Connection
Connect the output of the amplifier with a sufficiently dimensioned speaker cable to the
respective input of the enclosed crossovers.
Connect one tweeter and one woofer to each channel in parallel:
Tweeter left + woofer left -> CH1
Tweeter right + woofer right -> CH2
Please observe the specified polarities and make sure that everything is connected
correctly. All speaker cables must be connected to the signal source (passive crossover
or amplifier output) with the correct polarity, i.e. plus to plus, minus to minus. The playback
quality of speakers connected with reversed polarity is often dramatically poor. A lack of
bass, squawky mids or extremely diffuse sound are the result of unintentionally reversing
the polarity of supply cables.
Attention: If you want to set up the system using DSP and do not use the crossovers
supplied, please note: Even if the electrical phase of the speakers is correct, i.e. according
to the connection diagram, the resulting acoustic phase may deviate from the desired
result depending on the mounting location and tweeter alignment. You should therefore
try out whether reversing the polarity of the cables of BOTH tweeters leads to a more
harmonious sound with more depth.
Cable cross-section
If longer cable runs need to be bridged, e.g. if the power amplifier is located in the trunk,
you should make sure that the speaker cables have a sufficiently high cross-section.
A speaker cable cross-section of 2.5 mm is necessary here; thinner cables will audibly

impair the sound.
TESTING OF THE INSTALLED SYSTEM
Switch on your radio at a very low volume. Slowly increase the volume and listen for
increased distortion or noise. If everything appears to be okay and it just sounds right,
check out the speaker balance of the left and right side by adjusting the balance control
of your head unit. Shifting the balance to the left channel should provide you with sounds
coming solely from the left speaker system, while shifting the balance to the right should
do the same for the right speakers. If anything appears to be wrong, you must recheck the
wiring of the amp, the tweeter or the mid/woofers.
Warning: A mechanical or electrical overload will lead to a defect of the loudspeaker that
is not covered by warranty.
To prevent mechanical overload, the cone excursion of the woofer must not exceed 8 mm
(+/- 4 mm in each direction).
