Okay my car is not an Echo. It's a 2005 Scion xB but its on the same platform as Echo, but they dont have it on the pull down. I custom fiberglassed and molded this system into my xB this weekend with 2 Bazooka Tubes. Its powered by a generic 600 watt amp. Other notable things on my car are rims, lowering, tint, intake, and exhaust! Enjoy!
