This is an ALPINE subwoofer. Model number SWE-1200 I removed it today. I replaced the navigation system, but it was too much trouble to reinstall it, so I removed it. It has been confirmed to work. It will operate without any problems. The accessories are as shown in the photo. You can install and use it immediately after receiving it. The powered subwoofer SWE-1200 comes with a controller and wiring for high-quality sound. - Model Name: SWE-1200 - Type: Powered subwoofer - Accessories: Controller, complete wiring set thank you.
