Please Help: Audio Settings

[WBdink]

So I upgraded my TV with a Bose Solo TV Sound System, it was a little over $400. Here's the thing though, the Audio Settings in GTA 5 for Xbox 360 (as most games) give you an option for TV, Speakers, and I believe Headphones. However, the Bose I bought is a single unit with 4 speakers in it and when I select Speakers in GTA it asks me to configure where in the room the speakers are but I cannot select straight ahead only, you must also choose Rear or Side in addition in Front. Am I making sense? So do I select TV or do Speakers and select Front and Side?

On a side note, my Battlefield 3 offers, TV, Hi-FI, and Home Theatre, What would I choose in that case?

Here's a link that shows the Bose and the specs: http://www.pcworld.co.uk/gbuk/tv-dvd-aud...

Thanks in advance!
