are the front and rear speakers suppose to have the same sound quality becuase mine dont the rear ones sound like ****
You need a card to support it first, and plug one into the out and tell your card to override it to 4.1, you won't get 5.1
The quality should be the same. The speakers in the rear will have a tendency to be quieter just like you can hear things in front of you better than behind you.
The rear speakers are for ambient sounds. The sound fired on the front speakers are for something like movie characters' voices. The rear speakers are used for ambient sounds like a passing train, traffic, etc. Sub woofers (the 1 in 5.1) is for low frequency which gives you that rumble (when you hear a thunder). If you have your set up correct, you should not be hearing the same sound from your front speakers to your rear speakers if you are playing a 5.1 source. You would hear the same sound from all speakers if you set your audio settings that way. Hope this gives you an idea of what the rear speakers are for.
