Hifonics HFi100.4

Pretty good

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.

Hifonics

I was able to tune it to my EQ, very easy set up...one down fall...goes into protection after a while on hot summer days

Not bad for the price ...

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

Great Amp

Has lots of power and sounds great.

Good Amp

Great amp although it does get warm, puts out close to what it says.

Very nice.

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.

worth the money

Good amp. Clear highs. Have had it for 1 year no problems.

Best amp for the money

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.

great amp!

I purchased this amp to replace a 780 watt 2 channel pioneer amp. I have it hooked up to a pair of Alpine components in the front and SPL components in the rear. ( also purchased from SONIC) And I can not be happier. There is plenty of power and clarity. The Amp puts out a great deal of power and do not distort. Great amp for the price no complaints on it. I have been beating the heck out of it for several months now and it does not sweat.

HFi100.4

I purchased this amp to power a pair of planet audio bb690's and a pair of Alpine spe-5000 and they sound as clear a a bell.

Love it!

I love this amp. It sounds great in my truck. I was looking for an that wouldn't over heat in a small space, and this amp has given me exactly what I needed.

High's on a budget

Works great, i have not had any issue's with this amp at all, this was more than enough power to run all my MB Quart high's that I also purchaced here at Sonic. Thank you Sonic. I would reccommened.

Awesome Amp

This is my second Hifonics amp that I have put in my boat. The first one lasted over 7 years in marine conditions. I am sold on them. Great product

GREAT FOR RUNNING MIDS

Connected this to my mids. 2 6.5s and 2 6x9s. Would recommend to anybody looking to really boost their vocals!!

hifonics hfi1004

Works great, powerful great amp. The sound is clean and crisp. I would suggest running a very heavy power cable. Also have a good battery and terminals and fuses. This is a power hungry amp. Do not go cheap on any of the things I mentioned. You are supposed to use a 0 gage cable even if the cost is high you want it for a reason.
