ELECTRICAL INSTALLATION

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.
1. Follow the wiring diagrams figures 5 and 6 to connect the loudspeaker system to your
automobile radio and possibly to an amplifier. Be very careful of correct polarity of all
connections. (+ to +, - to -)
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.
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.
