Specifications

Example 3.
System with a front and a rear system,
and a multimode connected sub.
This system can be used together with most GENE-
SIS 2-channel amplifiers if 12 dB highpass cross-
overs are used to both front and rear systems and
subwoofer. Both front and rear speakers are 2-way
systems. The impedance of the subwoofer is 4 ohms.

Suitable for: DLS and GENESIS 2-channel
amplifiers.
Speaker impedance: 4 ohms for all.
Passive filters:
To the sub: 12 dB lowpassfilter with 300 µF
capacitor + 10 mH coil giving 95 Hz x-over freq.
To front/rear systems: 12 dB highpass filter with
capacitor 200 µF and 6,3 mH coil giving 140 Hz x-
over frequency. The systems original filters must
also be used.
Alternatives: If you use 2 subs they must be of 8
ohm impedance connected in parallel to 4 ohm.
Advantages: One amplifier for the whole system.
Disadvantages: You can´t vary the sound front/rear
or the level to the subwoofer.
Amplifier load: 2 ohm
The
components
inside the
frames must
be added to
the system.
In this example a front and a rear system are
connected in parallel on FRONT. Two or three
subwoofers are connected to REAR. The amplifiers
built-in filters are used. Suitable for Q-100X, Q-200X,
Four Channel and DLS DQ-200.

The mono bridge mode
connected sub should
have an impedance of 4
ohms.
Suitable for: GENESIS and DLS 4-channel
amplifiers
Filter: No passive filters needed. The
amplifiers built-in filters are used.
Built-in filters: Adjust the built-in filters of the
amplifiers according to the owners manual.
The speaker systems own filters are also used.
Alternatives: One or two systems can be
connected in parallel to the FRONT output.
Mid-basses can be connected to the speaker output
of the car stereo through a 12 dB low-pass filter with
550 Hz crossover. C = 50 µF, L = 1,75 mH.
Amplifier load in the FRONT: 2 ohms
example above: REAR: 2 ohms
