[QUOTE="akheathen, post: 7485549, member: 629234"] well, what is the impeedance load for the max rms? what ohms are you running on ylur sub(s).... amps are rated different, but one thing to look at is the fuse rating...the maximum output is only going to pull amperage less than the fuse rating. as a rule of thumb- i look at 80a as 1krms just fine. a high output alt would be ideal, but probably not quite justified. 2k, definately, but i doubt you will be drawing all that current that the whole car takes up all at once. i run 1160rms just fine with a 165a alt, without dragging the alt down into the battery, and it doesn't sound like you want to abuse it and drain your voltage down, either. i say, look at your voltage when playing at leisure. if you are getting into the mid 12's, then you are really working the alt, and pulling the battery down, which could call for new alt, and/or battery at any time, or even damage the equipment. then decide [/QUOTE]
