Gold Plated Connectors

In industry, gold is used for connections that will be exposed to harsh conditions. It's almost completely inert, and won't oxidize or corrode, so it's perfect for places like under your hood. In terms of resistance, silver is the best you can get, but in addition to it's propensity for oxidizing (Ag20 is an insulator), the benefit over gold is too small to be of consequence in car audio. Nickel is a nice hard, durable plating for connections, and unless you're planning to soak it regularly, don't worry about it. The important thing for any connection is to make it clean and gas-tight. That means proper crimps (cold welds actually, if done right) and correctly tightened connections (no loose screws). Aside from galvanic reactions (copper on iron is bad, as is gold on aluminium) it's pretty simple. -daveThis is not a sig. This is a duck. Quack.
