Class D circuitry needs careful attention paid to layout - a breadboard won't do. Try to get a PCB made with the application circuit.

Best chip for CLASS D in very less time is LM3886. U can wire it on breadboard and it works. Very cheap PCB are available in market . Output is great compared to market.

LM3886 is not a class D device at all. It is a quasi class AB power amp on a chip. Also it runs hot, especially if you push it hard.
