[QUOTE="jdavis37, post: 2553372, member: 557902"] I'm far from an expert on this subject but do deal with math and comparisons on a daily basis. Going from 5 to 8 is a 60% increase ( (8-5)/5 ). Going from 2 to 5 is a 150% increase ( (5-2)/2 ), so the 2 comparisons are not the same. I can't say how significant the 8v is to the 5V output ( Eclipse went with 5 V on thier higher end head unit versus the 8 of the 5000 ). Certainly it would affect the amount of gain needed on the amp to a degree but not nearly as signficantly as the 2 versus 5 argument. Others here are better equipped to answer that question. But, in this case you cannot compare the voltage difference in absolute ( ie 3 volts ) terms but rather must view it in relative terms, as in a % change. [/QUOTE]
