Suggestions! Speakers for rear pillars in a 96 Silverado I just bought a new Jensen head unit and changed out the front speakers in my son's truck. I'd like to change the rear 6x4 pillar speakers also. Any recommendations? Crutchfield says I can use either a 6x4 or a 4 inch round speaker back there. I'd like the best bang for the buck of course, but want good sound. Should they be full range speakers or just woofers? The front door speakers I put in are full range. Thanks for any input!
