The 3rd legs goes to a diode then the other side of the diode goes to the outputs..

C3526

So guessing its the driver for the outputs..

The KSC2690A may be a good sub.

Ok i put the 2690A in the amp..

Amp will power up after a fews secs it will start drawing excessive current then go into protection mode and then power back up and draw current then back in protection..


The amp will do this over and over..


Any ideas??

Ok im guessing the amp doesnt like the 2690A since the outputs will get red hot..


The orginal drivers says JE340...


Wondering if you have any ideas on what other transistor might work in the amp for right now so i can do some trouble shooting??
