I remember when I was just a youngsta.. my friends older brothers had kicker, Rockford fosgate, and lanzar.......... I know the other 2 aren't bad.. I still see them in every other car now but LANZAR.... I never really see them at all..... As a matter of fact.. NEVER! I see they have a new speaker... That claims to be 5k rms.... And a older model that lays claim of 3k rms. How much of that is true wattage??
