The poly woofer and butyl rubber surround give you solid bass.
Rockford Fosgate innovations
Take a closer look and you'll notice a couple of cool innovations. Rockford Fosgate uses a new technique to attach the surround to the cone that yields up to 25% more cone area, for fuller sound and stronger performance. They build the crossover into the speaker frame so you don't have to find an area to mount a separate box. The slots around the frame eliminate the need to redrill screw holes when the factory holes are just a little bit off. Grilles are included.
Note: The oversized terminals on these speakers won't connect to a Crutchfield wiring harness. We recommend that you buy a 10-pack of female quick slides that you can splice onto our harness.
