Amp or head unit?

Question

I am getting feedback in my subs and I can't seem to get rid of it. Ive tried everything i can with my amp and it work for about a week after that but now im getting feedback again. Could it be a problem with the head unit? It is about 4 years old now and also has a couple of other minor things wrong with the head unit.
