Hi Ant, yesterday I finished installing the trunk pack and the door kits in my car. I`m using CDT HD-62 components with a 8W7 in the hatch, and I`ve never said this before which gives more credence to how true this is: I cannot believe your product. I went from having doors and the liftgate rattling from just driving down the road, to complete dead silence.The car is a Civic Si, and as such, it`s got a pretty high strung engine which can get pretty tiring to listen to after a while, but now, the noise I would say has dropped by at least 40%. When the sub is going, the gate feels solid and all you have is clean, smooth bass. The doors are about as dead as they can be without being made from solid wood and when you close the doors, you`d think you`re getting out of a BMW instead of a 2800lb Honda Civic.
So basically, thanks for making an outstanding product, and I`m recommending it to everyone I know!
