How to Choose The Best Car Audio Wiring Harnesses for Stereo for You?

To build your own car stereo wiring harness, you will likely have to use an existing harness, or build an entirely new one from scratch, considering your wiring schematics and wire choices. Using a wiring diagram of the car stereo harness provided by Crutchfield, you can map out the wires for each connection on your new stereo wire harness. While it may seem like a kind of colorful macaroni dish, harnesses are what will help connect your new stereo to the wiring in your car.

Many wiring harnesses include connections to connect your new car's stereo outputs directly into your car's factory amp inputs. While steering wheel controller adapters will not help you install a stereo directly, speaker wiring harnesses that we offer to allow you to use factory speaker wiring for your new speakers, much like stereo wiring. If you need to swap out that factory radio you got with the car at some point, the harnesses let you keep your cars factory amps and make it all work properly. This radio wiring harness is not compatible with the factory amplified systems, and it plugs in an aftermarket stereo into the factory radios wiring.

A stereo wiring harness collects and connects the wires (electrical cables) that will carry the electric signal, or power. Simply plug a ground wire into the known good ground, and then test every wire in your cars stereo harness to see if it is continuity. With the power wires marked and out of the way, you can proceed to checking for ground wires. If there is just one wire that has power at any point during this step, that is the power supply wire.

The second style of wiring has wires running out of the load, once again, wires are cut lengthwise and connected at the fuse box. Some kits will have all of the wires connected to a fuse panel, then run the wires out to the end points, cut to length, then connected. Inline fuse panels are designed for mounting under the dash, with all connections made at their terminal points; in some cases, not all the wires will be used. However, take note if you are planning on making your own harness, the RCA connections may be used on the speaker-related wires only, and only if your stereo or car allows that kind of connection.

The best way to ensure your harness will handle higher amps is to use heavier-than-needed gauge wire. Before color codes were introduced in automotive audio, in order to build a harness and properly wire it to other automotive audio equipment, a factory wiring diagram was necessary. If you are replacing wiring in a classic car that has many luxury items, a 24-circuit harness may be needed. So-called oversized wiring is usually a good thing, because it will guarantee that there is a minimum of voltage loss across every circuit, as well as ensure that your harness performs as expected under all conditions (even very hot temperatures).
