Hi! I have never been good in electronics so I would like to hear some opinions from you about a situation where I left my audio system in a room with a bunch of drunk guys and they started using it when I left the room for some time.Now I am worried that they did some damage to it.
It happened a few days ago that I had to leave these guys alone for about an hour. This set up consists of a mixer that sends the signal to the amplifier which has 4 speakers conected to it in a parallel way,so a cable with speakon connector runs into 1 speaker and from that speaker a cable goes to the 2nd one. When I left the room the mixer power was unplugged , the amp was turned off and the cable was disconnected from the first speaker (the other end still connected to the amp) on both channels.
These guys were drunk and they know absolutely nothing about electronics or amplifiers or speakers or what is safe to do with stuff like this and what is not so I am worried that they abused my stuff. While I was away they somehow managed to plug the cable back to the speakers , plug the power cord back to the mixer and they turned on the amplifier and turned up the volume.
When I got back after an hour they immediately turned it off. Unfortunately since that time I did not have a chance to test if it sounds different than before. but it really bothers me.
So my main queston is , how likely is it that they damaged something in the amp or the speakers when they plugged these together somehow and turned up the volume?
I don't really know how easy it is to damage these stuff or what means real danger to them. for example I can imagine a scenario where they turned on the amp and had no sound. Then they managed to plug in the mixer , turned it's volume to the max because they still had no sound. After that they found the cables hanging from the amp and tried to plug in the speakon to the speakers trying to fit it in place not knowing how to do it , turning it left to right with the volume still to the max till finally they locked it in place somehow. I don't know how they did it exactly cause noone told me but I'm sure it was something like that. Could they cause damage that way?
The thing that bothers me the most is that my amp has some problem with it's fan. 90% of the time when I power it on the fan does not spin nicely. It spins making a horrible crackling noise as if it was about to fall apart. I think it is because of dust mainly. When this happens I gently stop the fan for a sec with my hand and then let it spin again. I do this for a few times(2-4) and after that it spins normally pretty quietly. So it is almost certain that when they turned the amp on the fan acted badly again and they did not fix it like I do all the time. So they used it with the fan being unstable and I am worried that it does not cool the amp well enough this way. When I arrived I wanted to check for burnt smell but I could not because the guys smoked so much in that room.
So could you please give me your toughts about this whole situation? I don't know what type of protection is in these kind of amps and speakers if there is any at all. How likely is that they damaged something? And what signs of damage should I look for when I will have time to check my system? I know I am a noob in electronics but I really don't know if I am overreacting it or not so please don't be too harsh with me. And I'm sorry if my english is not too well I'm not a native speaker.
My devices are pretty basic stuff but I really love this system and it served me really well for many years now.
The amp is a Konig AMP10000-KN with 2x 500 W. this one here PA-AMP10000-KN - K
2 of the 4 speakers are Omnitronic DX1022 10" Passive 200/400W. this type Omnitronic DX1022 10" Passive DJ PA Speaker- 400 Watts.
The other two are a pair of a different type but they are also 200/400W speakers but with larger woofer. And the mixer is a behringer Xenyx 802 like this Behringer XENYX 802 Mixer.

How easy is it to damage my amplifier or speakers?
