I havent bought the Meanwell 48v 7.3A , still using brick 48v 5a which i suspect isn't up to the spec. I'll just wait for the multimeter I'm buying to check further tomorrow.Here is what you have with the bridged amp running on 48V into 8 ohms, at the point of clipping (ignoring losses). Red and Blue are the single ended amp voltages fed to speaker + and -. The difference between these divided by 8 ohms gives the green curve, current. So you see your power supply is tasked with providing 6 amp peaks. When running L and R it will be 12 amps. However, after looking at the data sheet of the supply you want to use, I think it can give you those peaks or at least close to it.

But based on what Raindog123 said, volume matters too, and since 9 o'clock is my sweet spot for listening so I think it doesn't matter much anymore since if more power coming and it's too loud then I will turn it down. I'll just test it for the sake of curiousity.
