Quick Review:

Polk Audio's Signature Reference (SR) Series subwoofers were designed for performance and accuracy. They will give you the rich and powerful lows you love, while maintaining clarity and accuracy you need. The Polk Audio SR104 10″ car subwoofer is assembled from quality materials, including a lightweight but rigid cast aluminum basket, and a strong ABS plastic cone that gives incredible responsiveness. And a power thirsty handling rating of 700 watts RMS (1400 Peak), the SR104 surely will add the bump you're looking for to your stereo.
