Jared McCann scored his 27th goal, Jordan Eberle and Ryan Donato each had a goal and an assist, and Philipp Grubauer made 23 saves for the Kraken (26-48-6), who lost their fourth straight.
McCann gave the Kraken a lead 1-0 at 18:59 of the first period on a one-timer from the left circle after a Yanni Gourde pass from the corner. The Kraken outshot the Kings 12-2 in the period.
"I don't think we should have put ourselves in that situation," Los Angeles coach Todd McLellan said. "I didn't think we played with any purpose that matters. We played because the game was scheduled, and that was really it. We weren't getting any better. We were forming bad habits and we had to talk about it between the first and second, and then after that I thought we began to play with purpose.
"[The Kraken] play a heavy, hard game, tough team to play against. They tested a lot of our players that needed testing that haven't played for a long time or been injured. And a lot of our guys needed that."
Donato made it 2-0 at 2:24 of the second period when he skated right to left in front of the net and scored when Quick went down.
"When you score goals, sometimes you think it's going to be an easy night," Donato said. "Not pointing fingers at anybody, but the whole team. You take a couple of shifts off and those come right back in your net. So for us, we're not good enough to take shifts off. We've got to make sure we're attentive every time, and we weren't."
