I have owned this amp for almost 2 years now. So far, it has treated me very well. On a hot summer day, I have to switch the AC on, and direct it to the floor(it's under my passenger seat). I feel that it gives pretty reliable power output. I have a seperate Boss amp driving my 2, 12" subs, and this one drives the 4, 6x9 speakers - (2 kenwood 500W 5ways, and 2 500W Clarion 4ways). Overall, I am very happy with this purchase. My friends hear Lanzar, and they make fun of me, but i'm happy. I started this evening looking for negative reviews to see why people looked down on this brand, but found nothing but great reviews. I don't know what people are talking about.
I would have liked it, however, if there were an option to control the crossover for the line out, as that is what I run my subs from. This is why I rated the features at an 8/10.
