connecting a set of bookshelf speakers and a sub to my computer

[michaelbarrett4444]

i have recently purchased a set of Monitor audio Bronze 1 (which apparently need speaker cables to work) each side has a positive and a negative and on top of that my subwoofer needs a sub cable. this all somehow needs to be connected to my computer with the standard cables that are avaliable ( no banana cables or sub cable connections). how would i go about connecting it all together? btw my speakers cannot connect to the subwoofer as the sub only has a single input port

The subwoofer could be connected to your motherboard with an appropriate 3.5mm to RCA cable. The bookshelf speakers will require a separate amplifier. Something like this -- https://www.amazon.com/%E3%80%90Update%E3%80%91-Audio-Amplifier-Receiver-Integrated/dp/B076P2VS9H

What motherboard do you have?

Another option would be to find an older surround sound receiver. One without HDMI you should be pretty cheap. It will have a subwoofer output and remote.
These mini amps have very sketchy power ratings so they are often way overated with a lot of distortion.
