Did the big three volts are high when cold.

[bass head 4-15s]

I have a 2001 ford expedition I purchase a 200 amp alt from ebay I got two batteries in the back,

and one in the front I did, The big three now when crank up in the morning my volts are about.

15 when cold and it comes down to 14.6 when warm I use a dmm to make sure it was right.

Is this normal.
