Never had much thought till was seaching for HU and found if not almost all have standard 4x50W power, maybe some with MOSFET. I tot its like home AMP, maybe got 60W, 100W of power. When I say this, am thinking in the range of rm300-1000, be it 1 din or 2 din.

To help me decide better, what is the difference between each other since same watt of power. If close eye and setting all on normal, using same speakers, with HU all 4x50W, my assumption the sound should be the same ?

Sorry noob here coz I often see, individual say this model is good, that is clear sound but what exactly is good since they are all 4x50W. also I got an old sony 1 din, that one can view VCD with speakers and bazooka speakers and no external amp on my other car, it sounded better than my magnat 4 channel amp, alpine cross over, 6x9 alpine at the back but no external subwoofer.

Appreciate enligthen what sets each other apart if all are rated as 4x50W when one hears with only the ears and not the eyes
