I want to use HT system as an amplifier for my pc

[DzOnIxD]

I have a Panasonic sa-pt160. It has 4 regular speakers, 1 center speaker and 1 subwoofer for a 5.1 setup. The problem is that it only has one stereo and one scart input. Can anyone tell me if it is possible for me to use more than 2 speakers from that system? I don't want 5.1, but I do want to have a woofer.

the sub will work anyway. probably all 5 speakers can be used with dolby pro logic mode.
but this HT does not allow true 5.1 from external sources, only from discs.
