Cold Weather And Voltage Drop

[TRTC360]

Well I have a DC3.5k on a pair of VVX-12's wired to two ohm, zero gauge, big three upgrade, 185amp alt and stock batteries, I know my electrical is not enough so I keep a good eye on my voltage, when it's warm outside and the engine has been running for a good while my voltage drop is anywhere from 11.5 at the lowest to high 12's on songs that don't drop low, today it's very cold and I noticed the same songs i've been playing sounded a bit louder (ears hurt a bit and I felt chocked up a little bit) I checked my voltage drop full tilt and wasn't dropping below 13's, why does the cold weather affect it so much? my car wasn't idling any higher than normal either.

Heat = power loss

Colder = less power loss

my voltage usualy is 14.2 in the summer after my engine is warm

in the winter when its cold, i generally have a fresh start voltage of 15.1 and after the engine is warm i drop to about 14.7, when i play full tilt i rarely go below 13.9 in the winter... its great
