Kenwood KSC SW11 Compact Powered Enclosed Subwoofer Speaker Amplifier Bass Box | eBay
but less height

I'm visiting a local, high-end car stereo shop next week. I share their thoughts with the Forum. One question I'll be sure to ask is whether there a way to mount the Kenwood speaker under the dash on the passenger side at the top of the foot well. Given how low profile it is the unit may not affect legroom.
