The HornBlasters PA-100H can be installed in many di󰀨erent types of vehicles. The guidelines for the installation
of the product are written so that no matter what vehicle is being used, the installation and operation will be simple
and straight forward.
SELECTING A MOUNTING LOCATION
The following guidelines will help you select a good location.
A) The unit should be mounted on a metal surface to aid heat dissipation. Be sure that this surface is not one that
either generates or is exposed to excessive heat during normal operation of the vehicle.
B) Do not select a location where the unit will be exposed to potential damage from any unsecured or loose
equipment in the vehicle.
C) Be sure the area selected will not allow the unit to be exposed to water.
D) When routing the wires, it is important to choose a path that will keep these wires away from excessive heat and
from any vehicle equipment that could compromise the integrity of the wires (ex. trunk lids, door jams, etc.)
E) When the best mounting location has been determined, securely fasten the unit to its mounting surface using
the supplied hardware.
Caution: As it will be necessary to drill holes into the mounting surface, the installer MUST be sure that no
vehicle components or other vital parts could be damaged by the drilling process. Check both sides of the
mounting surface before drilling begins.
1) Position the unit in its proposed mounting location to ensure that it ts properly. With the unit in place, insert an
awl or other suitable tool into the mounting screw area of the unit and scribe the areas that are to be drilled.
2) Remove the unit from its mounting area and using as appropriately sized drill bit, drill a hole in each of the areas
scribed in the previous step.
3) Return the unit to its mounting location and using the supplied screws, mount the unit onto its mounting surface.
Important
Disconnect the ground (Negative -) terminal from your battery until you are nished making all electrical connections.
WIRING YOUR PA
1. Make sure all connections have a good contact and are secure. Use the provided quick-connect terminals or butt
connectors to make connections between all wires.
2. Make sure you have a good, clean ground. Clean all grime from the grounding location until you have bare metal
or run a wire to the negative terminal on the battery to insure a clean ground.
ACCESSORY SWITCHES
• Your amplier comes with two optional accessory switches that may be used to control other automotive accessories.
These switches are optional to use.
• To power high-amp devices and to reduce risk of damage to your amplier, use these switches each with a relay.
You can use a 4-pin relay to facilitate toggling an accessory on and o, or a 5-pin relay to switch between two
accessories (e.g. between a high pitch air horn and a train horn). To do this, please ow the high-amp diagram on
page 4.
• When wiring the switches, the inputs may be negative or positive. The output will be the same as the input per
switch. (e.g. Attach ‘Accessory 2 Input’ to positive: when the second toggle switch is turned on (I), ‘Accessory 2
Output’ will be a positive; when it is o (0) the output will be dead/not connected).
• In the wiring diagram on the following page, we have marked both inputs as positive for simplicity. In this model,
we would recommend wiring each accessory output to pin 85 on a separate relays. Then wire each relay pin 86 to
ground. You may then use pin 30 as a power source and 87 to connect to your device. On 5-pin relays, pin 97a is
active when your toggle switch is ‘o’ and pin 87 is when the toggle switch is ‘on’.
INSTALLING YOUR PUBLIC ADDRESS SYSTEM
IMPORTANT: We do not oer support on accessory switches and any accessories you attach to the PA
system. Opening the PA control unit will void your warranty with HornBlasters.

• The control harness in the diagram is a representation of the harness at the back of the amplier.
• As shown in the legend, the thick (bolded) lines are ones required to use the public address/siren functions of the unit.
• The thinner lines, marked in the legend as optional connections, may be used to wire up accessories. Please refer to the
‘Accessory Switches’ section in the manual on page 2.
• Although the amplier contains 3 fuses (one for the input power, and one for each of the accessory switches) we recommend
installing an inline fuse from the battery. This will make the connections safer against re and also make maintenance easier.
• If your accessories will draw less than 8 amps each, you may use the diagram above. If your accessories pull more than 8 amps
then follow the wiring diagram on page 4.
• The speaker wires (green) may be reversed. This will reverse the speaker phase and should make no apparent di󰀨erence to
the listener. Ignore the fact that the speaker has red and black wires.

TESTING YOUR INSTALLATION
Before using your public address and siren system, you should test the work you’ve done.
1. Make sure every electrical connection is solid and that there are no loose wires. A loose wire could create an electrical
re, blow a fuse, or cause other havoc in your vehicle.
2. Verify that the speaker and amplier are mounted securely. They must be able to withstand jerks, vibrations, and any
other shock that your vehicle exposes them too. If either does not feel secure, remount it and secure the unit safely before
continuing.
