This mod may work on all 5th gen. Accords and is probably transferable to any other car as well.
Well if you have aftermarket speakers in your Accord then they may have a higher top mounting size than your stock ones, thus your OEM grills will not fit on top of them. This is a fix to that.
All you need to do is:
Go to the local hardware store and buy some longer screws, I bought 1 1/2 Inch screws, take your speaker grills to find the right Diameter for the screw. I used a metal screw that kind of strips its way into the plastic, worked fine, and my size was #8.
Also, in the hardware section, find Plastic or Nylon/Eurothane Risers, any material will do. Make sure the screw fits through the riser. I used 1 Inch.
Basically just put the riser in between your rear dash and the screw hole on the speaker grill, then run the screws from under your rear dash through them.
Keep in mind you may need larger risers, therefore longer screws.
It's easy. :thumbup:
