Installation Precautions
• Always wear protective eyewear when using tools.
• Check for clearance behind speaker mounting locations before drilling any holes or
installing any screws.
• In some vehicles, verify that the speaker will not interfere in any wires, control
cables, fuel lines or any other factory components.
• For door installation, check for clearance of window crank lever and make sure the
speaker magnet does not hit the window or its mechanism.
• Use a utility knife to remove the excess vinyl, carpet or particleboard before using any
electrical tools to cut out the holes.
• Do not mount speakers where they can get wet.
Installation
Precision Acoustics recommends professional installation of all it’s products. Should you choose to
install this product yourself, please read this manual carefully and refer to the instructions detailed
below. Failure to do so may result in poor product performance, premature or immediate malfunction,
and potential damage to your vehicle or it’s contents.
• Start by unpacking the speakers, and laying out the various components. At this point, discard what won’t
be used for your specific application. For example, the grills will not be used when your vehicle contains
factory provisions that conceal the speaker system.
• Depending on whether you have selected to change the front and/or rear speakers, this will determine
the next steps of your installation. Front speaker will typically be found in the doors, dashboard, or kick
panel locations. Rear speakers are normally found in either the doors, side panels, or rear parcel shelf
locations.
• You want to ensure that the correct replacement size has been purchased, in order to maintain the origi-
nal condition of the vehicle. Choosing a speaker which is larger in size from the original equipment may
require customization in order for a proper installation.
• Next step in the process is removing the factory grills or panels that conceal the speakers. Be careful
when removing any panels, as the clips they use to hold them in place can be quite fragile. Proper tools are
necessary to ensure damage does not result.
• Remove the speakers and set the screws aside. In some instances, these screws are custom machined
and should be reused for your new speakers. Disconnect the wires and/or plugs from these speakers.
• Prior to installing your speakers, it is important to ensure that all obstructions are noted. Window mech-
anisms and truck lid bars are typically near or behind the speaker locations. You want to make sure these
functions will continue to operate without obstruction from the speakers. This would result from larger
magnet structures or deeper speaker than what is provided by the factory.
• It is critical that you determine the polarity of each wire in order to make a proper connection to your
Precision Acoustics speakers. No damage will result from this, but the bass performance will suffer as
result. It is best to test your sound system before installing any grills or panels. If you find that the bass is
stronger when the balance is taken to one side, the wires have in fact been reversed.
• Complete your installation by re-installing all grills or panels, taking note of any wire harness and/or
clips that were disconnected or removed. You are now ready to enjoy the improved sound quality from these
Precision Acoustics speakers.
