(Not sure I'm following your second sentence as perhaps you intended it, as amperage is current, the way I'm reading you're saying amps don't matter much but current does? Again could be me, not trying to stir anything, only trying to help and discuss.)
The use of RMS on the 50 amp question leads me to assume you are referring to an audio speaker application? If so I wouldn't expect too much problem, as the average current/amperage/power will be far lower than that. I've seen audio setups not unlike that work fine (Apogee full range ribbons for example, luscious sound but incredible amp killers). Current carrying is limited by heat generation, which is far more related to average current than peak. Unlike the far more continuous high current when charging batteries.
I tend to use amperage and current interchangeable. Sorry if that is confusing to you. I'm certain that some of the bass heavy "music" you hear kids listening to will sustain pretty close to the full wattage their amplifiers are capable of delivering.
Anyway, I should probably stop mentioning audio stuff since it seems to confuse rather than help. I actually have some formal education in electronics but I was trying to give examples that everyone could picture.
I own a pair of the Dayton binding posts and the cross section is probably four times that of the 12 gauge wire Tekin included with my RX8 ESC. But I believe the binding posts are brass inside while the wire is copper. That means the internal resistance / voltage drop will be just over double that of a copper conductor with the same cross section and length. But I still think they will be fine for this application.
Op, if you try these and they do heat up on you, PM me and I'll buy them from you for what ever you paid and I'll pay shipping to me. I'm going to build a new sub-woofer enclosure for my wife's SUV soon and I can use them there, or in some other future project.
