Your KS coaxials were specially designed for “Livin’ Loud” out in the harsh automotive
environment. They are made of advanced materials and construction techniques to
maintain optimal performance for years to come.
Application
The Kicker KS coaxial speakers are specifically designed for mounting in free-air
applications. The speakers do not require a sealed enclosure for optimum performance.
It is important to isolate the sound coming off the front of the driver from the sound
radiating from the back of the driver. This isolation is usually accomplished by using the
driver in a factory speaker location, or in a location with a semi-isolated rear chamber.
See Figure 1.
Location
The sound produced by the KS coaxials is directional. Find the best location for
stereophonic sound. If necessary, add more KS coaxial speakers to the system to help
distribute and balance the sound. After determining the best mounting locations, carefully
check the areas where the mounting hardware will be placed. See Figure 2.

Mounting
If you are replacing factory speakers in their original locations, you may have to enlarge the
speaker cut-outs and pre-drill new screw holes using a 7/64” (2.5mm) bit. Custom mounting
locations will require more preparation and work. In either case, make sure the speaker will
not interfere with the trunk and door opening and closing mechanisms, and the enclosed
screws will not puncture the fuel tank, wiring, or interfere with any other mechanical parts on
the underside of the mounting surface. Cycle the windows all the way down and up.
If the speaker cut-out locations require you to cut metal, avoid structural metal and braces.
If the door body and panel cannot support the weight of the speaker, an optional reinforcing
ring (thin piece of wood or Medium Density Fiberboard) may be fastened or adhered to the
door body. Mount the speaker to the vehicle as outlined in Figure 2.
If factory speaker wiring is not available in your desired location, it may be necessary to run
speaker wire through the door jamb. The speaker wire should be kept away from sharp
edges and avoid the possibility of getting pinched by the door. An existing grommet in the
door jamb is the ideal place to run the
speaker wire. If the factory hole and
grommet do not exist or are inaccessible,
you must drill a hole to run the speaker
wire through the door jam. Be careful not
to drill into other wiring or door
mechanisms. Any time a wire is run
through a hole, it is necessary to insert a
rubber or plastic grommet to protect the
wire from damage as outlined in Figure 3.
If the supplied hardware is not applicable
to your installation, some other means of
securely attaching the speakers to the
vehicle must be used.
