Cause even if I got a high output alt of like 240 amps and my amp is pulling 140-160 amos just to make 1.2k  that's like 75 percent of that alternators output then my 4 channel I think has a 40 amp fuse. So 200 amps give or take.Vs a 2 ohm amp and 85-90 percent as most quality amps have around this efficiency at this ohm rating pulling around the same power would probably be like 110-120 amps for the 1200 sub channel and then the 40 amps for the 4 channel a good 40 amps less and the amp is gonna run cooler.At that point I could bump the amp up to like 1800 watts and it'd probably pull the same amperage to make that power at 2 ohms cause of the higher efficiency</blockquote>
