For example, this one is only a 10$ 100watt class d at 4 ohms. That would work for the sub build but is it any good? Spending a few hundred on making a sub and then throwing in a bad amp because it does not cost much is crazy.TDA7492 2x50W D Class Digital Amplifier Board AMP Board With Radiator - US$9.35 - Banggood Mobile
Efficiency, switching frequency, modulation scheme, PSRR, CMRR.
But why not give the TDA7492 a try. 🙂

Thank you for taking your time to teach me about all of this. I appreciate it. Between you and Pafi I feel confident about constructing this sub. 😀
Seems like most class d modules don't give any of those specs so I will have to do what you say, buy them and try them out.
