D6 300.4/600.4
Both pairs of channels on the D6 4-channel amps are capable of being bridged to a
4ÊOhm mono output. Creation of the mono channel is accomplished by using the left
channel positive (+) output connection of the amplifier for the speaker positive and the
right channel negative (-) output connection of the amplifier for the speaker negative.
Note: It is important that a 4 Ohm minimum total speaker impedance load is observed
when bridging the amp! If an impedance load of less than 4 Ohms is used, you will
eventually damage your amplifier and void your warranty.
Bridging
CH 1/2 & 3/4 INPUTS
The RCA cables from your source unit should be inserted here.
AUX. OUTPUT
These RCA outputs are used to provide filtered or unfiltered signals to an outboard
processor or amplifier.

Diamond D6 4-channel amplifiers feature second-order 12dB/octave and fourth-order
24dB/octave Butterworth filters. These filter networks sum to a flat response at their
-3dB break points. This results in a smooth and seamless transition from one frequency
band to the next. Butterworth filters provide maximally flat frequency responses when
compared to other filter structures.
Crossovers
Turn-on (Remote)
Locate the terminal labeled “REMOTE” between the ground and +12V power connection
points on the end of the amplifier. Your source unit should have a wire in its harness
labeled “REMOTE” or “AMP TURN-ON.” Some source units come equipped with a “Power
Antenna” lead only. This should also work. Run this wire from your source unit to the
amplifiers REMOTE connection. Strip approximately 1/2Êinch of insulation from the wire.
Insert the wire into the terminal, and tighten the Allen screw. D6 amplifiers will accept
remote turn-on wire up to 10Êgauge or banana jacks directly.
SPEAKER CONNECTIONS
Diamond Audio recommends using speaker wire of at least 16Êgauge. Lay out the wire in
the vehicle from the individual speaker locations to the amplifier(s). Observe safe wiring
precautions.
D6 Amplifiers will accept speaker wire up to 10Êgauge directly. Locate the speaker
terminal block on the end of the amplifier. Strip approximately 1/2Êinch of insulation
from the wire, insert the wire into the terminal, and tighten the Allen screw. Repeat for all
speaker wires. Please observe recommended minimum speaker impedances to prevent
possible damage.
Banana Jacks can be inserted into the speaker block. Remove the set screw completely
and insert the Banana Jack into the end of the block.
