I am thinking of upgrading my fronts to MS 908's which include the sub woofer. I've had a look at the online manual but am confused about how the subs should be wired. If I take the sub Woofer line out from my Marantz 5200 amp to one of the speakers does it also have a line out to connect to the other front? Have both speakers got a line out so I could connect to my existing sub as well? Any views on these speakers would be appreciated.
