Just installed my system with a friend about 2 weeks ago. We did a pretty good job, but the only problem is my lights dim incredibly at night time. I have a 12" woofer pushing close to 400 watts. I'm getting a Capacitor to store more power, but will my altenator be able to handle it, and will my lights still DIM when the bass hits? Some say yes and some say no. I need one of my fellow enthusiast opinions. Let me know. Thanx!!
