Retro Look with New Design
The Hifonics HFi55.4 informs you of its main objective in the name, Hi-Fi audio. High end sound processing is the designs main focus, however it continues to bring value to the table by providing high power output in an pleasantly small chassis. The illuminating retro Hifonics logo brings an old-school look back into a new series.
This four channel HFi series amplifier integrates Pulse Width Modulated MOSFET power supplies to allow for affordable power, while causing minimal draw on your cars electrical system. Its bridging options allow bridging from their 4 channel down to 3 channels. This allows the amplifier to drive a bridged channel for a sub, and two unbridged channels for normal output for components such as door speakers. The bridging options also allow for bridging to two separate dedicated channels, to allow for high output to subwoofers, or high powered components.
This incredible power output is combined with the HFi series of amplifiers integrated high-dissipation heat-sink design, and built-in system diagnostics. Affordability does not have to sacrifice value or sound quality – making the HFi55.4 multi-channels the perfect choice.

I love this amp! I have it hooked up to 4 hifonics zeus 6.5 components. This amp runs them with alot of bass, and highs with great clarity. Of all the 4 channel amps i have owned this one is the best by far. In my opiniopn it is just the exact right amount of power for your mids and highs. It looks so cool when its on and lit up. Cannot beat the price anywhere. Some people say hifonics is lower/ mid grade stuff. Well, I believe their amps at least are top notch. Best price by far and i cant say it enough.

I never thought about using the Hifonics amps in a custom installation but I will tell you if you are on a budget and are looking for a quality product this is the amp for you. I resently installed a custom system in a customers truck with this amp and it sounds way better then I ever thought it would. I hooked 8 sets of 3/4" soft dome RF tweeters to this amp and it handles the task with-out getting hot or clipping. It also shows well if you are doing a show quality system as well.

I have this amp powering a pair of Kappa 682.9cf and Reference 9633cf by infinity and it sounds great, the speakers get more than enough power and the amp doesn't heat up.
