when i traded for one i was told by a guy who ran them (cant remember his name but he ran like 8 or something) that they are better for 14-16v setups not 12v and dropping to low can damage them. i sold it .............
i like they way they look tho love long amps lol
and that electrical you listed wont even work that well on 1 they are 4k rated but will prolly pull 250-300a wired at 1 ohm
i was told DONT wire below 1 ohm on 12v and DONT drop below 12v lol
