Good Buy

Curt from Manchester, NH on 2/21/2007

1988 Oldsmobile Cutlass Supreme Classic

Verified customer (What's this?)

I bough these adapters for my 1988 Olds Cutlass. The brackets work great. They took some effort to get them in (the metal bars needed to be bent around the speaker), but overall it was worth it.

bad fit

1985 Chevrolet Monte Carlo

Verified employee purchase (What's this?)

I was told this product would make alpine 6x9s fit the 4x10 opening in my '85 monte carlo. however the torsion bars that hold the trunk lid open still cause a clearance problem. ive heard the same deal with all GM G bodies. cutlass,regals,etc.
