I don't have a whole lot of experience with car amps, but my home systems have always been the envy. My friends would spend twice as much as me, and would eventually just have to concede that my system had the best sound. I know what I'm doing. My electronics background, and years as a musician with perfect pitch hearing is my gift. I feel I hit it right on the mark again in building my relatively inexpensive car system, starting with this amp!!!
The amp is clean, and loud. Plenty loud for the little Nissan I have it in.
In a larger sedan, I might want to step up the watts, but I like it loud. I have this pushing the two front, and two rear speakers, with a separate powered sub. It was stinking hot this summer, and it's stinking cold now!!! I had no problems what so ever. I didn't wait till the car cooled down any before I cranked it up, and the amp handled all that heat in my black car.
