Hi there, ive got this Car Amp and recently its stopped working, it powers on and allows pass through to other Subs with no issue.

There is a switch that says 0 or 180°

This switch has broken and now i get no output to the internal Sub.

I want to change the switch for a new one but this foam stuff is holding the board down, youll see in the pictures. What i need to know is how to prise the board away so i dont damage it and re-solder a new switch to fix the issue.

Any ideas how to lift it off so the board does not crack/break ?

or, if i cant lift the board off without breaking, how can i make a permenant bridge so that it is locked to 180°, which points will need soldering.

Any help, much appreciated.

 

Looks like the slide switch links point A to B in the 180 position, so i would solder the two points together.

Ive tried that and still no output to the in ternal Sub.

Though after a closer look at the board ive found this, looks like some resistors have popped. If they are popped, does anyone know what "k" they are and types for the two.

That resistor ia a 2.4K 1/2W , you can measure it to check it,.

Thanks, just got to find a way to get thje board off now so i can solder a new one on, and fit a new switch.

 

Maybe you can saw through the foam with a piece of string?
