Well here is the situation. I just got all new door speakers for my car and put them in. Well i decided to hook up an amp to it also. The speakers i got are DXi650 I got 4 of them. The amp i got is PA 660. I have had them for a little over a month and my speakers are cutting in and out. My front right speaker doesn't work anymore. My Front left one cuts in and out and now my left rear speaker is cutting in and out. What would cause brand new speakers to just start going out? Any Suggestions on what might be causing this issue???
