I ordered theses hoping they would help with just over all clarity of the factory Bose speakers. Well it worked, much tighter and distinct Bass and the highs are much clearer now. Only complaint is I REALLY wish they would have sent Self tapping screws instead of just regular screws. Having to Set 2 screws to tighten the panle down so its contoured to the door, then mark every hole, remove the 2 screws, pre-drill every hole, then put the pnl back up and install the screws was VERY annoying. The screws are much to long in my opinion as well. 1/4 in. Self tapping screws would have been perfect. There is no quality or detail skipped on these panels, I added some expandable weather stripping under the rear panels because of how the door is designed it leaves quite a bit of metal under the blocker plate and I didnt want that to possibly rattle, also a piece is needed between the window motor and door panel as it will rattle as the door flexes. I also wish they would have sent some flush plugs for the holes that are left open after removing the factory dust liner. Just seems like something that should be included to help seal the door off even more.
