must
be changed. Removing the faceplate and changing the spade connectors
from the ‘4’ setting to the ‘2’ setting accomplish this.
The wiring for the bridged mono mode is as follows:
With the connector end of the amplifier facing you, top side up, the speaker
terminal block is arranged:
LEFT (-); LEFT (+); RIGHT (-); RIGHT (+).
The mono
mode uses the
LEFT (+)
and
RIGHT (-)
connections. An electronic crossover,
such as the
XO3
, should be used to limit the frequency range to the input of the
amplifier for best results.
TWO-OHM CAPABILITY
Unplug the two jumper wires near the four large filter capacitors from the lugs
marked 4 ohm and press them firmly back onto lugs marked 2 ohm. This will
allow the amplifier to operate into a 2-ohm load on each channel, or a 4-ohm load
when used in bridged mono mode (**
see statement above**
). The lugs are
marked 2 for 2-ohm stereo or 4 ohm bridged, and marked 4 for 4-ohm stereo and
8 ohm bridged.
GENERAL TROUBLESHOOTING
NO SOUND
Check all connections. Check main power fuse. Check accessory fuse of your
vehicle. Check to see that +12Vdc is present at the amplifier on the power wire,
and on the red/white remote turn-on wire. Check for a solid ground connection.
Check that the main music source is putting out signal.
BLOWS FUSES
check all connections to be sure no wires are touching each other or the chassis
of the vehicle or any other equipment in your install. Check that your speakers
are in proper working order.
SHUTS OFF
As this amplifier is equipped with thermal and short circuit shut-down electronics,
in the event of high ambient temperature or improper speaker impedances, the
amp will turn itself off. To avoid damage to speakers, turn down the volume while
waiting for the amp to turn itself back on. If this occurs repeatedly, use a fan to
cool the amplifier and check for proper speaker loads and connections.
