Speaker Wiring; Speaker/Remote Powerlock - Precision Power PowerClass PC4200 Owner's Manual

SPEAKER WIRING

Using 16 gauge 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 connector. Loosen the
four outer screws on the underside of the connector and insert
the front ( PC4200, PC4400 and PC4800 ) or sub ( PC6600 )
speaker leads into the end. Check to be sure you've maintained
proper polarity before securing each wire.

Speaker/Remote PowerLock

For the rear channels, locate the four terminal speaker
PowerLock connector. (For PC650, the front channel also uses
a four terminal PowerLock connector.) On 4 and 6 channel
PowerClass Amplifiers, all speaker PowerLocks plug into the
amplifier with the screws facing up. Loosen the screws on the
top of the blocks and insert the stripped ends of the speaker
wires into the end. Double check polarity, secure each wire by
tightening the screws, and plug the PowerLock connector into
the amplifier with the screws on top.
