This is the only available aftermarket replacement sub woofer speaker for 2001-06 Wranglers. Specifically designed for the factory subwoofer center console, this exact fit speaker is simple to install and requires no modifications. Since replacement woofers were not available through the dealership parts network, speaker replacement was not an option. The factory speaker features special electrical characteristics, duel voice coils, shallow mounting depth and a unique bolt pattern, making it impossible to cross reference to another speaker. Our replacement woofer is an exact fit to the original and features several important upgrades. Our speaker surrounds are made from durable rubber and not original foam which is the most common cause of speaker failure. Foam dries out and disintegrates over a shorter period of time causing low output with buzzing and popping. Our speaker cones feature poly-coated paper that outlasts uncoated factory paper that's susceptible to moisture damage. The kit comes with detailed instructions and is truly plug and play.
