The 05 is pretty sick! I own the NISMO 4x4 with all the bells and whistles... I think the only thing I don't like about it is the fact that the KC doesn't come with the Fosgate Package... I have the head unit, doesn't say Rockford Fosgate, but it's the same thing..
But there just isn't an option for the Subs... Guess I'm going to have to custom build my own box and I'm definitely keeping the head unit... that thing didn't skip once the entire time I was rock crawling at Barnwell Mountain, TX.
