well i only get two numbers on my gauge (18,8 ) so i don't know exactly but it would go from a little above the half mark, approx 14-15 and drop to a little below the half mark, 12.5-13.5. it was only deep bass like from rap songs that did it. i'll prolly do the three in my z but for the v6 its a beater so i don't really care plus the system is out of that one and in the z. when i start driving next week ill see how the alternator performs. it looks kinda old so i'll give it a load test tomorrow at work and see what's what. if i replace it, i'll do the three.
