Amp for Harley Davidson Bike

[caraudioguy2100]

1 channel doesn’t have any output .

When I opened it up I noticed what I believe to be a capacitor is blown open .

when this cap blows is it usually due to one of the ic’s going bad ?

Any Thoughts

This is likely to be a resistor, not a capacitor. Anyway, your unit most probably is a class D amplifier. Servicing and repairing is hard, especially without any schematics.

Best regards!

Doesn't the amp have 4 identical circuits that would allow you to find the value from one of the 3 remaining circuits?

 

[Kay Pirinha]

Anyway, the question of why this resistor was popping would remain unsolved...

Best regards!

 

[Perry Babin]

We don't know for certain what it is, resistor or capacitor.

Then we need to know how it's being used in the circuit.

The failure could be random or due to other defective components.

I will remove the defective part and the corresponding part from another channel to check it to see if it’s a resistor or capacitor

The IC looks sort of like this. There may be something in this datasheet to help.

I saw the title and I'm thinking "Why?? Aren't they loud enough?"

That datasheet looks pretty likely. These two networks appear to be identical RC rail decouplers? In which case your amp chip has left this Earthly plane ":^)

Unless it´s a speaker or wiring problem, it´s usually beyond users (and many techs) reach.
Sigh.
