Hi,
Appreciate again the "Ask Me".
Appreciate the "
FixYa" rating you have given me
here.
A request if I may, my being able to assist you is largely dependent on my standing (rating and raking) on the site. Since the Panasonic has been successfully dealt with, perhaps you can re-evaluate and rate the following as you see them fit:
Many thanks in advance. As to your current concern, the 400watt bridged amp:
- if the Panasonic was wired reversely, might it be possible that the sub amp was likewise wired reversely and therefore suffered similar electronic failure?
- most high power amps have a built-in DC to DC power supply other than the external 12VDC, these would often fail if reverse power is delivered even just once;
- since it is heating, then it is actively drawing power. that would mean that (if it is wired correctly), the SMPS (switch mode DC to DC power supply) might have a problem. Often culprits may include:
- capacitor;
- regulator;
- diode;
- or any of the other components.
Further diagnosis leading to a repair would require familiarity with electronic circuitry and components, use of a DVM and a soldering iron. Or perhaps you may again seek the assistance of whoever worked on the Panasonic.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
