Hifonics HFi 55.4 4 x 55 @ 4 OHMS, 4 x 110 @ 2 OHMS, 2 x 220 @ 4 OHMS

Hifonics offers seven newly designed HFi Series amplifiers, including four D-Class mono-block models, one 2-channel, and two 4-channel models.

Crowned with the retro style Hifonics HF logo, the HFi Series mono-blocks are all low distortion 4/2/1-Ohm stable highly efficient subwoofer amplifiers. They offer variable low-pass, subsonic filters, built-in system diagnostics, and a high-dissipation heat-sink design. They come equipped with bass remotes, and an illuminated HF logo. HFi mono-blocks are offered in the following configurations:

Complementing the D-Class line the HFi Series offers two and four-channel A/B class amplifiers. These amps are 4/2 Ohm stable, they are mulit-channel configurable, and they offer variable high-pass and low-pass. The Hifonics HFi Series amplifiers offer performance and value features beyond comparably priced products. All HFi Series amplifiers are built to exacting performance standards.

For 26-years Hifonics has offered superior performance and reliability that enthusiasts have become to trust. This HFi Series is a prime example of the car audio engineer expertise gained from Hifonics’ quarter of a century experience in leading edge mobile electronics products.
