What Affects Subs’ Loudness outside the Car?
Understanding what influences the loudness of subwoofers outside the car is pivotal in achieving your desired sound from the system.
Amplifier Class for Sub
The volume and performance of a subwoofer largely depend on its amplifier class, which directly impacts efficiency and power output. Amp classes—such as Class A, B, AB, and D—each offer distinct characteristics that affect sound clarity and intensity. Understanding these differences is key to optimizing your car audio experience. For a detailed breakdown of various amp classes, check out our in-depth guide on the Differences Among Car Amp Classes.
Sensitivity
It indicates how efficiently a subwoofer converts power into sound. A higher sensitivity rating means more sound output for the same amount of power, a crucial aspect when aiming for loudness outside the car. It is about getting the most bang for your buck - literally.
Size
Size matters more than you might think. Larger subwoofers are typically capable of moving more air, resulting in a deeper, more resonant bass that can permeate the barriers of your car with greater ease. However, bigger is not always better. The key is finding a balance that complements your vehicle's acoustics and personal preferences.
Enclosure Type
Sealed enclosures offer tight, accurate bass, while ported enclosures allow for louder, more boisterous bass. Bandpass and passive radiator designs offer unique blends of these qualities. The choice of enclosure directly impacts how sound waves are and affects both the volume and clarity of the bass.
Power Handling
It refers to how much power, in watts, a subwoofer can manage without succumbing to damage. High power handling is a prerequisite for achieving loud sound and bass, but it must be matched with an equally capable amplifier. A well-balanced system in terms of power handling can sustain higher volume levels without distortion.
How to Make Subwoofers Louder Outside the Car?
Achieving that profound loud sound effect outside your car involves more than just increasing the volume. It requires thoughtful tweaks and upgrades like the ones I will discuss below.
1. Correctly Position the Subwoofers
The placement of subwoofers within your vehicle can significantly influence how sound waves escape the confines of your car and fill the air outside. Subwoofers facing towards the rear or a vent can push the bass outside more effectively. You should still experiment with different positions to find the optimal setup that maximizes the outgoing sound’s loudness.
2. Enhance Power
Upgrading your amplifier to a more powerful model can give your subwoofers the energy needed to drive louder sounds and pump the loudness outside the car. However, remember that more power requires better control to avoid distortion, so you should consider a robust amplifier and ensure your subwoofers are designed to handle the increased power. After countless hours of research, I’ve curated a list of the best amplifiers for car subwoofers to help you find the perfect match for your audio needs. Explore the top-rated options and discover the ideal amp to power your subwoofer for deep, high-quality bass.
3. Increase Sub Size
A larger subwoofer typically means a larger surface area for moving air and deeper and more powerful bass. So, increasing the sub’s size can dramatically improve how the bass resonates outside the car.
4. Properly Tune the Sub
This suggestion might sound a bit basic, but going back to the basics can sometimes do the trick. Properly tuning the sub again by adjusting its settings to match your car's acoustics and your personal preferences can make the outgoing sound better and have a stronger presence.
5. Increase Sensitivity
Choosing a subwoofer with a higher sensitivity rating means you'll get more sound output from the same amount of power. It can significantly impact how loud your subwoofer sounds outside the car. When shopping for subwoofers, watch the sensitivity ratings as a key factor in achieving outdoor loudness. Check out my car subwoofer buying guide for essential factors to consider.
6. Use a Ported Box
A ported box, designed with a vent (or port) that allows air and sound waves to pass through, can amplify the bass. It lets lower bass frequencies be emphasized and projected more forcefully and makes the sound more perceptible outside the car.
7. Optimize the Enclosure Compatibility
The synergy between your subwoofer and its enclosure plays a crucial role in sound quality and projection. An optimal match ensures that your subwoofer performs at its best, producing clear, powerful bass that can be heard outside the car. You will need to research to find an enclosure that complements your subwoofer’s design and specifications.
8. Choose the Proper Amp for the Sub
The amplifier powers your subwoofer, and choosing the right one is pivotal for achieving loud, distortion-free sound outside your vehicle.
You should go for one that matches your subwoofer’s power requirements - in terms of wattage and impedance (ohms).
An underpowered amp won't allow your subwoofer to reach its full potential, while an overpowered amp risks damaging the sub. So, you should give utmost priority to finding the right amp that will up the subwoofer’s game for loud sound outside the car.
9. Open the Windows at Times
Sometimes, the simplest methods are the most effective. Opening the windows, even slightly, can allow the bass to escape the vehicle more freely and improve the subwoofer's external loudness.
It works well when stationary or driving at low speeds. It is a quick and easy way to boost your system’s outside presence without requiring technical adjustments.
10. Use External Batteries or Capacitors
Using external batteries or capacitors provides an additional power source. It ensures your audio system has the energy to perform at high levels without affecting your vehicle's performance.
Capacitors are particularly useful for managing the power demands during peak bass notes. On the other hand, batteries make sure there is a steady power supply for consistent performance.
The Final Verdict
Getting your subwoofers to sound louder outside the car means you've got a bunch of tricks up your sleeve. This whole process of how to make subs louder outside the car isn't just about enjoying great sound; it also shows how much you're into your car's audio system.
All I can tell you is to have patience, as a bit of trial and error and being open to learning and tweaking things along the way can do the magic for you.
