Yep, got my first batch in last week. So far, I have only put in a 4x100 (in our Escalade)...so far, so good. They are very impressive from a construction and design standpoint.

One of the things I like about the 4 channel is the crossover...the high / low pass goes up to 5khz, and the subsonic can actually be used as another high pass, so you can run active seperates, and even mid pass if you want to.
