ill explain the whole story i was going and had the system on and i looked down and seen the battery light was on so i look and it say its around 12 volts so i turn the music off (even though my voltage never droped from it before its only pulling like 40 amps) and the voltage stayed at 12 i pulled in a parking lot and check the battery and it seemed fine so i just drove to toco bell. after it started up fine with no problems but the voltage is still in the same place
