After installing my new sound system my battery light is coming on after i turn it up for a short time. I have 2 amps one is 1800 watts and the outher is 720w. I have a 6000w cap installed and new battery. All the int. lights dim as well as my headlights . does any one alse have this problem? and is it only a warning for more power than usualy used. if i turn it off and back on it go's away.
