Review on Scosche SAT69: Upgrade Your Toyota's Sound System with 6x9'' to 6.5''-6.75'' Adapter (Pair) by Mark Erandio

I used these to install a pair of 6" Infinity speakers in the front doors of a 2011 Toyota Tundra as the inserts that came with the speakers didn't fit into the 6x9 holes matched. The rear doors had 6-inch openings, so only minor speaker insert adjustments were required to install them. These adapters did the job and if I had to point out any issues it would be that I had to make my own screw hole on one side. Also please note that these are inserts ONLY and no screws are included. Generally 6" speakers will fit in a 6x9 hole - not ideal but can't complain.
