I have a set of Infinity IL50s that look amazing, but one of them appears to have some damage to the RCA and line/speaker inputs. I had a friend remove the amp module and it looks like the board itself wasn't damaged, but we weren't sure whether just the switches/inputs could be replaced or if the whole module would still need to be replaced. Every module I found online needed repairs, and I'm not paying $175 for a broken one. Is it possible to replace individual switches, or should I just say screw it and get new speakers? Thanks in advance for helping this newbie!
