correct order of connecting a preamplifier, amplifier, and speakers


  Sorry, guys, not such a good question. What is the correct order of connecting the preamplifier to the amplifier to the speakers before I power everything up? I should know the answer to this question, but just simply have forgotten. Obviously, I am concerned about blowing a tweeter or something. Big thanks for your replies.

Never thought about this before, always just assumed, I know, that if power was off to all equipment that there was no real order or wrong way. What is the thinking behind the sequence already stated by @noromance ?
Yes, the order of connection doesn't matter at all. The order of powering the components up is all that matters.
I wasn't certain what the OP meant so I listed the connection order in case they weren't sure. Not everyone is technical.
If not powered up, the connection order doesn’t matter at all. When all is connected, power-up; start at source(s) first, then preamp, then power amp(s).
