CDレシーバー — The Kenwood U737 is a compact single-DIN CD receiver from the JDM market that punches well above its footprint. Beyond standard CD playback it reads MP3, WMA, and AAC files from both disc and USB, useful flexibility for a modern install. The preamp output hits 2,500 mV, more than enough to run an aftermarket amp properly, and rated power is a solid 30 W × 4. TLDR: Has a bunch of sick cars on it ripping it around while you listen to music. Bluetooth is tested and included. Amplifier has been tested successfully. CD has been tested successfully. Harness Included.
