I want to connect the regular aux cable from Sony TV to Bose speaker in the aux input. When I tried doing that... Not much changes in sound out put effect.. Am I missing something here.. What needs to be done to fix this issue. Or does it need an amplifier.
If your speakers are not powered, yes they need an amp to power them. You may want to put in some info about what model speakers you are using and what connection on the TV you are using.
