just bought a 2007 Tahoe with the Bose radio but has an alpine Ina-900 Davd/navigation double din radio. With the bose radio system it sounded pretty good. Tonight I put in my JL 10w3 and JL 250/1 mono block amp and it balanced the sound out perfect. With it turned up loud it hits good and shakes the mirrors and the Bose does not seem to distort like my old truck did. Really happy with how it sounds. I'm going to build a new box for it since its in a box that is to small because I had to fit it in my pickup. I kind of want to get a second sub since I have the room for it.
