptor” to split the single channel signal
into both left and right RCA inputs. This
option is useful when using the JX360/2 to
drive left channel speakers only and another
JX360/2 to drive right channel speakers only.
2) Left + Right Channel Information:
When bridged and fed by a stereo input, the
JX360/2 will automatically combine the left
and right input channels into a summed mono

system or a summed mono center channel.
