Trouble Shooting

Malfunction: no function

1. The power connections are faulty or defected.

2. The wires have no electrical or mechanical contact.

3. The fuse is damaged. Observe the correct fuse rating when you replace the fuse .

Malfunction: no sound signal

1. The RCA wires are faulty connected or defected.

2. The loudspeaker is damaged.

Malfunction: Distorted signal

1. The loudspeaker is overloaded.

a. Reduce the level, until the sound quality is good.

b. Reduce the bass level in your headunit, until the sound quality is good. c. Turn off the loudness-mode or the bass-qualizer in your headunit.

Malfunction: Hiss and white noise

1. The Level controller is turned to the maximum level. Reduce the level.

2. The Bass Boost Controller is tuned to the maximum level. Reduce the Bass Boost.

3. The hiss is provided by the headunit. Ensure this, by removing the line-in signals. Then turn the Soundsystem on. If the hiss is not hearable anymore, your headunit causes the hiss.

Malfunction: Interferences

The cause are always the wires. Especially the power- and signal wires are vulnerable. In most of the cases the inteferences will caused by the light generator of your car or other strong electrical devices. Avoid this by proper and appropriate installation of all wires.

Please follow these instructions:

1.Use only shilded RCA-Wires, which are designed for Car Audio Systems.

2.Install and mount all loudspeaker, line-signal and power supply wires with a sufficient distance to each other, also to other wires of the vehicle’s electrical system. If this is not possible, install the power supply wires together with the serial wires of the vehicle. The RCA wires should be installed with a sufficient distance to these. The remote wire could be installed together with the RCA wires.

3.Avoid any ground loops, by installing all components with a starlike arrangement. This means every component of your soundsystem needs a own separate ground wire.

If the malfunctions are still be on hand, consult your local Car Audio Retailer.

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. With their advanced technologies and solid build quality, these amplifiers represent a wise investment for any car audio system.
