Problem Hook up Logitech Speakers to TV

Would depend on what the resistance is of the speakers,if they're 8ohm they most probably won't work,then there's the issue of running the sub,the tv isn't meant to run it.I would expect a amp or an onboard amplifier to do it.Look at this way if the tv can run 2 mid range speakers that are compatible then that tells you the tv port is ok

 

Either way i need a amp to accept the speaker wire, i am going stay with my current set up thanks
