Cable Preparation
Shorten tweeter cable (e.g. AIV Silverado with at least 1 mm²) to the appropriate length and strip both ends. Insert
the red conduit cover (+) over the appropriately marked conductor and the black cover (-) over the remaining
conductor. Solder one end of the stripped conductor to the cable end sleeve. Provide cable end sleeves contacts at
the other end of the cable as well as at the short connection cables of the tweeters.
Note:
Attach tweeter only over the prepared connection cables, preferably with suitable plug contacts.
Soldering of the cables directly to the tweeter is not possible. The tweeter can be severely damaged by
the soldering procedure.
Shorten woofer cable (e.g. AIV Triple Mix with at least 2.5 mm²) to the necessary length to run from the woofer to
the screw connections of the crossover and strip at both ends. Insert the red conduit cover (+) over the appropriately
marked conductor and the black cover (-) over the remaining conductor. Equip both ends of cables with conduit
covers provided and solder cable end sleeves to the one end and the u-shaped metal jackets on the other end..
Note:
If cables with a larger diameter than 2.5 mm² are being used for the installation, they must be provided
with the appropriate u-shaped metal jackets according to DIN 46244. Cables should not be soldered at
the screw connections. The heat from soldering causes the screw connections to move out of position,
making misfires caused by poor contact unavoidable.
In general, the loudspeaker cables should be kept as short as possible and run in such a way that they are kept
separate from the auto’s electrical system, thereby preventing distortion from the generator and electrical wiring.
The loudspeaker cables can also be twisted together to help prevent distortion. Rolling up excess loudspeaker cable
length is not helpful, as it merely increases chances of distortion.
The Crossovers
With all component systems, the tweeter range has been provided with a thermal protection device in the crossover.
This added measure protects the high-quality tweeter against overly high performance levels. However, with
extremely high performance levels, the protecting halogen bulb (12V/20W/G4) can burn out and must then be
replaced with a halogen bulb of the same type. If this happens, remove crossover covers carefully and loosen the
screws on the bulb mounting plate. Replace the defective halogen bulb and firmly tighten screws again.
For audiophiles the halogen bulb can be replaced by a silver wire jumper.
Note:
The overload protection of the tweeter will thereby be lost. Therefore care should be taken in adjusting the
volume control!
Philosophy of the Crossover
Experimentation is highly encouraged!
The crossovers are designed in such a way that a multitude of sound combinations is possible, allowing listeners to
select their personal preference. Because each person hears differently and each vehicle possesses different
acoustics, we can give only basic positioning recommendations here. Therefore, experimentation incorporating
individual preferences is encouraged! Normally high and middle range tones sound louder on the driver’s side,
since the driver sits directly in the sound field of the loudspeakers. The front passenger side is comparatively
quieter, since the speakers are located farther away, with timing delays even being detectable. The result is
inevitably an unbalanced sound.
A basic correction of the sound can be achieved as follows: The crossovers of the front passenger side can be
adjusted through „frequency response“. Note that the frequency of the crossovers on the driver's side is adjusted
until a pleasant, stress-free sound is achieved. Under normal conditions thereafter, high and middle range tones are
