So I disconnected the negative terminal, installed the new sub, amp, new ground etc etc. then when I reconnected the negative back to the battery now I have multiple lights on my dash. My power steering light is on, hand brake light is on, traction control light on, ABS light on and my cruise control doesn’t work. I have tried disconnecting the negative for 10 minutes and nothing. I have disconnected both negative and positive for 10 minutes and nothing. The vehicle drives fine but lights are annoying. I went to autozone to check the lights and they told me an ABS sensor A was bad but never had that issue until after the install.
