This is a set of a KENWOOD CD/USB/iPod receiver I-K70V and a 160W subwoofer KSC-SW01. I have confirmed the operation by connecting a 12V power supply, speakers, antenna, subwoofer, and USB memory. AM/FM reception works normally. (It does not support Wide FM.) CD playback works normally. CDRs also work normally. I confirmed that MP3 files on a USB memory are played back normally. Note that 64GB USB memory was not recognized, so it seems to support up to 32GB. I confirmed that the rear speakers (L/R) also work normally. I confirmed the operation with the remote control. (Batteries are not included.) I don't have an iPod, so I couldn't confirm its operation. It does not have a Bluetooth unit, so it is not supported. Connecting to a car requires a vehicle-specific harness. Mounting screws are included. The subwoofer also works normally. When the remote cable is connected to the main unit, the power turns on and off in conjunction. I confirmed that the subwoofer volume works normally, but it vibrates when the volume is increased. It doesn't vibrate within my usage range, but those who play at high volumes may experience issues. Mounting brackets and screws are included. The USB memory shown in the photos, the RCA pin cables (red and white 2ch) connected to the subwoofer, and the antenna cable are for checking purposes and are not included. - Brand: KENWOOD - Model: Main unit I-K70V - Model: Subwoofer KSC-SW01 - Output: Main unit 50WX4, Subwoofer 150W - Accessories: Remote control, wiring kit, iPod connection cable, CR-ROM, instruction manual, box Thank you for viewing.
