TPA6404-Q1: power supply decoupling capacitor

Part Number: TPA6404-Q1

Hi TI expert,

I am using TPA6404 in a automotive infotainment product, this speaker PA in integrated in a head unit PAD, the PCB area is very restricted and height is small.

My question is, I see that TPA6404 is a closed loop class D amplifier, it has 75dB PSRR. So can I lower the bulk decoupling capacitance? On TPA6404 EVM, it uses 330uF. Can I use, say 220uF or even 100uF?

If I use only 100uF, what specification will be influenced, THD?

Thank you.
