Subwoofer Amplifier with Power SOCL 500W

In this project, I will make a special power amplifier for the subwoofer speaker that I use for a power amplifier circuit that is Power SOCL 500W which use 2SC5200 and 2SA1943 final transistor 1 set/pair. Then for my subwoofer preamp use 4558 subwoofer filter/ 4558 subwoofer module. For power amplifier and subwoofer filter, each requires different power supply voltage. This power amplifier can
