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.

Great amp for the price..
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.

Good sound but not really enough amp to push sub
The amp I got had great mids and highs 234 channel switch was broken I would recommend this amp to push 4 Fosgate 6x9 punch speakers or something like that not a sub Maxxsonics says power uprated 20 percent broken switch prob. A fluke if u want old school Hifonics take a pass on hf series go Zeus or Brutus depending on your wants

Great Amp! Highly Recommended
I was told these amps were the lower end amps, but I got it because of the price and I'm stubborn and I don't regret it one bit, it looks cool because it lights up. My highs sound so much better, very reasonable price, and never gets hot. If you are looking for a cheap amp but still good quality go with this amp.

Good amp maybe
I have this amp running four Hifonics Zeus ZXi 683 (85 watts rms @ 4 ohms) it does good under moderate load but if you crank it up the amp heats up and sounds washy. I still have to play around with a fan and other things to see if it helps but was shocked that it heated up so fast in a well ventalated area. also not sure if I lost a channel of if a wife got jacked but I only have three speakers working right now.
