These are designed to take OEM toyota speaker pods and convert them to allow a more modern speak to be fitted in its place. Alot of the toyota designs use a 3 screw layout where all aftermarket of the same size are 4 bolt.
These simple plates convert between the 2.
No cutting required.
Simple screw in
On models where the OEM speaker box is vented like the Supra after testing I found that if you block the vent in the OEM boxes you get a much more punchy bass and richer sound. So I've designed these from 7mm 316 Stainless Steel engraved with our company badge. Simple Push Fit although a bead of silicone for best air tight results.
