The radio head-unit in your car is a pretty simple piece of equipment. It’s just a convenience for your vehicle—and it’s not even a necessity. However, a good head-unit can enhance your driving experience.
When you’re ready to upgrade your head-unit, you’ll need a wiring harness. A wiring harness isn’t just a piece of wiring. It’s a pre-made set of wires that connects your car’s electrical system to your head-unit. Many head-units don’t come with a wiring harness, so you’ll need to buy that separately.
We’ve researched the best head-unit wiring harnesses to help you find the right one for your vehicle and head-unit.

Best Car Speaker Wiring Harnesses Buying Guide
Before choosing the best car speaker wiring harness you should consider the following options:
1. Car Audio Compatibility: Every car audio system is different, so you need to make sure the speaker wiring harness you choose is compatible with your particular stereo setup.
This usually means having an idea of the size of the wiring harness you’re looking for, whether it’s a “stock” size or a “large” harness. For a stock-sized harness, the wires will be the same size as the stock wiring, so no modifications are necessary.
For a larger harness, you’ll need to make some wiring modifications to your car. This can be done by either running the wires under the dashboard or inside the doors. If you’re not sure what size harness you need, you can consult your car audio installation manual or local car audio shop for guidance.
2. Connectivity: Some speaker wiring harnesses have built-in connections for other audio components in your car such as an amplifier.
This is especially important if you’re planning on installing a subwoofer and amplifier since you’ll need to wire the sub and amp up in series. Some harnesses also have connections for speakers and even the car battery.
3. Sound Quality: The sound quality of speaker wiring harnesses varies. Obviously, the higher the quality, the more expensive the harness is.
You can also expect a higher-quality harness to have a lower tolerance for electrical noise, which is important if you’re planning on hardwiring your speakers.
4. Price: Speaker wiring harnesses vary in price depending on the features they offer. If you’re looking for a harness that’s cheap and just does the bare minimum, you’ll find those for under $10.
On the other hand, you can also find harnesses that offer a ton of features, which will of course cost more. All things considered, a speaker wiring harness shouldn’t cost you more than $30.
5. Durability: The materials and quality of the wiring harness will affect its durability. The higher the quality, the longer your harness will last.
This is especially important if you’re planning on using your harness in a professional setting, like if you’re a car audio shop.
