i know i need to plug it into a amp or dac and then plug the dac into the motherboard but are there any good dacs or amps that wont break the bank but are very good quality? it would need an over all volume control and a bass control. please recommend some. thanks
It would help if you told us what speakers you were using. If the sub is self powered you need a sub out to connect it to, Something like this might work
They are not self powered. They all have male cables. On my current amp i have a left and right female port with another female port specifically for the subwoofer. It says subwoofer on the port.
