Help selecting AC power adapter for DC car monitor
Assuming a typo and you meant the Pyle PLHR78W, I find that it consumes 8Watts, which would be 0.67 Amperes at 12Volts.  Your 2Amp, 12Volt power supply should be fine.

I can't find PLHRQD8W anywhere, which is why I assume your voice type software mangled it.  Even if not, the power consumption should be comparable - the power consumption seems to be coded into the model number, and both say 8W.
