Installed my new kenwood KSC-SW1 powered subwoofer today and you wouldn't believe the improvement over the mid oem system. I have the 6 cd changer non rf system and this powered sub exceeded my expectations by 1000%. This tiny 150 watt 6.5" powered subwoofer fits perfectly in the optional tool tray under the rear seat on the passenger side. If you're lacking that extra bass you missed and don't want over-powering butt rattling thump, this is it.
