Where to Find the Best Basic Physics Books for a Deeper Understanding?

[americanforest]

Do you guys know what book would be the best for learning basic stuff (mechanics, electricity and magnetism) at a much higher and more detailed level than Halliday. I finished the Halliday text and feel like it was very shallow. I'd like to get into the details of the math and physics behind the ideas in there.
