【Blam's HQ-0.3F｜Ultra Micro Capacitor for Car Audio】

You want a bit more power in your car audio sound, but it’s difficult to find space to install a large capacitor. In such cases, the Blam's Ultra Micro Capacitor HQ-0.3F is an easy option to consider.

A 300,000μF (0.3F) capacitor that connects to the main battery to support power delivery for your car audio system. It’s consolidated into a capacity that’s practical for individual components—such as a compact power amplifier, CD/navigation head unit, processor, monitor, and more.

Dimensions are 4.3cm × 2.3cm × 6.3cm, with a weight of just 60g. It’s designed to be easier to fit even in limited spaces, without forcing you to make major compromises on installation location. By optimizing the power area, the overall impression of your system may change—for example, improving the sound’s initial attack and stabilizing the low-frequency response.

Also, since it uses a heat-resistant resin case, it supports installation inside the engine bay. That said, the actual effect and the appropriate capacitance can vary depending on your amplifier configuration, power wiring, and how the vehicle is used. If I were choosing, I would consider the entire current system and decide “which device to use it with and how,” rather than choosing based on the product alone.

At LOGON, we don’t just recommend adding a capacitor—we review your current car audio configuration and power setup together, and organize the necessity and installation method. Since it’s a part you’re adding, we want it to be something you can feel fully satisfied with, including the final results and ease of use after installation.
