Hello, I currently own the sony mhc-rx100av (one center speaker, 2 big speakers and another 2 small ones for surround movies) Right now i have an rca to 3.5 jack so i have it connected it to my pc./
My questions are,

Is my motherboard's audio chip good enough or the quality output could be better with a sound card? (my motherboard asrock z97 anniversary)

Also i want to increase my bass.(Except from the woofers the 2 big speakers have integrated) I saw that in the back there is a super woofer port ( i know old) So the only way to increase the bass is to get a super woofer? If yes any link from a decent super woofer?
 
Any self powered subwoofer is compatible. There is no such thing as a "super woofer" unless Sony offered an optional self powered subwoofer and chose to confuse you by calling it that.
Turn off any bass boost or bass eq that you may have been using before connecting the subwoofer. Adjust the bass level, low pass frequency, and phase on the back of the subwoofer not on the mini system.

On the back of it it is like this

If you see the bottom left that port. On the top of it it says super woofer

And with a quick look on ebay i found some subwoofers that are called super woofers like these

So do all subwoofers have the same port as the back of my sound central system? (sony rx100av)
