Would a fellow harman kardon AVR-525 owner please take a minute and get a rear panel measurement for me? Here’s what I need. As you are looking at the rear panel I need a measurement (inches) from the left side of the case to the “Subwoofer Pre Out”. Also, I need a measurement from the shelf or floor the unit is sitting on to the same output. I need these measurements because I am going to have to cut through the rear of my electronics rack due to a severe depth issue. Thanks!
