I explain, the amplified speaker did not light at all because the fuse was damaged and the two output transistors replaced them and the speaker turned on but only the horn was heard and the driver did not, then I soldered the positive horn cable and put it on the driver's output track and there was no sound from there I changed a capacitor from the driver's output and now neither of them is heard and I don't know what happened and I told myself I will change the capacitor that I had before and still don't hear anything and I I followed the audio signal with a small amplifier heard from the input to the
s
I found the fault was that a dirt track that led to the speaker's negative was broken and could be seen because it was covered by a large capacitor.
Well I managed to sound the horn now I measured the base of the output and one has -0,557 to 0,562 and the other 0,555 to 0,561 asked
Is it correct with that variation?
because it warms the trasistores too much when it sounds like I should do to lower the temperature

Orlan what voltage is between base and base of the transistors (place red tip on one base and black tip on the other base), there should be between 1.3v 1.5v or so.
between base and base is 1.15 but let's put it to 1.2, I think it's correct
But I realized that the horn has 1 ohm and I think that is why it is heated now the speaker does not say how many ohms it is but these speakers I think are 4 or 8 ohms.
Strain an 8 ohm speaker at 500w. The heating is by the short coil of the speaker. Another way of knowing is if the speaker has output for another speaker; if so, then the speaker is 8 ohms if not 4 ohms.
