No need to swap wires to the player unless they are defective (if a mouse chewed through them). Never heard of a speaker causing a fire but i guess it's possible .
I've been a self proclaimed audiofile since the late 1960's. I've installed many a system for myself (currently have 3 big screen tv's in the house with 7.1 surround systems for each) and for friends. I've also replaced the radio's and speakers in every vehicle and boat I've ever owned and for friends. I've also upgraded amplifiers back in the day of transistors by installing larger bridge diodes, transistors, rectifiers etc. This doesn't make me an "expert" by any means, just experienced. If you get stuck feel free to message me and I'll be glad to try to assist. Good Luck!
