PRE-INSTALLATION TIPS
Before beginning your installation, read the following tips on proper
placement of speakers and how to obtain the best sound from the
speakers you have selected.
No. 1:
Always try to have the speakers aimed at the listener. Never install
speakers in a manner that would direct sound toward the floor of the
car. The only exception to not aiming a speaker would be the rear
deck (package shelf behind rear seat). The natural curve of the rear
window, combined with the wide-dispersion tendency of bass sounds,
allows woofers to perform exceptionally well in this location. This is
not true for high-frequency sounds which will be absorbed by the
roof liner long before they reach your ears.
No. 2:
High and mid-frequency sounds are very directional (the higher the
frequency, the more directional it is). This simply means that a tweeter
or mid-range speaker pointing toward the floor (or roof) will only be
clearly heard in the direction at which it is pointed. For this reason, it
is critical that tweeters and mid-range speakers always be installed
so they aim in toward the passenger area and as high in the car as
possible (on top of dash or high up in door panels). Never install
tweeters low in the car.
No. 3:
Select
solid mounting panels! Always make certain the selected
panel is solid and securely attached to the car. Clipped-in plastic
or fire panels make poor mounting surfaces and tend to vibrate
when used. This is far more critical when installing large power pro-
ducing woofers. Mount your speakers securely! If the speaker
has four mounting holes, use all of them.
No. 4:
Woofers need “breathing” room! For a speaker to perform efficiently,
it must move large amounts of air. If you restrict this airflow (try to fit
a large speaker in a small space or if you undercut the recommended
mounting hole size), you won’t have an efficient speaker. Conversely,
the enclosure you mount them in should be somewhat sealed. In
other words, if you mount speakers in door panels, don’t cut any
extra holes in the door.
No. 5:
Tweeters can go in places other speakers can’t. They don’t need
“breathing” room or reinforced mounting panels. All they require is
directional placement. (See tip No. 2.)
No. 6:
Never let any part of the speaker (except the mounting flange) touch
any part of the car. You’ll be amazed what noises a speaker (and
your car) can produce when one touches the other.
No. 7:
Don’t skimp on the quality of the speaker wiring. All Audiovox speak-
ers include wiring rated to properly transmit the normal power load
the speaker is designed for.
