Barry Lewtas' side were full value for their victory and the young Reds produced an impressive display.
Paul Glatzel netted twice, including a penalty, debutant Bobby Duncan also registered a spot-kick, while Rhys Williams, Abdi Sharif and Jack Walls were also on the mark.
Reflecting on the win, Lewtas told Liverpoolfc.com: "The boys played some really good stuff and overall it was a good solid performance.
"We worked really hard during pre-season and this is a great start for us.
"We will have some tough challenges ahead but this win is great for the confidence.
