I used to think like you man lol. Wait till you try a sundown, dc, dd, skar, b2, flatlyne, incriminator amp. I thought power was just power but shiiiit i didnt know how worlds apart these amps really were from budget brands like hifonics, soundstream etc. This is comming from a guy that ran lots of hifonics, sound stream and ppi with great electricals
budget brands have their place and is fine for budget use, but if you can get a good deal used for quality, its definitely worth every penny. literally louder, better sounding less current draw and overall clean heavy pounding power. Yes there is a HUGE sound difference.
