Connect passive bookshelf speakers with passive sub to a laptop

[connorschwing]

I have two Pioneer SP-BS21-LR bookshelf speakers, and a Sony SP-WP23 subwoofer. The sub is passive and only has a + and - cable coming out of it. The bookshelf speakers have + and - speaker wire terminals on the back.

How can I hook these up to an amplifier and use it as a desktop speaker setup with my laptop?

Would something like this work?

Also, I fully understand that getting an active sub is better. I cannot afford that at the moment though.

That is exactly what I would suggest. Good job picking it out.
