Bring your favorite songs to life in the car with the JBL GX502. You can do so even when you don't have an expensive amplifier, because these 2 speakers pull extra power out of your car radio, thanks to the low impedance. Place the speakers in your door or on the rear shelf, and enjoy powerful bass performances from the woofer. This driver has an extra large cone that can deliver deep tones just like a larger speaker would. In combination with the clear vocal and melody lines from the tweeter, it seems like a band or DJ is performing on your backseat.
