Hi Real novice here, so any help/advice much appreciated. I have replaced an old Lecson receiver with a Sony SRTLV 500 receiver. The leads between the subwoofer and the Lecson were connected at both ends by spring clips. The Sony now requires a banana plug connector, and I don't know how to go about getting the two open speaker wires into a banana plug connector. Sorry for my ignorance, but can any one help ?
