Your subwoofer crossover needs the big one. 400uF at 100V is the top of this Jaycar range and it's there for a reason — sub drivers demand serious capacitance to keep bass controlled and tight. The 50V bipolar caps won't survive the power draw here. This one will. RT or axial leads, so you pick the orientation that fits your board
