so i got the mackie cr3s and they don't have much bass so i thought i should add my old sub to it but i don't know how since i don't know much about audio, also i'm connecting them to my PC. any help would be appreciated thanks.

It is not going to work in the way you think. Mackie speakers have to subwoofer output, and the subwoofer you have is a passive one, powered by the speakers it is connected to.
