suggestion for Cable

[Parthiban]

Hi All

I am look for a cable to connect my Multimedia speakers.

Let me elaborate it,

I have bought Philips TV model : 43put7690/V7, it has Audio output as 3.5MM jack which can connect to Philips SPA6600 5.1 speakers in Auxiliary port.
Sound clarity looks poor compare with Airtel DTH audio to Philips SPA6600 5.1 speakers in Auxiliary port.

Now i have decided to give both TV and DTH connect to Philips SPA6600 5.1 speakers. When i select DVD Mode in Speakers it must play DTH sound, when i switch to AUX mode.. it should play TV sound.

Could you please suggest a cable for it.

Can i get cable like 3.5MM to 5.1 RCA cable or 2 RCA to 5.1 RCA cable

Thanks
