Retro Look with New Design
The Hifonics HFi100.4 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 HFi100.4 multi-channels the perfect choice.

It's good for its price. Had it powering a set of Hifonics ZXi6.5s on the doors. They sounded great but I came across a RF punch 400.2 and it now the components sound way better. I'd say this amp does from 60-80 rms a channel instead of the 100 RMS. But I will be using this amp for my tweeters!
Can't rate on durability since I used it for about a month.
