Kia Soul Sound System Upgrade: Boost Your Audio Experience
Kia Soul Sound System Upgrade
The Kia Soul is known for its unique style and fun driving experience. But many owners feel the sound system could be better. If you love music, podcasts, or just want clearer phone calls, upgrading your Kia Soul’s sound system can make a big difference. Whether you drive daily or take long road trips, good audio turns your car into a more enjoyable space.
Upgrading your sound system is not as simple as buying new speakers. There are many choices, and each option affects your budget, sound quality, and installation process. This article explains everything you need to know, step by step, in simple English.
You will learn about parts, costs, installation, mistakes to avoid, and how to choose the right upgrades.
Understanding Your Kia Soul’s Factory Sound System
Before making changes, it’s important to know what you already have.
- Most Kia Soul models come with a basic factory stereo—usually a 6-speaker setup.
- Some trims offer a premium option called the Harman Kardon system (with more speakers and a subwoofer).
- Factory systems have limited power and often lack deep bass or clear highs.
Data Example: The standard Kia Soul audio system outputs around 120 watts total. The Harman Kardon model offers about 315 watts, which is noticeably louder and clearer.
But even premium options can leave audiophiles wanting more. Factory systems are designed to be cost-effective, not high-performance.
Why Upgrade The Kia Soul Sound System?
Upgrading your sound system brings many benefits:
- Clearer sound: Hear voices, instruments, and details better.
- Stronger bass: Enjoy music with more punch and depth.
- Higher volume: Listen louder without distortion.
- More features: Modern upgrades offer Bluetooth, better phone integration, and even smartphone control.
Practical Example: If you stream music from your phone, an upgraded head unit can offer direct Apple CarPlay or Android Auto, making navigation and music easier.
Non-obvious Insight: Many beginners think only speakers matter. But the head unit (radio) and amplifier play a big role in sound quality. Upgrading just the speakers may not deliver the best results.
Choosing Your Upgrade Path
There are three main ways to upgrade your Kia Soul’s audio:
- Speaker upgrade only
- Add amplifier and subwoofer
- Replace head unit (stereo)
- Full system upgrade (all parts)
Each path has pros, cons, and costs.
Speaker Upgrade Only
- Easy install
- Low cost
- Improves clarity and detail
- Limited bass improvement
Add Amplifier And Subwoofer
- Boosts power
- Adds deep bass
- Requires wiring and space for subwoofer
- Higher cost
Replace Head Unit
- Adds features (Bluetooth, USB, apps)
- Improves signal quality
- May require dash kit for Kia Soul
Full System Upgrade
- Best overall sound
- Most expensive
- Requires professional installation
| Upgrade Type | Typical Cost | Skill Needed | Sound Improvement |
|---|---|---|---|
| Speaker Only | $150-$400 | Beginner | Moderate |
| Amplifier/Subwoofer | $200-$700 | Intermediate | High |
| Head Unit | $250-$600 | Intermediate | Moderate |
| Full System | $700-$2,000 | Advanced | Very High |
Selecting The Right Speakers
Speakers are the most common upgrade. But not all speakers are equal.
- Size matters: Kia Soul doors usually fit 6.5-inch speakers. Measure before buying.
- Component vs. coaxial: Component speakers have separate tweeters for better highs. Coaxial are all-in-one and easier to install.
- Sensitivity rating: Higher sensitivity (90+ dB) means better sound with less power.
- Impedance: 4-ohm speakers are standard for most cars.
Example Brands: Popular choices include Pioneer, JBL, Alpine, and Infinity.
Non-obvious Insight: Avoid buying the cheapest speakers. Low-quality speakers can sound worse than factory ones. Spend a little more for a reliable brand.
Adding An Amplifier And Subwoofer
To get powerful bass, you need an amplifier and subwoofer.
- Amplifier: Boosts power to your speakers and subwoofer.
- Subwoofer: Handles low-frequency sounds (bass).
Placement: Subwoofers are often installed in the trunk or under a seat.
Typical specs: For the Kia Soul, a compact 8-10 inch subwoofer fits well. Amplifiers range from 200-600 watts RMS.
Installation Tips:
- Run power wires safely, away from speaker wires to avoid interference.
- Use quality cables for better sound and fewer problems.
Common Mistake: Beginners often forget to fuse the power cable. Always use a fuse near the battery for safety.
| Subwoofer Size | Fits Kia Soul? | Bass Quality |
|---|---|---|
| 8-inch | Yes | Good |
| 10-inch | Yes | Very Good |
| 12-inch | Limited | Excellent |
Upgrading The Head Unit
The head unit (radio or stereo) controls everything. Upgrading adds features and improves signal quality.
Features to look for:
- Touchscreen display
- Bluetooth and USB
- Apple CarPlay/Android Auto
- Equalizer settings
Installation notes:
- You may need a dash kit to fit a new head unit in your Kia Soul.
- Wiring harness adapters make the swap easier.
Real-world Example: Replacing the factory stereo with a Pioneer AVH-3500NEX adds a touchscreen, better sound processing, and smartphone control.
Non-obvious Insight: Some head units have built-in amplifiers. This can improve speaker sound even without a separate amp.
Professional Vs. Diy Installation
You can install upgrades yourself or hire a professional.
DIY Pros:
- Saves money
- Learn new skills
DIY Cons:
- Takes time
- Risk of wiring mistakes
Professional Pros:
- Fast, reliable
- Warranty on work
Professional Cons:
- Higher cost
Data Point: Average labor cost for car audio installation is $60–$120 per hour. Most basic upgrades take 2–4 hours.
Beginner Tip: If you are new to car audio, start with speaker upgrades. They are easiest and safest.
Avoiding Common Mistakes
Many beginners make errors that hurt their upgrade.
- Wrong speaker size: Always check your car’s manual or measure before buying.
- Poor wiring: Bad connections cause noise or failure.
- Skipping fuse: Always fuse the power wire for safety.
- Buying mismatched parts: Make sure all components are compatible (impedance, power handling).
- Ignoring sound deadening: Adding foam or mat to doors reduces vibration and improves sound.
