[QUOTE="John Moore, post: 97841, member: 610"] Re: Power Feeder and Voltage Drop Look at the specs of your sub amps...at 1/3 power rating they are going to draw close to 30A in that mode...#6 has a power rating for transmission of about 40A and once you start adding length to the #6 , down you go (an we have not even addressed the other amps yet)...unless you have the subs on separate legs os a single phase distro with 2 hot legs...you are grossly under wired for what you are doing... 2/0 is going to get you almost 200A. Best thing to do is to get a current clamp meter and measure the load as you are doing an event...as we don't know how hard you are driving the amps...if even to 1/3 power... Or....it may just not be enough rig for the gig...we had a PV rig and found that you need a sub for each pair of top boxes...so maybe adding another set of subs to get the low end you are looking for...we used similar 6 tops per side and the 112 boxes did well...the ribbons didn't project as far as we hoped...
