Help please. Replaced Sony DAVS300 with new receiver. Friend helped with installation. Unfortunately cut old speaker wires. Have "willed" old Sony to daughter and now can't re-connect the "Sony-only" connectors to the receiver (he cut the wires a might too short). Anyone tell me where to find such connectors (other than from Sony - $18.00/speaker wire!!!) Can I use an over the counter push pin type connector?? Thanks in advance. tc
