2 questions already asked

Is the actual cutout 3.5" or is it for a 3.5" speaker with a 2.7" cutout?
[ Matther  Mar 13, 2019 ]

These came with the speakers I bought 2 years ago for a chevy truck I had. Not sure if I will answer the question for you but I will try. The plate covers the factory speaker square hole and the new speaker screws to the plate. I never had to cut the door panel or anything like that. It was a real easy and straightforward install.
[ Nicholas  Mar 18, 2019 ]
Can l install 4" speakers in the front door of my Chevy aveo with this product?
[ D.A.H  Jan 25, 2014 ]

Yes , I used these to install dash mounted speakers in my brother's Chevy truck.
[ GEORGE T  Jan 27, 2014 ]
I am not entirely sure but this is a universal bracket so is should have screw holes that line up, just like it did in my 88 chevy truck
[ andrew vargas  Jan 26, 2014 ]
