Having a Public Address system in their cars is something that many car owners want, so that they can play music from their smartphones or car stereos through it. But, not everyone knows how to install one, as it can be a little complicated, and many people are wondering how to connect all the wires and the numerous parts to their cars. However, a few simple tips can help you install a PA system in your car, even if you are not an electronics technician. All you need to do is purchase the necessary supplies, and know how to make some simple wire connections.
1. What Supplies You Need
A typical PA system consists of several parts, including a CB radio, a microphone, an external speaker, an amplifier, and some cables. Additionally, you will need an RCA cable, some duct tape, and a few connectors.
2. Connecting the Components
Once you have gathered all the necessary supplies, you can start connecting the various components to each other.
Hook the CB radio to the amp – this is the first task you have to do. You can connect the CB radio and the amp using an RCA cable, by plugging one end of the cable into the radio’s PA output, and the other into the amp’s RCA plug.
Connect the amp to the speaker – to do this, you just need to plug the speaker wires into the speaker ports of your amp, which is a pretty simple and straightforward task.
Plug in your microphone – if you want to use your PA system to speak through it, you
should get an amp that has a microphone port, and simply plug the microphone’s cable into the amp’s dynamic port.
3. Powering the PA System
This is the tougher part of the installation process. You need to figure out a way to get supply to the amp and to the radio. There are several possible ways to do it, but they all involve connecting the components of your PA system to your car’s battery.
You start by connecting your amp to your battery, which you will need a few cables for. You can buy an amp power kit, which usually includes three wires. Take the red wire and connect the positive port on your amp the the battery’s positive terminal. One end of the black wire goes into the negative port of your amp, and the other end should be attached to some metal section near the engine, that is not painted.
The next step is to connect the amp to a power switch, to be able to turn the amp on and off. Grab a wire and connect one end to the positive port of your amp, and the other end to the port of the switch that’s marked with “in”. Take another wire to connect the “out” port of the switch to a port on your amp that says “remote”.
At first glance, installing a PA system in your car might seem like a daunting process, but if you just follow these step-by-step instructions, you will be able to get it right in no time.
