Electrical Connections

BATT +12V

Connect this terminal with the 12VDC pole of the battery, by using an appropriate power supply wire with a profile of 10 - 20 qmm. Please also install a additional in-line fuse (20 - 40 A) very close to the battery in the power supply wire.

GND

Connect this terminal with the vehicle’s chassis. The ground connection should be as short as possible and should be mounted at a blank metallic point on the chassis. Ensure a stable and safe connection to the Minus-terminal of the battery. The ground wire should have the same profile than the +12V power supply wire.

REM

Connect the remote turn on/off wire of your headunit with the REM- terminal of the soundsystem. This ensures that your Soundsystem turns on and off with your headunit. If your headunit is not equipped with a remote wire, you can also use the power on/off wire of a electrical antenna.

FUSE

The integrated fuse protect your Soundsytem from shorts and overheating. If this fuse is damaged, replace the fuse only with a appropriate fuse with the same rating and construction.

IMPORTANT: Please ensure for all connections the correct polarity. Faulty and interchanged polarity may cause malfunctions and damage.

HFI 200 A-HFI250A specifications

The Hifonics HFI 200 A and HFI 250 A are two powerful yet affordable car amplifiers that bring an impressive audio experience to automotive sound systems. These models are designed for audiophiles seeking high-quality amplification without the burden of a hefty price tag.

The HFI 200 A model delivers an impressive output of 200 watts RMS at 4 ohms and up to 400 watts at 2 ohms, making it capable of powering a wide range of speakers, from coaxial to component systems. On the other hand, the HFI 250 A takes things a step further with 250 watts RMS at 4 ohms and 500 watts at 2 ohms, providing ample power for those who crave deeper bass and greater volume.

One of the standout features of both models is their MOSFET power supply, which promotes efficient energy transfer, ensuring low distortion and high fidelity during operation. The incorporation of a Class AB topology allows for a sound that is both clean and dynamic, making these amplifiers suitable for a variety of music genres, from classical to hip-hop.

Additionally, the Hifonics HFI amplifiers come equipped with adjustable low-pass and high-pass filters, enabling users to fine-tune their audio output to match their listening preferences. The low-pass filter allows for a deeper bass response, ideal for subwoofers, while the high-pass filter prevents distortion on higher frequencies, offering clarity to mid and high-range speakers.

Built with durability in mind, the HFI 200 A and HFI 250 A feature an aluminum heatsink that dissipates heat efficiently, keeping the amplifiers cool during extended use. This is particularly beneficial during long drives or when pushing the amplifier to its limits, ensuring performance remains stable without the risk of overheating.

Furthermore, the amplifiers sport a sleek, modern design with a brushed aluminum finish, making for an aesthetic addition to any vehicle's audio system. With their compact size, these amplifiers can be easily installed in various locations, providing flexibility to car audio enthusiasts.

In summary, the Hifonics HFI 200 A and HFI 250 A amplifiers deliver high-quality sound, power efficiency, and a range of customizable features, making them excellent choices for those looking to enhance their car audio experience.
