Our take on the Blaupunkt GT Power 66.2C

Why listen to your old factory speakers when a nice upgrade is within reach? Blaupunkt combines its reputation for reliability with modern design in their GT Power Series speaker line.
This GT Power Series 66.2C component speaker system features 6-3/4" polypropylene woofer cones that deliver accurate, full-bodied sound. Mylar semi-dome tweeters reproduce the vocal and instrumental details smoothly and cleanly. The 3-ohm impedance safely draws a little more power from your car radio or amplifier. And the signature blue color offers a look as distinct as Blaupunkt's legacy sound.

Crutchfield makes it so easy to upgrade old car stereo from the golden oldies. I have a 96 Pathfinder and was expecting a whole day of installation. Took me only 2 hours to completely install front and rear speakers with the instructions they provided and the kits. I will buy from no other company !
