[QUOTE="honkyg, post: 8441175, member: 606879"] well, youve got 120amp total draw for your audio components,.. im sure it's not loading all at once, but it can on high volume and bursts. we can factor in a loss of voltage and amperage over distance through the 4ga. power wire, 10% is acceptable in the electrical industry. personally, i always go overboard on my electrical just to be safe and keep my amps well fed,.. think of it as if you were trying to **** a milkshake through a straw,.. too small a wire is like using a capri sun straw or cocktail stir. now, we also need to account for your alternator (provided it is stock) being given extra duty on top of powering your car's electrical. idk what you drive, but i can state that on average, alternators for passenger vehicles produce between 120-145 amp @14.4vdc, sometimes less, sometimes more. i think you may be taxing your electrical system if youve got a large amount of electrically powered accoutrements in your vehicle. once again, and i cannot stress it enough, do the big three if you havent already; 1 extra ground wire between engine block/head/alt case and batt, 1 extra ground between chassie and engine block/head/alt case, 1 extra ground between chassie and batt [/QUOTE]
