Installation Instructions:
1. Check the contents of the kit to insure that
all parts and components are in the
package. See exploded parts drawing on
front page.
2. Determine the ideal mounting location for
the driver and speaker horn assembly.
Follow diagrams on left.
3. After the location for the speaker driver
has been chosen, use the driver mounting
bracket as a template for making and
drilling the bracket mounting holes.
4. After the driver mounting bracket is
securely mounted to the vehicle, install the
speaker driver to the bracket using ¼” X
20 X ½” hex head cap screws.
5. Install the driver adapter (item 11) to the
speaker driver, making sure to insert the
rubber seal (item 2) and fiber spacer seal
(item 3) between the adapter and driver.
Continue the assembly process in the
sequence shown in the drawing on pg. 1.
6. Install the speaker horn assembly at the
chosen location on the front grill of the
vehicle (fig. 4). Speaker horn assembly
may be secured with the enclosed ty-
wraps (item 10).
7. Route the acoustical flexible tubing from
the driver to the speaker horn assembly
following the warnings to the left. To fit the
acoustical tubing, cut it at the nearest 4”
length (see text at the top of the page).
8. Clamp the flexible acoustical tubing
securely over the speaker horn and driver
adapters with the two hose clamps (item
8). Use ty-wraps (item 10) to secure
acoustical tubing in place (figs. 2 & 3).
IMPORTANT: Due to the lightweight nature of
some plastic front grilles, when mounting the
speaker horn upon it, harmonic vibration
(distortion) of the siren sound is possible. In
this case use a mounting location for the
speaker horn other than the speaker grille
itself. Example: Grille Mounting Posts, Metal
Bumper Flanges, etc.
The standard length of the acoustical flexible tubing is 60”, and is marked every
4” with a white dot. After installing the speaker driver and the speaker horn
assembly in the desired locations, cut the flexible acoustical tubing to fit properly
between these two units in the order as indicated in the drawing on this page. For
optimum sound levels, it is very important to cut the flexible tubing at the 4”
interval markings. example. If 46 inches of flexible tubing is desired, cut the tubing
at either the 44” or 48” length. Acousticle flexible tubing lengths greater than 60
inches are available on special order.
