With all of the brand names, and non brand names that are out there today, which one deliveres the most bang for the buck. I am talking about amps and subs and highs. I just don't understand how one brand can sell an amp rated at some power level for $800 while another sells it for $200 with the same power rating. I understand that some amps produce more current than others, but come on... how much more current justifies paying the extra buck??? I am in the process of creating a system for a <$1500 budget, and am having a hard time differentiating between the name brand crap and the not so well known good stuff. Help me out here.
