Really good amp for the price. I'm pushing a set of 6.5'' JL C2'S up front some Sound Storm tweeters in the back and also about to get some 6x9 Alpine Type S for the back. So far I have it turned up half way and its LOUD and clear. Cant go wrong with Hifonics amps.

This is a really great amplifier for the price, according to specs it says it can do 100watts rms x 4 at 4 ohms. Since its a pretty cheap price I'm doubting it but this amp does hit. I'm running this amp to 4 Hifonics Zeus ZXi6.5c components at the 100watts rms. It gets loud and clear, I'm very happy with the results, Provides a good amount of mid-bass and really bumps up the treble to balance out the bass from my two Soundstream t-5 15's running on a 2000 watt Brutus. If your looking for a inexpensive but quality amp to power your mids and highs or even a small subwoofer this would be a great amp for you! And if you are thinking about using it to power hifoincs components, buy it! Will save you a ton of money and have great sound too! People hear my highs before they here my subs sometimes and I'm pushing 900 watts rms to each sub! My windsheild wiperblades jump about 1/4 inch on each bass line!

This amp is great. Crystal clear highs come thru my infinity reference 6.5's and 6x9's. Great tuneability. My Jensen UVA9 dvd head unit was only feeding my speakers 18 watts rms and now they get 100 watts rms. Let's just say I used to set the volume at 38 which 40 was the max and well now its set at 25 maybe 27 if I can handle the bass. Great amp, great price, and best of all fast free shipping. A month into loud volume and no complaints here. Invest in this amp!
