CAP300F/6=50F Super Capacitor – for Car Audio Systems

Product Information

If you’re passionate about car audio and use high-end equipment like amplifiers, subwoofers, or DSP systems, then you understand how crucial stable voltage is for the entire system. The ideal solution for this need is the CAP300F/6=50F Super Capacitor, a device researched and manufactured in Vietnam, designed to stabilize current and optimize audio performance in custom car sound systems.

With a capacitance of up to 50F, this product functions as an intelligent voltage stabilizer. While most audio manufacturers specify an ideal operating voltage of 14.4V DC, real-world input voltage is often unstable, especially when the vehicle is under load or in motion. CAP300F/6=50F helps maintain a stable voltage ensuring your audio equipment always operates at optimal levels.

This is especially important for bass/subwoofer ranges, which consume a lot of energy. During intense, continuous bass output, if the power supply is insufficient, the system may experience voltage drops or distortion, degrading sound quality. The CAP300F/6=50F Super Capacitor compensates for incoming current fluctuations, effectively resolving energy shortages and delivering a powerful, crystal-clear audio experience.

Key Features

1. Safety Feature – Reverse Discharge Protection
All capacitors and voltage-stabilizing capacitors from Audio Super CAP are equipped with reverse discharge protection. As soon as the car’s electrical system is shut off, the device immediately activates a safety mechanism to prevent excess current from discharging back into the system. This ensures absolute safety when the system is not in use.

This feature is particularly useful in electric vehicles with complex electrical systems, which sometimes require power disconnection to reset. Without this feature, the capacitor may discharge stored energy back into the car, leading to residual voltage and slow drainage. This is dangerous, as it can result in inadequate power supply to the vehicle’s ECUs (control units), increasing the risk of severe malfunctions or even permanent damage to control modules.

2. Initial Auto-Charging – Comprehensive System Protection
All Audio Super CAP models come with initial auto-charging – a critically important and currently world-unique feature. In the event of a power cut or system reset (such as disconnecting the battery), this function prevents power surges when re-connecting, which can otherwise cause blown fuses costing up to 10 million VND. This is a major advantage of the CAP300F/6=50F, offering full protection for both your audio system and your vehicle.

3. Ultra-Fast Current Compensation
Although it doesn’t have voltage step-up or output stabilization like VSS models (Voltage Step-Up Stabilization), this product excels as a dedicated capacitor with extremely fast charge and discharge capabilities. It compensates for input current during sudden power demands, smoothing out the power supply and minimizing voltage drops—supporting system stability and optimized sound quality.

4. Modern LCD Touchscreen Display
Equipped with a 2.4” LCD touchscreen, the device displays critical real-time metrics including:

• Input and output voltage

• Current intensity

• Total system power consumption

• Fuse status and alerts in case of failure or technical issues

This allows users to actively monitor and promptly address any irregularities in the system.

5. Versatile Ports – Full System Support
The CAP300F/6=50F includes 1 input port and 3 output ports, along with 2 dedicated REM/ACC output wires. This allows seamless connection to a variety of audio components, from amplifiers and subwoofers to DSPs. Additionally, the device supports remote control wiring, enabling easy and synchronized control of the entire audio system.
