Radio from Aliexpress - purchase instead of the original radio

The car radio (Blaupunkt) smokes my speakers. A squeak appears and the speakers burnt.
On aliexpress you can buy a radio with an LCD display for PLN 200. How do they work? Or maybe it's better to add and buy with android?
Does anyone have experience with such radios?

You must clarify my friend, because no one knows how the radio with LCD display works for PLN 200 it's a bit like you would ask, how does Mercedes with climate work for 2,000 PLN from a dealer.

Hello.Troche did not write much about your radio, it burns the speakers because the power terminal is damaged (Blaupunkt) .New radio should not be a problem unless the parameters of the speakers do not correspond to what you will drive them.np for low power, inappropriate impendance. I write in general because in your description there is also not much to say about, e.g. car type, speakers installed, type of radio except that it is Blaupunkt.

Sure.
Blaupunkt has made you angry from looking at you.

As for tensions, I don't even know how to check them. He does such things sporadically, i.e. as needed.

My name is not Blaupunkt, but I'd love to snap your toes

Alternatively, look for the diagram from this radio. Throw in here, we will try to remedy. Excitation can also be caused by damage to the Zobel circuit, i.e. a resistor with a value of several ohms in series with the capacitor and the whole in parallel with the speaker.

The original radio is Blaupunkt Travelpilot DX170.

I am looking for a schematic.

That's why I'm asking if anyone has or had such a miracle and how does it work?

Hello.
You will probably have a problem with mechanical mounting on Good Morning - there are no pockets for them. Unless the original holes from the removed Blaupunk match.
Personally - I'd rather fix Blaupunkt than play Chinese CarAudio.
I installed 2 pcs. Vordon HT-869V2.
There is no revelation - it works, but the headunits that replaced the above-mentioned Vordon sounded much better (in Skoda Fabia I had 2 years Sony, in Renault Megane 2 years old Kenwood.
Installation problems due to the lack of dedicated pockets / half-frames (assembled about a year ago).
Greetings.

I'm for repair. But who will do this to me? I returned for repair in the city. The guest has very good reviews, but he did not, because he played for several days without a fault.
It also sounds like this to me, sometimes for a long time, and sometimes smokes 2 speakers a week. And always the left front.

Different nature of the load In your and guest's tests. Maybe a different supply voltage. You can see from the fact that the front smoke is probably the tweeter. I wonder if this "guy" connected it at all or just what was there by accident? I would check the other speakers in this channel if you were you. Maybe they have some shortcuts, i.e. a short circuit between the turns of the coil.

I have to replace all the speakers to check if maybe one is shorting?

Hello.
While the loudspeaker is installed in the door (left, front from the driver's side, most often used), the reason for this phenomenon may be a damaged wire (worn insulation, wire shorted to the car ground). I had this case.
greetings

I have already laid a new cable. And the speaker burned anyway.
I did not notice the specific situation when the radio smokes the speaker. A squeak appears and begins to smell.

This is due to tip excitation. The very reason for this excitation is not clear. I don't know how many speakers you have there, but you can swap them sides (on the radio itself) how it will burn the speakers on the other side, that means a problem on the radio.

Hello. How many times do you have to test? Do you burn all the speakers you have ?!

I put on the radio from Aliexpress. It plays nicely. Touchpad.
Only squeaks when increasing turnover. Will the interference filter, inserted on a 12V power supply, with the Allegro do the trick?
