I was just wondering if these are worth it Also do you have to have the Epicenter Plus also with the Epic 160 to get the most out of them, do they both do the same thing? Or could I just Use the Epic 160, also how do you hook these up,, and do they take the place of your bass remote knob on your amp or can u use both and does it make a bigger difference when you use both remotes also do you use these only for the sub amp or could I use it for the mids and highs thanks
