I appreciate hearing from you that the Kappas were a significant improvement in sound over the factory speakers and that they fit easily. Have you heard any warnings about the 2 ohm speakers damaging the amp in the new head unit you'll be installing? A sales kid at a local chain audio store was saying to stear clear of the Kappas for this reason. I am thinking that actually the Kappa's lower impedence will provide more sound volume with the rather low powered amp of the head unit. Any other thoughts or experience is appreciated. It's great when you are doing exactly the same thing someone else has already done (or is doing). Are you also not planning on installing a sub? I don't listen to rap or hip-hop. I'm a classic rock guy; Led Zep, Badlands, Whitesnake, etc.
