The first step to installing a new car stereo is connecting the receiver's wiring harness to the adapter harness that will plug into your car. Making long-lasting connections is of the utmost importance. By using one of the methods illustrated below, you can be sure that your connections will last for years to come—and that your new in-dash receiver will work properly.
Method 1: Soldering
Method 2: Posi-Products connectors
Posi-Products™ connectors are easy to attach and stay firmly in place. This is our favorite method because of the quality of the connectors and the simplicity of the technique.
Method 3: Crimping
Crimping can create a reasonably solid connection. You'll need a crimping tool and crimp caps. The only potential drawback: if the caps aren't crimped tight enough, they can shake loose. Give them a good tug before you install that stereo!
Install it like a pro
Facing those two bunches of wires can be intimidating, especially if this is your first installation. But the task really isn't that hard if you take your time and make your connections with care, one wire at a time. Before you know it, you'll have your new stereo installed and ready to rock.
