Examples for speaker configurations
Two subwoofers with
a single voice coil
One subwoofer with
a dual voice coil
Unique Features of the HELIX M ONE
Smart highlevel input
The latest generation of OE car radios incorpo-
rates sophisticated possibilities of diagnosing the
connected speakers. If a common amplifier will be
hooked up failure messages and loss of specific
features (e.g. fader function) quite often appear -
but not with the M ONE.
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.

In series
Two subwoofers with one voice coil (single voice coil)
or one subwoofer with dual voice coil are connected in
series.
Note: The connection of two voice coils in series will re-
sult in doubling the impedance!
Maximum output power of this configuration:
Two subwoofers with 1 x 2 Ohms correspond to a total
impedance of 4 Ohms: 240 / 480 Watts
One subwoofer with 2 x 2 Ohms also corresponds to a
total impedance of 4 Ohms: 240 / 480 Watts
Two subwoofers with 1 x 1 Ohm correspond to a total
impedance of 2 Ohms: 410 / 820 Watts
One subwoofer with 2 x 1 Ohm also corresponds to a
total impedance of 2 Ohms: 410 / 820 Watts
Note: The connection of subwoofers with 4 Ohms in
series results in a low output power of the amplifier!
Start-Stop capability
The switched power supply of the HELIX M ONE
assures operation even if the battery's voltage
drops down to 6 Volts during engine crank.
