Whenever you run wires through sheet metal, use tape or grommets to properly 
insulate the metal edges from cable jackets. This technique prevents chafing 
and possible short circuits that could damage an amplifier or the loudspeakers.

to connect the loud- 

speaker system to your automobile radio and possibly to an ampli- 
fier. 
The tweeters should only be installed through a crossover.

2.

Replace the automobile battery connector and test the loudspeaker 
system.

Caution: Do not apply power to the tweeters without first installing 
crossovers.

ELECTRICAL INSTALLATION

3.

If you plan to use grilles or panels in front of the loudspeaker, ensure 
that sufficient space is available for the path of the loudspeaker  co ne . 
Should the distance not be sufficient, the cone could vibrate 
against the grille or panel thus damaging the loudspeaker.

Installing the Tweeters

Use the enclosed drilling template to cut a suitable hole. Lay the leading 
connector cable and mount the parts as  shown in

Use the enclosed drilling template to cut a suitable hole in the trim 
panel and, if necessary, in the sheet metal behind. Drill holes for the 
fastening screws. Mount the parts as shown in

Attention: If sheet metal must be cut or removed contact your 
authorized car dealer for professional advice. By damage to sup- 
porting body structures the safety certificate may be withdrawn.

Caution: Use care when removing interior trim panels. Car manu- 
facturers use a variety of fastening devices that can be damaged in the 
disassembly process.

Important!

Correct high frequency polarity in the automobile

The correct polarity of tweeter to woofer is a decisive factor for the sound 
quality of the entire sound system.  A false polarity can even "destroy” the 
sound of the best loudspeaker system.  

In some cases a polarity reversal (exchanged positive and negative poles) of 
both tweeters can result in sound quality improvement.  This can result from 
the mounting position, from the distance between loudspeaker and listener 
or also from the sound reflections in the automobile.  Since this is very 
specific, it cannot be decided until the loudspeakers have been mounted in 
the automobile.

Evaluation of the correct high frequency polarity

After the loudspeakers have been mounted in the automobile, they are 
connected with the included crossover. At first the crossover should be 
placed in an easily accessible position, preferably directly reachable from the 
driver's seat.  To recognize the correct polarity as a rule the operation of one 
channel (either left or right) is sufficient.  

The correct polarity of the tweeter can be evaluated most simply from the 
volume.

Adjust the volume control so that the music can be clearly heard in its full 
band width (high, mid and deep range).

Play a segment of music (about 20  30 seconds) and pay close attention to 
the reproduction.  Stop the music and reverse the poles of the tweeter on 
the crossover by exchanging the connecting cables (plus / minus).  Listen to 
the music segment again and try to answer the question which of both 
connections was louder.  Repeat the experiment until you are completely 
sure.  

The louder reproduction shows the correct polarity of the system! 

After the polarity has been decided upon tweeter level adjustment should be 
reconsidered.  

Tips:

* In the dark or with closed eyes the sound differences are usually more 
audible.

* Use a complex instrumental music segment with several acoustic instruments 
for the evaluation.

Should in an exceptional case the available crossover level adjustment still 
not be sufficient (high frequency position at -3dB, with the tweeter still too 
loud), it is permissible to switch in an additional resistor of 2  6 Ohm in 
sequence to the tweeter.
