SANTA CLARA -- The 49ers reward for beating the Green Bay Packers and Carolina Panthers on the road is another game in an unfriendly environment. And the upcoming game against the Seattle Seahawks won't be played in just any stadium.

CenturyLink Field has turned into a house of horrors for the 49ers of late, with the Seahawks beating the 49ers last season and this season by a combined score of 71-16.

Yet, 49ers coach Jim Harbaugh said Monday that he feels as if the path to Sunday's NFC Championship Game prepared his team for the challenge that lies ahead.

"Our team has been in a lot of good primers, been through a lot of situations, been through tough environments, whether it be weather or opposing stadiums," Harbaugh said.

Indeed. The 49ers are 8-2 on the road this season, including a 23-20 victory over the Packers in an NFC Playoffs wild-card game and a 23-10 win in Charlotte on Sunday.

They beat the Packers despite frigid weather and brutal conditions. A week later, they dominated the Panthers after flying cross country and playing before a partisan crowd for the third time in two weeks -- they played in Arizona in the regular-season finale.

The Packers and Panthers enjoy a distinct home-field advantage. The Seahawks are on a different level, though, Harbaugh conceded.

"There's a lot of loud venues; I wouldn't want to disrespect any of the loud venues," Harbaugh said. "But I would have to say that that's the loudest, yes."

The Seahawks lost only one game at home the past two seasons. That came against the Cardinals late this season.

Harbaugh likened his well-traveled team — the 49ers played in London earlier this season — to a country song.

"Been everywhere, man," Harbaugh said. "Just like something from a Johnny Cash son, 'We've been everywhere, man.' Everywhere. A lot of situations."
