If you can play a CD test-tone or set-up disk through your TV speakers, you can measure the frequency responce where the TV speakers naturally roll off the bass. It's best measured with a analog sound level meter with the test disk but you may try it by ear and get lucky. That should locate the near perfect crossover point for the sub to match the TV.
As mentioned by others, the 2 subs can be split on the TV's SUB OUT with a Y or T connector. A true 5.1 matched system will offer much more in sound quality.
You may have a couple settings in your TV menu to assure the sound is correctly being processed with the added subs.
