I Love Hifonics

First off Thank You SE for having such great prices I went to a local shop and saw this amp for alomst triple your price. This Amp is GREAT coming from an audio engineer you cant buy a better amp at th9is price range, this easily competes with the Audiophile Amps costing thousands,

Clean sound!

The following review is for a previous version (ZX6400).

This amp turned my Type-S series Alpine components into Boston Acoustics in my opinion! I know another review says it's not enough power, but the efficiency of your speakers has alot to do with it. This amp has power, and plenty to spare. I'm only running it at 4ohm per channel and it's so clean. Runs cool, no problems there. And I'm sure if I wanted to, it will have the grunt to toss around some subs due to the Low Pass on it. I would recommend this as a highs amp, sub amp, or both! Bridgeable and flexible. What more could you ask for the price?!

Awesome Amp!

this amp is really very nicely built and has more than enough juice for any speakers. i have it pushing alpine type r components in the front and type r coax in the back and its really crisp and clear and loud. there is not any distortion and also the amp never really gets hot. so overall its a good amp and u wont regret buying it.

FYI Revised

The following review is for a previous version (ZX6400).

This amp IS NOT as powerful as many think. To get it to run my highs loud enough for me. I had to Parallel my left [front and rear coaxials together] (and the same on my right side.). To the 2 bridge channels (from bridging all 4 channels) from this amp. Now it’s loud. But running one channel per coaxial (4 channels on 4 coaxials) was very weak to me. In comparison to my old P.G. ZX 350 @ 2 ohms. Caution only do this with a radio that has hi-pass RCA outs. Then Activate the crossover on the amp. And use A Bass Blocker per coaxial connected in this setup. 100-500 micro farad, or speakers could fry. Even now with my system up about 94-100% I can smell near burning voice coils. But I just might have my amp gains up a bit too high. The two 2 ohm mono's won't hurt the amp. As long as u set it up exactly the way I've explained. It will only heat the amp up a bit. Sound Quality (of this amp for pushing highs) is not all that.

Awesome.

Great Product. Well worth the money. Skip buying anything more expensive to power 4 channels. More power then stated.

Another great innovation from Hifonics

this was my first hifonics purchase i made and i planned on making more later on, but this amp sounds unbelievable teamed up with my kenwood excelon XXV-01D head unit and excelon speakers, i have never heard such clarity before, truely an amazing innovation and plan on purchasing more Hifonics items soon.
