Shanton L

Hello guys, I have a 2007 Lexus GS350 and I noticed that the VSC light always turns on whenever I connect my amp/subwoofer wire to the battery. Not too sure what it is triggering or if I need a higher voltage alternator can someone give me any suggestions or what can be causing it? All the lights turn off whenever I take the wire off the battery pole so I’m pretty confused what it is but I have an idea what it may be. I was thinking that I need a higher voltage for the alternator. Can anyone help me out here thank you guys so much. Hope you guys have a wonderful day.
