[QUOTE="Water Bear, post: 8822044, member: 673826"] 11.9 is something like 40% battery charge for a 12V battery. That's pretty hard on them. If you drop there gradually over a song then you need an extra battery. If you drop there in a sudden spike then you need an ultracap. In both cases, get something good like XS or Ioxus. That's my guess. 240A alt is probably good enough for 2k watts or so. It's possible those Rockfords are underrated and you're actually getting much more than that wattage. [/QUOTE]
