My amp is in protect mode with no visible damage smoke or smell inside.
Hoping I could get some help trying to diagnose what bad.

Ill take some pics and post them up.
How do I check the transistors?
With ohm meter?
Im not sure what values to expect.

These amps have a problem with breaking the legs on various components clamped to the heatsink. They often cause intermittent problems initially, then cause components to fail. An intermittently broken connection on an FET can cause the amp to go into protect but not show any shorted components when checking.
In the attached image, you can see the copper near the solder connections on Q1. If copper is showing, the terminal is broken or in the process of breaking.

I turned the radio on one day and realized there wasnt any bass after a few songs. I never heard it go off though.
When My Hifonics Brutus amp went out it caught on fire basically and sounded like a welder n my trunk with sparks and all.

OK I heard that power side might not cause to protect only audio side, thats why I asked.
All of the components are susceptible to breaking. The power supply FETs may not cause it to go into protect but if one breaks because it was ignored, it can cause catastrophic failure of the amp. The damage can be so bad that the amp will be unrepairable.
This is vibration damage I guess?
The amp was in service for 7 years before this happened.
Ill check all the legs, then if I dont see anything Ill test them.'
Then Ill post back with my findings.
Thanks for the help!
