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
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.
