basic stereo question

When I turn my stereo off, I get pops in the speakers.
My stuff is connected like this...
Computer > RME (interface) > Sub (with crossover) > Power Amp > Speakers
 
I turn on in this order...
Computer
RME
Sub
Power Amp
 
I turn off in the reverse order
Power Amp (small pop)
Sub (pop in the sub and the speakers (even though I turned off the amp as much as 30 seconds earlier)
RME (no pops)
Computer
 
I have also noticed that when my wife is busy flipping light switches in the house (she sometimes uses Clorox wipes on the phones, remotes and light switches), I can hear slight pops in my speakers.
 
Should I care about these slight pops? The have never been recorded to my knowledge. I've never been listening back to a tape and been able to isolate a pop that might have been from a light switch, so I'm guessing the RME is magically immune.
 
I just attempted to record the pop and failed. I started a recording and flipped the light switch and there was 0 identifyable pop in the wave form even though the sound came through the speakers. I tried with and without my external DBX compressor and in neither case was I able to record the pop.
 
My questions:
1. Do I worry about these regular pops hurting my speakers?
 a. I'm not prepared to leave the power on to avoid the pops, and as demonstrated, there would be pops through the speakers from normal household activity anyway.
2. Do I worry about my power supply to my equipment?
 
 
 Sorry if this post should have been in hardware. I don't know how to move it now that I've submitted it.

Turn your sub off before killing the power to the amp

The nice thing about a great amp is that will only fry speakers that truly aren't able to handle it's power output.
 
If you're lucky the amp will have protection for the amp should you fry a speaker and end up with a short instead of an open.
 
Frying tweeters is a right of passage. You can use the opportunity to learn how to use a crossover, either passive or active with a bi-amp strategy. I would imagine that most folks who have been there have done that. I think that I've fried more stuff with under powered amps than I have with the good stuff.

Any noises or pops you may be hearing after you have turned your power amp off are almost certainly due the the residual energy that has been stored in the electrolytic capacitors in the power supply. Although this energy may be still there for a little while, it should not be causing your speakers any harm as such. It usually dissipates fast because the capacitors are not being recharged.
 
What are the woofers doing when these pops occur? If they are not moving at all or very much then you really don't have anything to worry about. Any talk about frying speakers more than likely won't be an issue here.
 
It is things that can cause serious turn on thumps you have to be careful of. I had an older Kurzweil K2000 rack synth that sent out the most horrific of signals on turn on. Enough to move an active monitor woofer about 3 inches! (I don't have it now and the new Kurzweils are perfectly silent on switch on now)
 
A good rule of thumb is when turning on any gear connected to your system anywhere keep your monitor levels off/down or mute the mixer channels while you do it.
 
And Dave I have done something similar to a 50.000W PA live in front of a big audience and it was not pretty! (but don't we all have to have that happen at least once to us in our lives!)
