Can I use a 3.5 to RCA adapter to connect an aux sound outlet to an old speaker system using RCA inlets?
If so, what about the quality of the sound I would get? Thanks in advance.
If you have an amplified speaker system -- which should have RCA inputs then you should be able to do this. If you don't find a TV you like with analog outputs (RCA or other) then you can use an adapter which will take digital output (optical or coax) and convert to analog.
