Convertible Car Audio Upgrades: Reviews and Recommendations

Convertible cars are a symbol of freedom and luxury, allowing drivers to enjoy the open road while feeling the wind in their hair. However, one aspect that can often be lacking in these vehicles is the audio system. Due to the unique design of convertibles, the audio quality can be compromised, making it difficult to enjoy music or have clear conversations while driving. Fortunately, there are several audio upgrades available that can significantly enhance the audio experience in a convertible car. In this article, we will explore some of the best convertible car audio upgrades, providing reviews and recommendations based on extensive research and expert opinions.

1. Upgrading the Speakers

The first and most crucial step in improving the audio quality in a convertible car is upgrading the speakers. Convertibles often suffer from poor sound reproduction due to the lack of an enclosed cabin, which can result in sound distortion and reduced bass response. By replacing the factory-installed speakers with high-quality aftermarket options, drivers can enjoy clearer and more balanced sound.

When choosing speakers for a convertible car, it is essential to consider their power handling capabilities, sensitivity, and frequency response. Power handling determines how much power the speakers can handle without distorting the sound, while sensitivity indicates how efficiently the speakers convert power into sound. A higher sensitivity rating is preferable for convertibles, as it allows the speakers to produce louder sound even with lower power inputs. Additionally, a wide frequency response ensures that the speakers can reproduce a broad range of audio frequencies accurately.

Some popular speaker options for convertible cars include:

  • Bose SoundLink Revolve+
  • JBL GTO609C
  • Rockford Fosgate R165X3
  • Pioneer TS-A1670F

These speakers offer excellent sound quality, durability, and compatibility with convertible car audio systems. They are designed to withstand the challenges of open-air driving and provide a more immersive audio experience.

2. Adding a Subwoofer

While upgrading the speakers can significantly improve the overall audio quality in a convertible car, adding a subwoofer takes the listening experience to a whole new level. Subwoofers are specialized speakers that reproduce low-frequency sounds, such as deep bass notes, with greater accuracy and impact. In a convertible car, where bass response is often compromised, a subwoofer can make a noticeable difference.

When selecting a subwoofer for a convertible car, it is crucial to consider its size, power handling, and enclosure type. The size of the subwoofer determines its ability to produce low-frequency sounds, with larger subwoofers generally delivering deeper bass. Power handling should match the amplifier’s capabilities to ensure optimal performance, while the enclosure type affects the subwoofer’s sound output and installation requirements.

Some popular subwoofer options for convertible cars include:

  • JL Audio 10TW3-D4
  • Alpine Type-R SWR-12D4
  • Kicker CompRT 43CWRT102
  • Rockford Fosgate P300-12

These subwoofers offer powerful bass reproduction, compact designs, and easy installation options, making them ideal for convertible car audio upgrades.

3. Installing an Amplifier

While upgrading the speakers and adding a subwoofer can significantly enhance the audio quality in a convertible car, installing an amplifier is essential to ensure that the upgraded components receive sufficient power for optimal performance. An amplifier increases the power output of the audio system, allowing the speakers and subwoofer to produce louder and clearer sound.

When choosing an amplifier for a convertible car, it is important to consider its power output, number of channels, and compatibility with the existing audio system. The power output should match the power requirements of the speakers and subwoofer, ensuring that they can operate at their full potential. The number of channels determines how many speakers and subwoofers the amplifier can support, with multi-channel amplifiers being suitable for more complex audio setups.

Some popular amplifier options for convertible cars include:

  • Alpine MRV-F300
  • JL Audio JX1000/1D
  • Rockford Fosgate R500X1D
  • Kicker CXA800.1

These amplifiers offer high power output, compact designs, and advanced features such as built-in crossovers and equalizers, allowing drivers to fine-tune their audio system for optimal performance.

4. Sound Deadening and Insulation

In a convertible car, external noise can significantly impact the audio quality, making it difficult to enjoy music or have clear conversations. To mitigate this issue, sound deadening and insulation materials can be installed to reduce external noise and improve the overall acoustic environment inside the car.

Sound deadening materials, such as mass-loaded vinyl (MLV) and butyl rubber sheets, are applied to the car’s interior panels to absorb and block external noise. These materials help reduce vibrations and resonance, resulting in clearer sound reproduction. Additionally, insulation materials, such as closed-cell foam and acoustic carpet padding, can be installed to further enhance the sound quality by reducing road and wind noise.

Some popular sound deadening and insulation options for convertible cars include:

  • Dynamat Xtreme
  • Noico Solutions Sound Deadening Mat
  • Second Skin Damplifier Pro
  • Stinger Roadkill

These materials are easy to install and provide significant improvements in sound quality and comfort, making them essential for convertible car audio upgrades.

5. Optimizing the Audio System

Once the speakers, subwoofer, amplifier, and sound deadening materials have been installed, it is important to optimize the audio system for the best possible performance. This involves adjusting various settings and configurations to ensure that the audio system delivers accurate and balanced sound.

Some key steps in optimizing the audio system include:

  • Setting the gain levels of the amplifier to match the input signal and prevent distortion.
  • Adjusting the equalizer settings to fine-tune the frequency response and compensate for any audio deficiencies.
  • Positioning the speakers and subwoofer correctly to achieve the best soundstage and imaging.
  • Calibrating the time alignment to synchronize the arrival of sound from different speakers, improving the overall sound quality.

Optimizing the audio system may require professional assistance or the use of specialized tools and software. It is recommended to consult with an experienced car audio installer or refer to the user manuals of the audio components for detailed instructions.


Convertible car audio upgrades can significantly enhance the audio quality and overall listening experience in these vehicles. By upgrading the speakers, adding a subwoofer, installing an amplifier, and incorporating sound deadening and insulation materials, drivers can enjoy clearer and more immersive sound while driving with the top down. Optimizing the audio system through proper configuration and calibration further ensures that the upgraded components perform at their full potential.

When considering convertible car audio upgrades, it is important to choose high-quality components that are specifically designed for open-air driving conditions. Additionally, professional installation and optimization may be necessary to achieve the best results. By following these recommendations and conducting thorough research, drivers can transform their convertible cars into audio havens on wheels.
