Let me start off, I received this amp as a gift from a family member and was purchased through Best Buy. I installed the amp this afternoon and everything seemed fine. I also installed 2 brand new Dxi104 dvc's at the same time, As said in the manual I played music at little less than medium to run them in for about a half hour. I had the gain turned to about 1/4 of the knob. I checked the amp several times to make certain that it was not getting hot. After the half hour, It worked flawless and sounded killer. I turned off the truck and went in. I came back out about 1-2 hours later and the amp was in protection mode. I checked all the connections and fuses, I even ran a new remote power wire and still the same. I am missing something? Is there anything I should check? I disconnected the power wire and I am going to leave it off until I can figure out something. Thanks.
