Jump start your ride with the 1000W 15" subwoofer from Kicker. The sub is ribbed with Santoprene around the edges for a deep bass that will literally rock the car alarms in the neighborhood. Sounds are clear, even at high volumes thanks to the constant-contact, black bracing on the woofer cone. This speaker is designed for maximum performance with a dual voice coil and 2 ohms of resistance. Turn up the volume and let the good times roll.
