Please read the "Wiring Tips" in this manual on page 26 before
starting with the amplifier connections.
It is recommended to connect your amplifier as follows:
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“ on pages 29 - 32 of this
manual).
Sub pre-outs from head-unit should be fullrange signals because
lowpass pre-out signals always affect the filtering electronics of am-
plifier! 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 keep correct polarity! "
" to "" and "" to "".
For Mono 1-channel mode use the two terminals "" and ""
marked BRIDGE!
Min. impedance for briged 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 chassis contact is well sand-papered, i.e. clean from any paint,
rust or dirt for maximum contact.
In case of problems hook-up your your amplifier directly with the
-12 V negative pole or your battery.
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 minimum. 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.
