Nah, the Amplifiers yes, the other no. You can only run so many AMPS thru any given conductor/wire or device, connector/ switch. That connection was under engineered for about 35 AMPS. Which is a lot in 12 volt DC. Anything over that, and it over heats and causes Resistance, which in turn makes it get hotter and causes more resistance which gets hotter.......You get it?

This comes second nature to me, so it is harder to try to teach someone what it is I know. Just concentrate on a simple circuit first, then expand to more complex circuits. Like the horn circuit in the example I posted. It is best to understand an issue rather then just winging it the one time. AND maybe getting it work, but not understanding it.
