I watched both videos of the NVX install - holy crap! I thought i could handle it, but after watching the second one for the D models (mine will be) I'm not so sure.
I got out of my test ride MS with the UHF and got into my Volt with the Bose system, and I've got to say, the Volt's Bose system sounded way better - on all ends of the spectrum - lows, mids, highs, and had a much better balance of sound through the vehicle (not just from the front like MS).
Zex, please be sure to cover whether you had the install done or did it yourself. I once thought I was pretty good at this stuff, but I'm second guessing my abilities after the videos . . . then again, I am not sure I would trust an installer either to not damage any of the interior panels or rubber seals/gaskets around the door and trunk seals!
