Question about Sony XM-1252GTR Car Audio Amplifier
How to disable protection mode
If the amp goes into "protect mode" immediately upon power up, it's most likely a short in the power/ground or speaker connections. If it operates normally for awhile and then goes into protect, it's most likely overheating.
In the first case, I'd suspect something in the wiring. Go here to troubleshoot the possible causes.
An amp will most often go into protection from overheating due to being operated at too low of an impedance load. Check the speaker specifications and wiring and make sure that the final impedance load matches the amps rating.
Hope this helps.
