First of all sorry if the thread is in wrong section
2ndly, hello i am new here . First post
Now, on topic,
I just happen to find a really old 8Ohm 75RMS phillips subwoofer lying around.
i have the sub only, nothing else.
Currently i am running this thing with a cheap tpa3116d2 board
Running with a 24v PSU. But if i am not wrong i am getting max (24x.6x24x.6)/8 = 26w RMS
i want a cheap amp which can drive it to the max potential.
I can have 36v PSU but strictly DC.

On a 24V PSU you'd max out around 35 watts RMS into 8 ohms. Probably less.
At 36V if the chip doesn't mind it, you might get 75 watts.

mate, AFAIK TPA3116d2 can be driven @max 26v so, yeah i am stuck @24v with it, thats why asking..
Yes, it looks like a good choice and should not have a problem at 36 volts.
Check the datasheet to see if you can connect the outputs in parallel. That can help if you are just running a single woofer.

Yes bro even if i am a complete noob on this matter, i tried to research and found couple of boards.
Could u guys plz take a look...

Any other recommendations. And about caps , are they 50v caps?

Well i can afford it.
But what do u know..
just imagine a person from a third world country who is currently jobless for the pandemic ,pursuing his hobby 😛
I'd probably got 32V from a typical board spec - 35V capacitors fitted.
TDA7498E boards usually fitted with 50V capacitors.
