Are you really expecting to draw 60 amps through a single pair of posts? If not, I would suggest just adding fuses inline for slightly above your actual expected amps per pair of posts.
I made a 12V 32 amp PS Saturday from an old ATX PS I had stuck in the closet. I'm just planning to build a wood box around it and use it as a stand for my 1/8 scale buggy though.
While I agree a reasonable set of posts can handle a fair bit of current, audio power doesn't translate all that well to battery charging power for a couple reasons. One, the 1000W subwoofer current is likely not real high, even a 2 ohm driver would be a little over 22 amps. And music tends to be highly dynamic, with lots of quieter passages in between peaks, the average is much lower with cooling time between the big spikes.
