Working fine at first, but it seems to run hot (and I am just entering my vehicle and maybe in it for 30mins) and the protection is too sensitive. I either have the volume down on the amp itself and try to listen at a decent volume and since it's hot where I live now (summer time) I can hear my A/C over it. I turn up the volume on the amp and the protection pops on at vol lv 15, and it's not even loud. I understand there is a difference with current music and the older (back in the day) music. The recording was different, better equipment now. In other words, older music you may have to turn it up a little more. But that's not my case! I had a Rockford Fosgate that gave no probs...going back to!
