Just hooked up an amp and sub in my 2010 mazdaspeed3 to the stock radio and everything is working perfect on it. Well today when i turned of my car when I got to work the subs made a really loud buzz for about 5 secs then turned right of as soon as the keys were out. What is this coming from? I just installed this last night and it didn't do it to me at all last night as I tested it twice. Can someone please help.
Its dont happen when I drive the car or turn it on it comes on right when I turn the car off.
