Make sure your head-unit is turned off and the volume control
is in its minimum position.
RCA outputs of your head-unit to respective RCA inputs of your
amplifier (see „Connecting Diagrams“).
Sub pre-outs from head-unit should be fullrange signals because
lowpass pre-out signals always affect the filtering electronics of
amplifier! In case of doubt just 'double' a fullrange front or rear pre-
out by using Y-adaptors.
Remote leadconnection from head-unit to amplifier.
Speaker cables to respective speakers or passive crossovers.
Make sure to maintain polarity! "A" to "A" and "" to "".
For Mono 1-channel mode use of 4/2-channel models, connect the
two terminals "A" and "" marked with BRIDGE!
Min. impedance for bridged mode is 4 ohms!
Ground connection to chassis ground or -12 V negative battery pole.
If possible keep ground cable as short as possible and make
sure the chassis contact is well sanded, i.e. clean from any paint, rust
or dirt for lowest contact resistance.
+12 V power connection to positive battery pole. Do not for-
get to install a main fuse within 20–30 cm of car battery (fire
hazard)!!!
Do not connect +12 V cable to battery before re-checking every
other connection on the amplifier!
Turn-on your head-unit keeping your volume at the lowest setting.
The green status LED on front of the amplifier heat sink should light
up now. If not, turn-off your head-unit and re-check all wiring to and
from the amplifier for missing or faulty connections.
