Why would my 2500 soundstream Rub1 amp keep going into protection mode

Take a look inside it could possibly be a/some capacitor/s. If it is replace more than just one because they can also be going bad. This is a cheap fix they cost less than one or two dollars a piece.(if this is the problem)

Soundstream pca2000d started smoking on me what do you think is wrong

well. if it doesn't function after smoking, then it needs to go to a GOOD technician. ( if one is available to you) if not then send it to soundstream. if this was not a good amp , I would advise getting rid of an amp that smoked, however soundstream is a good brand and deserves another chance. (always depending on the cost of repairs)
hope this helps.

Power to rubicon 404 no sound 4 channels of 2-way high pass

Check RCA,s at the back of the head deck, make sure sub is set to low bass frequency, make sure gain is turned up on the amp and head deck has subwoofer enabled and bass on. If you are powering speakers make sure the balance on the head deck is set to 0. Make sure it's wired up properly.

My first guess is IC 702 in the crt drive circuit. You could open the back and unplug the "C" board from the back of the crt and then power it on. If the set comes up and you have good audio that will isolate the problem.
If IC 702 is the problem you'll have a couple of other things to check, R533 .47ohm 1/4 watt fusible resistor and C541 22uf 100v both on the "A" board because they tend to stress when IC 702 begins to leak. Replacing IC 702 and not the resistor and cap could cause 702 to fail again.
If IC 702 is not the problem then it could be the flyback.
Hope this helps!
