POWER LOCK CONNECTORS
Once you have run both the power and ground wires, then connect
the cables to the amplifier. Cut off excess wire, and using wire
strippers, strip the ends of the power and ground cables
approximately 1/4 inch. Locate the
PowerLock TM power and ground
connector (supplied). Using a hex wrench, loosen the screws before
attempting to insert the cable wires. Insert the wires into the
appropriate hole, and tighten the screws. The Power/Ground
PowerLock TM will accommodate 4 gauge wire for these amplifiers.
Note: The amplifier comes with the connector inserted into the
amplifier with the wire clamping screws in the up position as
shown below. Use a 3mm hex head wrench to secure the wires
to the connector. If the connector needs to be unplugged from
the amplifier, use a 2.5mm hex head wrench to remove the two
retaining screws from the connector (set aside and save the
retaining screws).
AMPLIFIER BRIDGING
Pairs of channels in these multi-channel amplifiers are capable of
being bridged into a 4 ohm mono output without switches or bridging
modules. This feature permits the creation of a mono channel for a
