Afaird there no RCA at all. Looks like TV sound it will have to be.If the connection Box has LR Audio out on 2 RCA you can try connecting them to a Sub with LR RCA Input plus Crossover and Level settings and try running the Sub plus the TV speakers - you will use the setting controls on the Sub to adjust where it start to operate and its loudness relative to the TV speakers.

You could use the Optical Out with an Optical to 2RCA Converter into a suitable Sub - the one worry being will the TV Speakers and Optical Out stay 'in sync'.

Afraid I never tried anything out, turns out this TV was mostly used for watching breakfast TV, so quickly lost interest in improving the sound.hey Jeegnesh, just bought a Q95T and was hoping to do the same, maybe optical out directly to the sub, but not sure if that turns off TV sound or has sync issues. - did you ever find out?
thanks
