I have had this amp for about 9 months and bought it on this site. On a side note, don't bother with other sites these guys rock! Ok about the amp. I have the main volume controls around the 11:00 position so not pushing it too hard. The sound is warm and great, I am pushing 2 kickers 5x7's & 2 polk audio momo 5.25 speakers. The only time it went into protect mode was when I was listening to an IPDO 128 MP3 file and it was distorted. After turning the head unit off and on it came back on. This amp is huge and heavy. I will admit it gets quite hot which worried me at first but works fine. I listen to loud music most of the time so this amp has been pushed. I was amazed to see that the price has dropped - guess for a new model. I would recommend this model for anyone on a budget who wants good power.
