I've searched the forums for this question and I'm wondering if one of you good people could help me. My wife is letting me clear some space in the basement and I have some M22's I want to hook with an X-Sub to my Nad 352 integrated. Well, it is already hooked up running the red/white from the back of the sub to my integrated. The sub is working, but I'm wondering is there a better way to hook it up? Obviously, the integrated has no bass management. The X-Sub has a cross-over and volume control for those not familiar with the product. I guess I'm asking is it worth it to run the sub with the integrated and what settings should I have on the sub if anyone thinks it will work or not. Hope that is not too confusing. Thanks in advance for any answers......
