Do you think there would be a problem running 2500 watts RMS through those posts into a 1 Ohm load? That should be about 50 amps.
Can't say for sure with no direct experience with those posts, but I suspect they might handle 60A continuous, while quite possibly getting warm. Assuming some air circulation and paying attention to their condition over time they might be fine, but I would want to test and confirm. (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.
