Diff. between High Current and Reg. amps

Is one better then the other or does one serve a diff. purpose. Does on require more then the other this is what I would like to know. 

Give an example of an amp that you're referring to as a high current amp.Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Here are 2 examples       everyday a/b amp   50x2@4 100x2@2        most high current amps like the hc<--high current series of us amps and memphis hc50,hc100     50x2@4 100x2@2 200x2@1 100x1@4 200x2@2 400x2@1 800x1@1/22009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR

Okay, in laymen's terms (easy for me because that's what I am), there is no difference in installation of either class of amplifier.  A high current amp is only high current if it is being used at the lowest ohm loads, i.e., at or below 2 ohm mono or 1 ohm stereo.  You have to find out what power the amp will need and supply the proper wiring and alternator.  A high current amp will require exactly the same power and wiring as a typical A/B amp if both are run at a 4 ohm load.Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
