This amp works very well. I have it hooked up to 51/4 infinitys up front and 6x9 infinitys in the back and it pushes them very well. The only problem i ran into was hearing engine noise through the speakers. After long hours of trying to figure out what was causing it, it was the high input wires they give you to connect to your head unit. They are only to be used if you dont have RCA's coming out of the back of your head unit. I kept my factory head unit becuase it looks nice. a simple fix to this however is to get a 4channel line out converter and just run it with RCA's instead of speaker wire. Now i hear very clear sound from my speakers (no engine noise or electrical interference can be heard) and i am extremley happy with the deal i got on this amp and the quality. It does get very warm like every other amp, but i think i will buy a fan and hook it up to the power to keep the amp running cooler. Just remember not to use the high input wires they give you with the amp, they admit electrical noise.

This is an awesome amp that has many features and a price that offers much more than what you pay pro. The audio quality is great so if you are looking for a solid amp at a great price, look no further.

I bought this amp in hopes of more power to my door speakers than my head unit could offer. This thing has no more power than any after market head unit. I should've known when the RMS rating wasn't listed. If you're going to spend money an a 4 channel amp. Buy a reputable one. I own an autotek Mean Machine series amp and am way more pleased with it.
The only reason i kept this amp was because of the high pass filter. Other than that i am totally disappointed.

I have had this for six months now and so far so good, the sound is worlds better than the stock system in my Kia Soul.

I am powering a pair of Alpine 6-1/2" separates and a pair of 6-1/2" Kenwood coax speakers.

It drives my speakers fine and reliably.

I am using this amp to power Selenium PA horns on the outside of my car. Im running 8 horns @ 4ohms per channel. Sound is excelent. Plenty of power for my application. I would reccomend this amp for anyone looking for powering interior or exterior full range speakers.
