Moreover, the top-mount amplifier controls provide valuable options for customizing sound, such as adjusting the low-pass filter and bass boost.

There are some drawbacks to consider. The subwoofer is not waterproof, which could be a concern for users in wetter climates or who might expose it to moisture. Additionally, while it is designed to fit a wide range of vehicles, compatibility may still depend on specific car models, limiting its universal appeal.
