I purchased these online and installed them in my 2006 corolla. They replaced the kappa 60.9cs. I was not really impressed by them, I love the infinity sound and I highly recommend the kappa 60.9 cs. The tweeter on the perfects were to quiet and the components sounded like one big tweeter when you really turned them up. I hightly recommend kappa 60.9cs they have excellent sq and the tweeter is perfect!
