We did a complete audio system overhaul in this Scion XB. We started with an Alpine infotainment system supplying audio to Kicker KS component speakers and a single 12″ Kicker CompVX subwoofer, powered by a Kicker 5-channel amplifier. To complete the package, we added sound deadener to keep the vehicle rattle-free with all sound pointed inward for maximum enjoyment.
