I would like to say this amplifier has been good so far. For 50 bucks you can't go wrong. It's been running for one week no issues to speak of. The thing that amazed me is the crystal clear sound quality it puts out. I have a good Kenwood head unit so that's most of it. Just pair this amp with a good head unit and you can't go wrong here for the price. I'm used to Rockford Fosgate amplifiers so I am experienced when it comes to car audio.
