DC CONNECTIONS
o
D3 amplifiers need proper power and ground connections to deliver maximum
performance and efficiency. Your new amplifier has a regulated power supply. It is
designed to make full power even if the voltage changes. It will draw more current at
lower voltages to make that power. Try to ground your system to a single point in the
vehicle. The gauge of the power and ground cables must be capable of handling the
current needed by the entire system. Power and ground cables must be of the same
gauge. If the alternator is not capable of supplying enough power for both the vehicle
AND the audio system, a high output alternator should be installed for best performance.
Power & Ground (12VDC)
D3 amplifiers are designed to accept up to 4 gauge power and ground spade terminals,
in some systems this may be overkill, but bigger is always better when it comes to power
and ground connections.
Strip approximately 1/4 inch of insulation from the end of the power/ground cable going
to the amplifier. Crimp the proper spade terminal onto the power/ground cable, insert the
terminal into the power block on the end of the amplifier and tighten the screw. Repeat
for each amplifier installed.
Turn-on (REM)
Locate the terminal labeled "REM" on the end of the amplifier. Your source unit should
have a wire in its harness labeled "REMOTE" or "AMP TURN-ON." Run this wire from your
source unit to the amplifiers REM connection. Strip approximately 1/2 inch of insulation
from the wire, crimp a 12 gauge spade terminal onto the wire, insert the terminal into the
power block on the end of the amplifier and tighten the screw.
