installation planning
Proper installation planning is the best way to maximize performance. By planning
your installation carefully you can avoid situations where the performance or
reliability of your system is compromised. Your authorized PrecisionPower

are a valuable resource in helping you with your system design and installation.
amplifier requirements
This speaker system requires a minimum of 45 watts per channel to achieve
reasonable listening volumes in a moving automobile without clipping the amplifier.
PrecisionPower
™
recommends no more than 150 watts per channel as a
maximum so as not to exceed the thermal or mechanical limitations of the speaker
system. Any amplifier between 45 watts and 150 watts may be used. If you choose
to use an amplifier with more than 150 watts use caution as speaker damage may
occur at high volume settings. All PrecisionPower
™
loudspeakers will produce
reasonable volume levels in the automotive environment using moderate amplifier
power. However, the use of a low powered amplifier to try and attain very high
volume levels can lead to overdriving the amplifier and damaging the speaker
system. As a rule, do not turn the volume up above the point where you hear
distortion on musical peaks from either an overdriven amplifier or mechanical
noise from an overstressed speaker. For the best performance and reliability;
select an amplifier with slightly more than the maximum power you are likely to
need to generate the desired volume levels. This margin of reserve power will
ensure that the amplifier will not be routinely driven beyond its design limits.
WARNING: Excessive sound pressure level can permanently damage your
hearing. The maximum volume levels attainable with PrecisionPower
™
speakers,
combined with high-power amplification, may exceed safe levels of extended
listening.
mounting locations
There are many possible choices of mounting locations. The vehicle factory
locations will usually dictate the woofer mounting position. Because of its small
size and multiple mounting options, the tweeter can go virtually anywhere.
PrecisionPower
™
uses an unusually low crossover frequency for the tweeter
which means you are not restricted to mounting the tweeter close to the midrange
speaker. The tweeter can be mounted as far as 24" (60 cm) from the midrange
speaker without causing adverse effects on the sound quality. However, better
results are usually obtained by locating the tweeters and midranges relatively
close to each other, and by keeping the sound path lengths between the listener
and the left and right speakers as equal as possible.
PrecisionPower
™
cannot recommend specific tweeter mounting locations for
each vehicle, but in general try to keep the tweeters as far to the sides of the car
as practical. Avoid placing them above ear level unless the woofers are also above
