So I own a 2011 ranger xl 2.3l base model and I recently put in some aftermarket jbl speakers I don’t know shit about speakers or anything electrical for that matter but installation was easy and the speakers sound good if the engine isn’t running I can turn it up as loud as I want with no issue but if I start it and keep it at the same volume it crackles and pops. Im not sure if I’m not getting enough power to the speaker while running or something to do with my head unit , I have the factory head unit and unfortunately use an fm transmitter for music off my phone but idk wtf going on any insight would be helpful
