Precision Power DCX 300.2 - Manual (Page 9)

Note: The cables running from the battery to the rear of the car
should be installed on the side of the car opposite to the antenna.
When using 16 gauge wire or larger, run the speaker wires from the
amplifier location through the vehicle to the speakers. Observe the
same precautions for routing these wires that you followed for
running the power and remote turn on wires. Cut off excess and,
using wire strippers, strip 1/4-inch of insulation. Locate the
speaker/remote turn-on
PowerLock TM connector. Loosen the outer
screws on the underside of the connector. Insert the speaker leads
into the end. Check to be sure you've maintained proper polarity
before securing each wire, and plug the
PowerLock TM into the
amplifier.
