i bought this amp because the one i had before it wasn't powerful enough and just wasnt good, this amp is by far the best i've ever had and all of my friends keep asking me where i got it and what the model is because it sounds so crisp and really can rattle the car whenever i want to. I have had no problems at all with it and was able to install it myself, which means it's pretty simple. If you want amazing audio, buy this amp
