Summary: I bought these speakers for a friends '95 chevy truck. Stock speakers were 9.5 Ohms and wouldn't work very well on the new stereo system which I also installed. These 4 Ohm speakers were just the perfect size, power and Ohms for the new system. The installation was very straight forward and was a breeze. The sound that they produced were outstanding and well worth the price. Thanks for a good product!!
