Installation Instructions
KICKER Impulse Component System woofers are specifically designed for mounting in
freeair applications. While the speakers don’t need a sealed box to work in, for optimum
performance it is important to isolate the sound coming off the front of the driver from
the sound coming off the back of the driver.
This isolation is usually accomplished by using the correct size driver in a factory speaker
location. Grills are included for use in installations that mount the driver in custom loca-
tions.
The tweeter mounts separately to allow the installer to choose the best location for
sound quality and imaging. Two mounting schemes are included to allow more versatility
on tweeter location, plus a coaxial option on the I5.2, I57.2, I6.1 and I6.2.
Mounting:
The easiest mounting location for the woofers is in the front factory speaker locations.
This isn’t always available on all vehicles due to small cutouts or no stock cutout at all. If
custom door-mounting locations are desired for your drivers, be careful to avoid interfer-
ence from window and/or door lock mechanisms. The first step is to find a location on the
door panel that will accept the size of speaker chosen. Now remove the door panel from
the door and check for the operation of the window all the way up and down. Also try to
avoid structural metal and braces if metal must be cut to mount the speakers.
On custom locations that use the supplied grill, mount them as indicated in
this diagram. The I57.2 and I4.2 are not supplied with grills.
The best location for the tweeter is usually high up on the door and as far forward as is
possible without interference from the dashboard. If the chosen place is flat and space
behind the door panel allows the use of the recessed mounting cup, follow the mounting
arrangement in this diagram:
