kruger & matz km620t11 - kruger & matz km620t11 loudspeakers wheeze

Welcome. I am new here and I add a post by phone so I apologize for any shortcomings: p
Well, I have a problem with my kruger & matz km620t11 set.
I installed the loudspeakers on the soundproofed door and everything sounded nice, until after some time I fired the car to leave the garage, the tweeters in the set began to grunt as the radio was turned in half, when the volume was down the radio could not be heard wheezing, maybe I mistook the cables on the crossover + from -? Such swapping of cables can have such effects? What are your guesses? Thank you in advance for your help

And are the speakers really guilty? Does the radio also go off after connecting other speakers?

As previously played and now does not play, these are two options in my opinion (as it played for a long time and not just 5 minutes ). Or you just burned the tweeters. Do you have any raises, loud etc. on? The second option is some short circuit in the cables. Review everything carefully and you may find some worn cable or other irregularities. Swapping + and - in tweeters will not burn them will only reverse the polarization. Very often it is done so that the set sounds better around the crossover network. All in all, there is the possibility that these tweeters are simply very weak and therefore wheezing

A few opinions from the prices:
"At first, I was not impressed by the padak's thought worse than my old factory ones. Something creaked. It turned out that something was mixed up at the crossover. It got short. After the corrections were made, the speakers started playing perfectly. They play good muze for this better money you won't find peacefully they can compete with high-end speakers. I RECOMMEND "

"I bought this set and thought that for the money you could expect just working equipment. In the first set I got both tweeters did not work. One had broken soldering and the other just did not work. Pure case I thought but after replacing the other set that was to be the tweeterm problem is working again, namely the game is not clean. If everything was okay the first time, I would be happy with the equipment and, above all, how it plays. "

So not only you have such a problem.

PS. People write where you are from because it may turn out that there is someone smarter in your area who could look at it. This comment is not only about the founder of this topic, but many other people.

I have a Sony CDX-G1101U radio and I have "mega bass" enabled
The speakers sounded nice for about 15 minutes
I will check the cables but I think they should be good because all new copper and not the trash what they give in the set
Oh, I forgot to say that I exchanged cables in tweeters for other ones because the original ones were too short

Added after 29 [minutes]:

I checked again and the tweeters wheeze when there is bass, it looks like the tweeters want to bring out the bass

Added after 1 [hours] 39 [minutes]:

I checked again, all front and midrange speakers hiss in front and in addition the rear speakers also hiss (original rear), but when the radio switches to the rear only it plays normally, and when it switches to the front it again hacks

The short circuit is somewhere. Look through the cables. Disconnect the crossovers for a moment and connect only the woofers at the front and you'll know if it's on the radio - crossover or crossover - speakers line. Sometimes, without crossover, do not connect tweeters because you will burn them. You can also disconnect all speakers in turn. If you unplug a loudspeaker and it stops stopping, you will know where to look. And does it wheeze only when the car is on or not?

It's best to give photos of how it's connected. From the radio, to the crossovers, to the speakers.

Mega bass must be turned off.

I checked everything again and it turned out that one cable was short-circuited.
Thank you all for your help and best regards!
