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,

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.

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.
