Not cutting out holes in the rear deck!
1988 Chevrolet Caprice
Crutchfield Customer Review (What's this?)
I finally got rid of the old Delco speakers on my Caprice and added some new speakers with these brackets. I recommend buying a pair of Metra 72-4500 connectors if you don't want to add an amp to your car.
Pros: Easy installation. No need to modify the rear deck.
Cons: Might need an extra set of nuts on the either side of the bolts. My brackets were secured at an angle and needed to be level.
