O yeah.....These bad boys are sweet and crisssspy. I installed these in a set of old Kenwood vintage Home audio speakers replacing the old original ones. Yes you can say overkill but man they are nice and I don't have to fret about blowing theses things. The crossover built into the kenwood speakers are working great and what more can I say. There heavy and well built like I expected JBL to be.
