POWER LED: When lit up, the amplifier is functioning properly.
GAIN CONTROL: Available only on the D1000.4, set based on the head unit's
2
output voltage. Note, this is not a volume control. Always start at the MIN
and slowly increase the gain. Stop as soon as distortion is heard then lower
the gain until the distortion disappear and only clear sound is produced.
RCA INPUT: Low level input of the D1000.4 is 0.2V to 5V RMS while the
3
D1500.2 & D3000.4 is 0.2V to 10V RMS. Be sure to use a HIGH LOW
LEVEL adaptor if the head unit has only speaker output.
4
XOVER SWITCH & FREQUENCY ADJUST: Used to adjust the boosted center
frequency.
BASS BOOST: Available only on the D1000.4, used to add 0 - 12dB to the
5
chosen center frequency.
LINE LEVEL CONTROL: Available only on the D1500.2 & D3000.4 with a
6
range of 0.2V to 10V RMS.
SUBSONIC FILTER: Available only on the D1500.2 & D3000.4, used to protect
7
the speakers from harmful low frequencies and DC Voltage. Note that the
subsonic filter only takes effect when the amplifier is in full range mode.
SIGNAL SENSING SWITCH: Available only on the D1500.2 & D3000.4.

SPEAKER CONNECTION: Each amplifier has bridgeable speaker outputs.
Note that the minimum impedance in bridged mode is 4-Ohm.
11
GROUND TERMINAL: Connect to vehicle's chassis/ground using a short 4
gauge cable (2 feet maximum in length).
12
REMOTE TERMINAL: Connect remote cable to the head unit's remote
terminal. If multiple amplifiers are installed in the same system, additional
relays may be necessary.
13
+12V BATTERY TERMINAL: Connect to battery positive (+) using a 4 gauge
cable.
14
FUSES: Used as an added protection from damaging excessive current. Be
sure to use the proper fuse rating in your installation (see page 12).
PROTECTION LED: Available only on the D1500.2 & D3000.4. When lit up
15
upon powering on, the amplifier may be in self-test mode. If this LED stays
on, shut down the amplifier and locate what may have triggered the amplifier
to protection mode. If problem persists, call or e-mail our technical support
team for further assistance.
NOTE: Be sure to follow the wiring preparations/guidelines as listed on the next
page to ensure proper installation.
