I have a problem with my Wharfedale ics191, as far as i can see i have nowhere to connect a remote cable for my aftermarket sub-woofer and amplifier to get it up and running properly. I can get the amp turned on and the sub working by powering them off the live input wire (the yellow one) however i would rather not do this for safety, electrical issues/problems, and blowing fuses. Anyone know where to find the proper connection for this.
