    This is a great Amp! Just wanted to get something for my son first car. He doesn’t need a stereo system that is going to be too loud. This Amp fits perfectly

    Even though a bit less power than I wanted, it is a performing product for my (4) JL Audio c5-650's. Saved alot on install, and a very low noise ratio. Prob need a sub w/separate mono amp, but the alpine sounds GREAT

    Sounds great for the price.....the guy who installed it at best buy was not the brightest bulb being he did not adjust the amp properly so I had to go back......sounds great in my 2013 ford focus matched with polk dxi speakers. Fits behind the factory CD player so it's completely out of sight
