stock size is 5.25", but any aftermarket will require some mods.
on my last 4runner i made and HDF plate/risers and used my 6.5" speakers from my tacoma. it was a pain in the ass.
what have ya'll done to fit a larger speaker in the back doors of a 3rd gen 4runner? should i just stick with 5.25"s?
i'm thinking MDF or plexi plate/riser with some metal trimming. this is what the innards look like.
