These vehicles come from the factory with 4" and 8" speakers in each door. To install a new pair of component or coaxial speakers, a set of mounting plates are required. These plates are made from 1/2" MDF, precision cut by routers to the size of the factory speaker mounts. The mounting holes are predrilled, and counter-sunk into the wood. The hole for an aftermarket speaker is large enough to accommodate popular large frame 6.5" speakers. There is plenty of room above the hole to surface or flush mount a tweeter. The plates are primed and painted flat black to not draw attention through the factory grille.
