I was recently given a Bose ps48 powered spkr system. Powered sub and 5 cubes w/wires. I think it originally came with a lifestyle 35 but there was no control module. I would like to use the spkr system for my computer. The input for the sub is rj45. I have the original input cable, mini din-8 to rj45. Is it possible to make/buy an adapter to input a line level signal (1/8 headphone jack or component, rca). If so, any help on the wiring scheme for the rj45 input on the sub or the original input cable would be greatly appreciated.
