My Buying Guides on Spare Tire Sub Box
When I first decided to upgrade my car audio system, I quickly realized that adding a subwoofer was essential for that deep, rich bass I craved. However, space in my vehicle was limited, and I didn’t want a bulky box taking up precious room. That’s when I discovered the spare tire sub box—a clever solution that fits right inside the spare tire well. Here’s everything I learned during my search, which I hope will help you choose the perfect one for your ride.
What Is a Spare Tire Sub Box?
A spare tire sub box is a specially designed enclosure that houses a subwoofer inside the spare tire compartment of a vehicle. Instead of using up cargo space or the backseat area, this box fits snugly into the spare tire well, making it an excellent space-saving option without compromising sound quality.
Why I Chose a Spare Tire Sub Box
I wanted deep bass without losing trunk space or making my car look cluttered. The spare tire sub box offered a clean, factory-like installation and kept my spare tire accessible. It’s perfect for anyone who values both sound performance and practicality.
Key Features I Looked For
- Size and Compatibility: I made sure the sub box matched my vehicle’s spare tire dimensions so it would fit perfectly without modifications.
- Subwoofer Size: Most spare tire sub boxes support 8-inch or 10-inch subs. I chose based on my bass preference and space constraints.
- Material and Build Quality: A sturdy MDF (medium-density fiberboard) construction is common and helps reduce vibrations for cleaner sound.
- Speaker Type: Sealed boxes provide tight bass, while ported boxes offer louder, more booming bass. I personally preferred a sealed box for clarity.
- Power Handling: I checked the RMS power rating to ensure the subwoofer could handle the amplifier’s output without distortion or damage.
- Ease of Installation: Some boxes come pre-wired or with mounting hardware, which made my installation process smoother.
Things to Consider Before Buying
- Spare Tire Accessibility: If you regularly use your spare tire, pick a box that allows easy removal without dismantling the entire setup.
- Sound Preferences: Think about whether you want tight, punchy bass or deep, booming bass, as this affects your choice between sealed or ported enclosures.
- Vehicle Type: Not all spare tire wells are the same size or shape. Measure yours carefully before purchasing.
- Amplifier Compatibility: Make sure your amp’s power and impedance match the subwoofer’s requirements to avoid damage.
- Budget: Prices vary widely, so decide on your budget beforehand but remember that quality often comes at a price.
My Installation Tips
When I installed my spare tire sub box, I made sure to:
- Disconnect the car battery to avoid any electrical issues.
- Run wiring neatly along the car’s frame to keep it hidden and protected.
- Secure the box firmly so it wouldn’t move or rattle while driving.
- Test the system at low volumes first to ensure everything was working properly.
Final Thoughts
Choosing a spare tire sub box was one of the best upgrades I made to my car audio. It gave me great bass without sacrificing space or convenience. If you want an efficient, clean, and effective way to boost your sound system, I highly recommend considering a spare tire sub box. Just take your time measuring, researching, and matching components to your specific needs, and you’ll enjoy fantastic audio for many miles ahead.
