So I had to replace the rca from head unit to my amp and so since then when I turn off my car the sub and amp give a 1 second burst and if I turn the volume up at all i get a constant play from the sub I have installed plenty of systems but haven't came across this issue before so any help will be appreciated I just don't feel like re wiring everything so thats why I'm here asking thank you in advance for the information
