I have an alpine MRD-1005D amp running a single type x and if I run it with the car off and sometimes with the car on the amp will cut off and flash CUR if I turn it up a little loud. I was wondering what the problem might be? I don't have a manual so I'm not 100% sure what this is. I was running a pair compvr's before and it did it more often but I'm not sure if that has anything to do with the problem. any help would be great. thanks.
