Hello, I was wondering if you guys have any thoughts on the Big 3 Upgrade. I have a pretty powerful audio system, over 1000 watts total, and my headlights flicker with the bass. I looked around and the best fix would be this Upgrade. The upgrade is basically using 4 gauge wire from the battery negative to chassis, from the alternator to battery positive, and from the chassis to engine. Thank you!
