I have 300W+150W+150W Class D amplifier It require 48V DC
I have 24V DC (7 Amp) Output SMPS- 2Nos
Can I Use this 2 SMPS Output in series (24V+24V=48V) ?

Yes. However you're going to reach the current limit of your supplies before you get maximum power out of your amps.

Not enough current/power capability.
48*7=336VA while you need 800/900 VA or better to play it safe.

Depends. If the inputs are isolated from the outputs then possibly. If not then no. Make sure there are or you include reverse protection diodes on the outputs.
This appears to be a TPA3255 implementation, doesn't it? For mine I chose the Meanwell HRPG-600-48. Works fine! The cheaper HRP-600-48, which basically is the same, but without the 5 Vdc output, also will work.
Best regards!

That if he play sine wave at full input voltage.
But that 3255 will crap out long before current capacity reached.
If you need more current you may be able to find some old sever psu, I bought two they are rated 48 volt 76 amps, that should be sufficient
