This amp is awesome for powering my high pass speakers. Just enough power to sound better than simply running components from my head unit. If you have experience in installation of car audio, this amp will be a breeze. My only complaint is that the terminals for power and ground are directly beside one another(unlike most amps, In which, the remote is usually in the center) This being said, I could see how easily one could fry this amp if they aren’t careful. This is a company from Brazil, but they do have a hq in Florida for tech support in the states. Great amp for about half the cost of most brands. I will post updates on how it performs over time. Great job Stemsom!!!!One month later and I figured out how to make this little guy go hard! These Brazilian amplifiers love the voltage from the rca cables to be on the higher side for voltage, so I put my signal through a clarion equalizer first to juice up the voltage, and let me tell you! Louder and richer than before. I don’t care if this amp fries, I have already got my money worth!

This little 4 channel amp is so convenient , I bought 6. They are great if you want more power than your deck or head unit can do, low pass high pass and flat settings. 4 channel RCA in 4 channel amped power out.Perfect for motor cycles. Crisp highs clear mid good ish SUB sound.

I purchased this unit for front and rear speakers. They are four and a half inch coaxial in front, and 6 1/2-in coaxial in the rear. There is a significant volume increase, but more importantly, it has made the speakers come alive. It is more than I would have expected. My only concern is that I noticed that I start to get Distortion that is not related to the driver break up, but more so the amplifier. My take on this is that if you want to drive your gear to excessive levels, you may want to get a larger 4 channel amplifier. Let me know that this is at 75% and higher on the volume slider (very loud). Other than that instance, this is a great little unit.

This little amp hits hard and it don't consume alot of power. I have two of them 1 for 4 prv tweeters and the other one with 2 6.5 prv midrange in Bridge and let me tell you they get loud and clear. Would recommend if you want Quality sound.
