What is AdPower Sonic for Car Audio?

AdPower is a series of products designed to improve the airflow of car and motorcycle engines. Building on the static electricity removal technology developed for vehicle products, AdPower Sonic was created as a specialized product for audio systems. Developed under the supervision of Koji Morimoto, Chief Recording Engineer at avex, AdPower Sonic for car audio has received high praise from numerous composers and professional musicians.

Designed to withstand the high heat, humidity, and vibrations typical of in-car environments, it features a specially formulated adhesive that ensures secure attachment to a variety of speaker materials.

Simply apply it to your speakers and enjoy a higher level of sound quality—effortlessly, even in your car.

Who This Is For

This may not be for you if:

This product is designed for fine-tuning subtle aspects of sound, such as clarity, definition and spatial imaging. The perceived effect may vary depending on your environment, equipment, and personal sensitivity. If you are expecting a drastic transformation, this product may not meet your expectations.

Why Does the Sound Quality Change?

According to sound analysis conducted by the National Institute of Advanced Industrial Science and Through sound source analysis conducted at the National Institute of Advanced Industrial Science and Technology (AIST), it was found that attaching AdPower Sonic to speakers tends to increase the Interaural Cross-Correlation (IACC).

IACC (Inter Aural Correlation Coefficient): A metric used to represent the spread or diffusion of sound.

In addition, an analysis of reverberation indices carried out at the Acoustics and Signal Processing Labs, College of Information Science & Engineering, Ritsumeikan University, showed that in the low-frequency range (250–500 Hz), the reverberation tends to last longer, while at the lowest frequency of 125 Hz, it tends to become shorter.

These results suggest that, in actual auditory perception, listeners may experience impressions such as “tighter bass” and “clearer sound localization and definition.” ※

Customer Reviews

The treble became smooth and pleasant, and the bass was much cleaner and more open.
The effect was immediate. I placed it on my car speakers as shown in the site’s photos, and the sound became noticeably clearer.
I compared it with the songs I usually listen to, and the vocals became clearer, making it feel like the volume had increased.
The bass tightened up, and the treble became clearer. Honestly, I was skeptical at first, but I’m very satisfied. The reasonable price is also a plus.

Typical In-Car Speaker Layout

We generally recommend the rectangular type for door speakers, and the hexagonal type for tweeters and small speakers. Since speaker sizes vary depending on the vehicle model, we suggest using the rectangular type for speakers with a diameter of 10 cm (4 inches) or larger, and the hexagonal type for those smaller than that as a general guideline.

It refers to the diameter of the opening inside the speaker grille (mesh area). Please use this as a reference when selecting the product.

You can adjust the effect by changing the size or number of sheets applied. If you would like to enhance the effect, we recommend adding more sheets.
