I use all copper terminals from Lowes...work great and are thicker and tougher than that gold plated crap made by big name brands I'd rather have copper terminals than gold or platinum plated crap. I just need some big a$$ crimps for em....now I just use my big hammer and pound the crap out of the terminal
only the first time. haha then the next time i install the same cd player all i gotta do is get the connectors, but i see what you mean by more resistance though.
