Good for rear fill
2006 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)
These are decent speakers for the money and make for nice real fill. I am using them in the rear pillars in my standard cab Silverado. They are amplified (by a channel in my PBR300X4) but I have them turned down quite a bit by the fader. Use a crossover to cut out the bass (what bass? these are 4x6's) and they'll do the job. Anything this small is not going to be good for anything but ambient sounds anyway- you'll have to rely on your bigger drivers for midbass and bass.
Pros: Power series is pretty tough and sound good. Good speaker for the money.
