It is recommended to connect your amplifier in the following
sequence:
1
Make sure your head-unit is turned off and the volume control
is in its minimum position.
2
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 amp-
lifier! In case of doubt just 'double' a fullrange front or rear pre-out
by using Y-adaptors.
3
Remote lead connection from head-unit to amplifier.
4
Speaker cables to respective speakers or passive crossovers.
Make sure to maintain polarity! "" to "" and "" to "".
For Mono 1-channel mode use of 4/2-channel models, connect the
two terminals "" and "" marked with BRIDGE!
Min. impedance for bridged mode is 4 Ohms!
5
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 sand-papered, i.e. clean from any
paint, rust or dirt for maximum contact.
6
+12 V power connecteonto positive battery pole. Do not
forget to install a main fuse within 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.
