[QUOTE="loopkiller, post: 5484365, member: 601690"] What is the efficiency of your amps? Are you playing music or test tones? What volume are you playing at? How much and what size wire are you using? How many other batteries are in the vehicle? What is the resting (open circuit) voltage of each battery? I think you get the point. There is no easy way to calculate that for you. There are just too many variables to think about, or even calculate. If you really want to know, follow these steps: 1) Connect the battery 2) Turn on the audio 3) Watch the clock [/QUOTE]
