Not the best.....
Crutchfield Customer Review (What's this?)
Got these in my 81 El Camino. First, Crutchfield told me the speakers I got would fit....They fit, but without the grills on! Had to modify that. The color was off. The part that wraps around door wasn't there. It just sits flat with no seal. The parking brake was easy to bend, but if you have a clutch, they won't work. I lucked out on that. They sound good, and was the only option without cutting holes in my doors, so they do work.
Pros: They kinda do what they are for.
Cons: Way too expensive, color was off, flabby, doesn't have support, have to bend e brake, 6 1/2's won't work with the grills. Since Qlogic has the patent on this product, they've got you the with price. At that price, ya think they would build them right.
