Was it powered up or not, i.e., did you short the power switch to power it up? Do you now have audio or other problems with your system?
I'm not sure if it was powered up.
The sub has a power cable that plugs into a normal outlet or power strip. I plugged this in.
There is a port on the sub so it can be connected from the sub to an audio jack, (says speaker on the sub) I plugged this into the different audio jacks on the motherboard.
Then there is a third wire that goes to a power box module. That wire was cut and there is no power box module.
Here is the exact model on Newegg so you can see pictures. http://www.newegg.com/Product/Product.aspx?Item=N82E16836121010
As of now I have tested all audio ports on the motherboard and all seem to work fine. The only one I haven't been able to test is the "Line-in"
Probably no damage?
Your thoughts are appreciated.
