Frequently Asked Questions - HFC2000 Hifonics

What is the Hifonics HFC2000 and what does it do?

The Hifonics HFC2000 is a 2.0 Farad power capacitor designed to stabilize the vehicle's electrical system for high-performance car audio amplifiers. It stores energy to supply instantaneous power during bass peaks, reducing voltage drops and improving amplifier efficiency.

How do I install the HFC2000?

Install the capacitor as close to the amplifier as possible. Use the supplied mounting brackets to secure it. Connect the negative terminal to the same ground as the amplifier. Connect the remote wire from the head unit to the Remote terminal. Then charge the capacitor initially as per manual.

Why do I need a power capacitor for my car audio system?

Car audio amplifiers demand high current peaks, especially for bass. Standard car batteries may not keep up, causing voltage fluctuations and distorted sound. A power capacitor provides a reservoir of power to smooth out voltage and improve bass response.

How do I charge the capacitor for the first time?

For initial charge, connect ground, remote, then use the supplied resistor between the capacitor positive and the power wire. Wait about 1 minute until voltage reaches ~10V, then connect directly. The resistor prevents sparks and current surges.

How do I discharge the capacitor safely?

To discharge, disconnect the positive wire, keep ground connected. Bridge the positive and negative terminals with the supplied resistor for several minutes until voltage drops. Audio warning will stop when discharged.

What does the Control-LED indicate?

The Control-LED flashes when voltage fluctuations or drops occur. This indicates a problem with the power supply or connections. Check battery voltage and wiring integrity.

How do I adjust the voltmeter display?

Use a multimeter to measure actual voltage at capacitor terminals. Remove the plexi cover and turn the potentiometer to match the display to the measured voltage.

Can I use multiple capacitors together?

Yes, multiple capacitors can be used. The voltmeter may need adjustment to show consistent readings. Connect them in parallel to increase total capacitance.

What happens if I reverse the polarity?

Reverse polarity triggers an audio warning. Immediately disconnect all connections to avoid explosion or damage.

Is it safe to install myself?

Installation is straightforward for those with basic car audio knowledge, but caution is required due to high currents. If unsure, consult a professional. Always follow safety instructions in the manual.

APPLICATIONS

The power capacitor is used in vehicles for stabilizing the 12 Volt supply and support for car audio amplifiers, if fast and temporary high currents are required. The power capacitor can compensate short-term power peaks on the on-board electrical system for low and powerful bass operations.

The use of the power capacitors results in a considerably improved power expansion of the amplifier.

Car audio amplifiers require very high current peaks for a proper operation. Conventional car battery are not designed to deliver additional power supply to car audio amplifiers.

Another feature of this power capacitor is to filter car AC voltage included by the amplifier power supply. This can cause audible interferences in the audio signal.

SAFETY INSTRUCTIONS

Before you begin with the installation, please attend the following advices in this manual. Otherwise the risk of injury or a damage of the device consists.

The power capacitor is equivalent to common directives to be operated in vehicles inside the European Union and owns a E-mark certification also as a CE-mark.

The capacitor should be installed by qualified and skilled personnel only. Special carefulness is essential, because in case of short circuits hazardous high currents could occur.

The power capacitor stores an extremely large amount of electricity and may explode or cause serious injury. If the device is used for other purposes than originally intended or if not proper used or installed, personal injury or material damage could occur.

The capacitor should be mounted at a mechanically stable position in the vehicle. The device should be fixed properly and professional.

At no time the power capacitor should be exposed to voltages higher than specified or its terminals shorted directly.

Protect the capacitor against humidity and heat (admissible temperature range - 40 °C to +80 °C).

For cleaning use a dry and soft cleaning tissue, by no means any chemicals or water.

WARNING! ELECTRICAL HAZARD

INSTALLATION

For achieving the best results the capacitor should be located close-by the amplifier. The cables between capacitor and amplifier should be short as possible and should have large cross section. While installing the cables or the operation, ensure not to damage the insulation of the cables.

1.) Tightly screw the device with the supplied brackets and screws as close as possible to the amplifier on a mechanically stable position. By no means install the capacitor on any kind of speaker enclosure or on high vibrating positions.
2.) The correct wiring is displayed on the next page. To avoid any interferences, connect the capacitor's ground connection at the same ground terminal like the amplifier.

INITIAL CHARGING PROCESS

For the first initial charging use by any means the supplied resistor, to limit the charge current and to avoid connecting sparks. Connect the “—” ground wire with the “—” terminal of the capacitor. Then connect the remote-wire of the head unit with the remote-terminal on the capacitor.

Then clamp the supplied resistor to the "+" terminal of the capacitor and hold the "+" wire of the battery or distribution block at the other end of the resistor.

The resistor can be disconnected after approx. one minute or if the capacitor reached a load of 10 volts. Then connect the “+” terminal of the battery with the “+” terminal of the capacitor to complete the charging process until 12\~14 volts are achieved.

CAUTION: During the charging process (between 5 \~ 10 Volt) a sound blip is hearable! The resistor may get very hot during the charging process. Please avoid any short circuit on the terminals.

FUNCTIONAL DESCRIPTIONS

Digital Voltmeter

This display indicates the actual operating voltage and is one of the most important features to display the status of the car's power supply.

The voltmeter is working only when a 12 Volt connection on the remote terminal is connected and a voltage of 5 \~ 10 Volts is connected to the power terminals.

During the charging process (5 \~ 10 Volts) or if the voltage falls under 10 Volts a sound blip is hearable.

Control-LED

If major voltage fluctuations or a fall of voltage is occurred, the Control-LED starts flashing. In this case, you need to check on-board power system or the power terminals on faulty connections.

Audio Warning

If a interchange of the poles is occurred, an audio warning is hearable.

In this case all disconnect all connections directly. Danger of Explosion!

Remote

This terminal should be connected with the remote wire of the amplifier or head unit. This prevents, that the vehicle's battery discharge, if the car audio system is not in use.

Potentiometer

This controller allows to adjust the voltmeter. Attend the information on Page 15.

DISCHARGING PROCESS

If the capacitor will be de-installated you need to discharge it completely. To discharge the capacitor, remove the wire at the "+" terminal of the capacitor. Keep the ground terminal "-" connected. Then bridgeover the "-"pole and "+"pole of the capacitor with the supplied resistor.

The discharging process could last some minutes.

To checkup the status, the remote signal (head unit ON) has to be turned on. It is recommended to use a gripper during this procedure, because the resistor may get very hot.

A sound blip is hearable during the discharging a (below 10 Volts) and the Control-LED is flashing.

CAUTION: Never discharge the capacitor without the supplied resistor.

Never discharge the capacitor with bypassing the terminals (short circuit). The capacitor may get damaged or explode.

VOLTMETER ADJUSTMENT

The adjustment is already done by the factory, but can be redone if necessary. By using additional capacitors, various indicated values could be occurred. This can be adjusted by the potentiometer.

Follow these instructions:

1.) Measure the actual operating voltage on the "+" und "-"pole of the capacitor by using an appropriate multimeter.
2.) Remove the plexi-cover of the capacitor and adjust the value with the potetiometer by using a appropriate screwdriver to the same value, you have measured before.
3.) Ensure while removing the cover, not to short the terminals.
4.) Or assign your car audio retailer.
