especailly true when you factor the running cost of the subaru when all you use it for is to pop down to shops every week.
Given that lodore is talking about running his sound through a Hifi system with 2 speakers then talking about 4.1 up to 7.1 is pointless as he doesn't have the speakers to suport it.
My advice is to run it trough the onboard sound, then if you don't think the quality is good enough you should consider getting a sound card.
