Upgrade your speakers in your MkIV Supra with a simple bolt-in solution!

We can make these just about any size up to 6.5" All we need to know is the hole size you need, and we will make it that size! Right now, the base hole size is 4.75". Please specify if you have a different size in mind, either the size of the speaker or the size of hole needed.

These are made from 1/4" thick birch wood, and are solid with no fitment issues! Price includes one for each side (left and right)
