Awesome installation aid
2005 Nissan Frontier
Crutchfield Customer Review (What's this?)
Bolts right up to factory mounting and allows you to fit aftermarket speakers into the space with minimal fuss. Allows for a clean factory appearing installaton.
Pros: Bolt up to factory mounting brackets. Allows clean fitment of aftermarket speakers.
Cons: Is made of a thin plastic but I have not noticed any rattling or vibration after the install.
