The perfect components for your Chevy or GMC! If you like your factory radio just fine but know there's still room to improve the audio in your car, then PowerBass' vehicle-specific speakers are a great way to step up the sound in select Chevrolet and GMC vehicles. This specially designed 6-1/2" component speaker system features woofers that are a perfect fit for your factory locations and bracketed tweeters that take the headache out of installation. PowerBass also makes things easier by equipping these speakers with factory-compatible wiring harnesses. Better quality materials means better sound! Say goodbye to flimsy factory woofers and whizzer cones. A sturdy yet sensitive injection-molded polypropylene woofer cone delivers the goods in the low frequencies while enduring the extreme temperatures of life in your car door. A 1" silk dome tweeter gives you smooth highs and all the detail you've been craving from your factory sound. PowerBass uses an inline crossover to ensure the tweeter isn't burdened with playing any low frequencies. These speakers will work great with your Chevy or GMC's radio, but you can get even better performance by powering them with up to 60 watts RMS from an outboard amplifier. Note: For specific compatibility please refer to the OE Series Fitment Guide found at Powerbass.
