[QUOTE="johnecon2001, post: 590648, member: 556589"] Sorry to completly avoid your question at first... but what gauge wire are you running for the big three? Also what gauge are you running from the battery to the amp? Have you tried going to a larger gauge? In many cases the larger gauge can solve even the slightest dimming problem. Also, how old is your car? If the elctrical system is worn down after years of use, no matter how many little upgrades you do (big 3, new batt, bigger wire) you will still get that little annoying dimming. The only option for an older car in most cases is to either have the alt rewound/rebuilt or go and purchase a higher output alternator. However to answer your question..
