Bummer. There are a few others like it, though. Maybe the Kenwood one might fit? Or the Soundstream?etarasoff: [this in reference to the Pioneer TS-WH500A] ...that sounded like a perfect fix to me for some pain-free, moderate bass, but I chased down the dimensions and she won't fit: 14"x9.4"x3"--the 3" height fits tight floor to seat, but the 9.4" is a no go between the rails (the Kicker has the same dimensions). I don't know, headphones and a nice tube amp & let the passengers hum?
