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.

Pretty good

The following review is for HFi100.4, which is a part of the bundle you are viewing.

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.

Best amp for the money

The following review is for HFi100.4, which is a part of the bundle you are viewing.

This is the best amp for your mid's and high's for the money. I have owned it for 6 months and I would recommend it to any one if you are a beginner or like me have thousands invested in your system you would not be disappointed. The other neat trick about this amp is that if you get eight 4 ohm speakers you can actually increase the 400watts output to 800 watts pushing all eight speakers with no problem and trust me you won’t need more power than that. This is the best little amp for your money.

Very nice.

The following review is for HFi100.4, which is a part of the bundle you are viewing.

Well only having this installed for 2 days so far, I must say im pretty impressed. I have it in 4 channel mode powering 2 sets of the T1652-s of the R. Fosgate components. Easy install and setup. Pretty cool here on the East Coast atm but this amp can and does get really hot. I love the amp it works exactly how I want and need it too. Overall I would recommend this amp for a fairly cheap 4 channel. So 2 things that I have small issues with is the amp getting hot and at top volume for long periods of time the amp will lower its output due to being hot. And yes I have it in a well vented spot in my trunk.

Not bad for the price ...

The following review is for HFi100.4, which is a part of the bundle you are viewing.

Recently purchased this amplifier and to be honest I don't think the RMS values are accurate at all ,... like a recent comment I read, I agree that the values are stretched a bit ... I put these numbers to the test and this amplifier did not hold up at all but for the price it does its job, just don't expect 400 R.M.S. out of this amplifier bridged
