Big problems with stereo today
Ok so my stereo has worked perfectly and not been changed for at least 6 months now. I never had any problems until today. I was cleaning out my trunk and decided to pull the sub box out to clean so i pulled it out then put it back in and reconnected when i was done. Ever since then nothing seems to work right. I have loud engine whine now which i have never had. I have loud crackling and popping at random times and when amp turns off. Sub will start soft and work there way up to very loud volume knob has no control. I have been screwing with it for an hour or so and havent figured out much. Any help would be wonderful. Ask questions for more information.
