I think it just depends on where you are. he ships with canadian air mail and they say 4 days. I think he adds the extra days to account for either sending it the next day if its too late, or it getting caught up in customs.
on a side note, what kid of things are suggested to add to the pa2v2? This is my first venture into amping and im not reallly sure what im doing other than plug everything in. Should i upgrade the wires going to it or not? I really have no idea with this stuff
edit: i ordered mine 12/29, but havent recieved yet. that was expected though. also, i got pa2v2 number 8000!!!
i like round numbers
