i would recommend putting a clamp from stack to the top of the bed, it will stop alot of the window vibration

I got 2 6inchers and it doesn't vibrate too bad on acceleration but once the tc locks up at 50mph it vibrates pretty good. Guess that's why my girlfriend likes the back seat.

That is not actually true, in all cases. I have a clamp holding my stack on the bed and it doesn't really help at all. The thing that will help the rattle is a Muffler and a Resonator. Dynamiting the roof should help as well from what I have seen.

i had the same problem when i had dual stacks in my truck and when i clamped them to the bed the vibration was pretty much gone, but they were alot higher above my cab, the new one is just shy of the top. that might have something to do with it:confused013:
