Rockford Fosgate Power BD1000.1 - works, produces sound but...
There is something like a switching noise at the output speaker terminals (can be heard really well even with a subwoofer mounted in the trunk).
Another concern is Q13, Q14, Q15 and Q16 are getting extremely hot in a very short time. Is that an indication of an issue or it is "factory" like that ? I can replace the heatsinks and use a bigger ones but that would not resolve anything if there is an actual issue.
Any guides ?

The regulators normally run hot.
Switching noise? like a high-frequency whine?
Is the output filter at the speaker terminals OK?
If you parallel another filter cap across the speaker terminals, does the noise change?
