INTRODUCTION
Congratulations on your purchase of a NXS speaker system. Your selection of a
NXS Mobile Audio product indicates a true appreciation of fine musical reproduction.
Whether adding to an existing system or including the NXS component speakers in a
new system, you are certain to notice immediate performance benefits.
RECOMMENDATION
A speaker's performance is only as good as it's installation. Proper installation and
mounting location, will maximize the overall performance. We highly recommend
that you have your component speakers installed by an authorized NXS retailer.
However, if you decide to install them yourself, please review the following
installation guide. For up to date product and technical information, please visit our
website at www.nxsmobileaudio.com.
WARNING!
Exposure to high sound pressure levels can cause hearing loss or
damage. Listening to your system at loud levels while driving, will impair
your ability to hear traffic sounds and emergency vehicles. Use common
sense when listening to your system.
TWEETER INSTALLATION
To optimize the tweeter’s mounting location we provide three different mounting
configurations. Determine the best mounting type for your application and follow the

WOOFER INSTALLATION
In most cases the woofer can be mounted in the vehicle’s factory location without the
need to cut a hole in the door panel. However if a alternate location is selected, use
the enclosed speaker template to mark and cutout the holes required for the woofer
and screws. If needed the speed clips provided can be used to secure the mounting
screws.
