Hi, i am running a small TPA 3116 stereo board with two TPA 3116 chips to feed my subwoofer (240 watt) on a 24 volt 4 amp universal notebook PS. Is this enough current or is it better to buy a switching supply 24 volt / 10 A. ? I am in dought if i get better bass performance with a stronger PS. Thanks for the input.
subwoofer is 2x 4 ohm. Two pairs of 8 ohm bass drivers, 4 total, with a 2 chip TPA3116 board stereo driven.

With 4 ohms load (3min) , each output max power is 90w. With 90% efficiency, you need 200w power supply. Indeed you need a 10A.
