If you’re looking to add a little extra functionality to your car, a CB radio is a great option. But if you’re not familiar with how to wire one up, don’t worry—this guide will teach you everything you need to know. First, find an appropriate CB radio. There are many different models available on the market, so it’s important to choose one that fits your needs. Some radios require an external antenna, while others come with one built in. Once you’ve chosen your CB radio, it’s time to connect it to your car battery. To do this, locate the battery terminals and connect the black (negative) terminal of the CB radio to the negative terminal of the battery, and connect the red (positive) terminal of the CB radio to the positive terminal of the battery. Make sure that both terminals are fully connected before continuing. Next, locate and connect the antennae cables from your CB radio to either an outside antenna or inside antenna port on your car. If you’re using an outside antenna, make sure that it’s properly mounted and secure before connecting it to the CB radio. Once everything is connected, turn on your CB radio and test it out! ..
