Im repairing a Kicker CXA660.5 and I wanted to know what parts (FETs or push/pulls) are used for Q15/16 and Q501 and 502. I could not read the part numbers due to burn damage and I ordered some N channel FETs to try in it based on another Kicker amp I had but they are not working, Im getting very high current pulling and heat from the Q501/Q502 now. I assume I just got the wrong parts. The amp turned on before the repairs and the AB front/rear channels all work even though the protect light was on. I just needed to know the parts or if possible the type of parts (N or P channel FETs, or AB push/pull transistors NPN/PNP and the parameters that need to be met.
Ive also completed a few MRV alpines, older alpines, Orion old school amps, Deaf Bonce AAB and AAK and some Skar amps if anyone wants some information on those.
