Bose Acoustimass 4 with Technics Amp (1 Viewer)

[meister]

Hi, I have bought a second hand Bose Acoustimass 4 System which has 3 cubed speakers and one sub. I want to be able to use the system for playing dvd, blu ray and audio. I have a technics amp which is part of separates with stereo and surround speaker output which I would like to use with the setup.The tv has phono out/hdmi and a sub output.I currently have the the blu ray and sky box connected to the tv via hdmi.Do I need to buy an amp with a sub output for te bose sub or can I use the output on the tv? How do I incorporate the 3 cubed speakers with my amp?Many thanks

Model numbers please(or pics of the rear of this Technics...if web searches turn up nothing)

A TV having a phono output makes absolutely no sense.
