I was driving when randomly my CD deck turned off while playing sub woofers at high power. Once my CD deck restarted I turned down the volume and then my lights started to flicker. I turned my deck completely off and while driving down the road, my head and interior lights flickered on and off. I had my alternator and battery replaced about 4 months ago. Any Ideas on a problem and solution?
Chec battery condition first and then clean all grounds then you might check to see how much power is draining on your sub woofers/cd. It may be more thatn the alternator can put out or to much for the battery as well.
