5. Connecting the remote input
The remote input (REM) has to be connected
to the radio remote output if the ampliers low-
level line inputs are used as signal inputs. We
do not recommend controlling the remote input
via the ignition switch to avoid pop noise during
turn on/o.
If the Highlevel Input is used this input does not
need to be connected as long as the car radio
has BTL output stages.
6. Connecting the loudspeaker outputs
The loudspeaker outputs can be connected
directly to the wires of the loudspeakers.
Never connect any of the loudspeaker cables
to the chassis ground as this will damage your
amplier and your speakers.
If The positive terminal is indicated on most
speakers. The minimum load impedance must
not be lower than 1 Ohm, (2 Ohm in TwinPow-
er Link operation) otherwise the amplier pro-
tection will be activated. Examples for speaker
congurations can be found on page 20 et sqq.

Smart highlevel input
The latest generation of OE car radios incorpo-
rates sophisticated possibilities of diagnosing the
connected speakers. If a common amplier will be
hooked up failure messages and loss of specic
features (e.g. fader function) quite often appear –
but not with the M ONE X.
The new ADEP circuit (Advanced Diagnostics Error
Protection) avoids all these problems without load-
ing the speaker outputs of the OE radio during high
volumes unnecessarily.
Start-Stop capability
The switched power supply of the HELIX M ONE X
assures operation even if the battery’s voltage
drops down to 6 Volts during engine crank.
