Can you post the markings on the existing transistors? Also, if these are the output transistors, there shouldbe a complimentary one located close by Q24+Q34 maybe? Post those markings too.

the rem wire is for switched power from your head unit usually most after market stereos(head units) have an output for the rem wire.......if not use the power antenna wire from the back of the radio (usually blue or blue white) as for the input you need to use one or the other low or phono
Hope this helps..Good Luck!

Sounds like its a problem with over heating. open unit clean out all dust and dust bunnies wich compressed air. check that all fans are opperating. (fans on 6x100 amp units or thermal controled). If amp goes into protection prior to fans turning, there is your answer. the @ power supplies will have a green light on the output side. if the light in on power supply is good. or you can check that the output voltage is at 48Vdc on both units.
