Well, i was looking through all of my car audio papers (manuals, etc.) and came upon a verification certificate for my Alpine MRD-M501 amp. I got to looking at it and saw that the specs had it listed at 550w and the actual had it at 612.5w, tested at 14.4v (hand written in). I know Alpine is underrated, but i didnt think it was by this much, thats 62.5w! Do any of yall have this card and can post the specification vs the actual? I'd like to get an idea of how much underrated Alpine is. Plus, it could help others in making amp decisions, maybe.
