I obtained this item used. When I received it, I confirmed that sound was output from the FR and FL channels. However, after running it for a while, the power would turn off automatically. I left it as is for over a year due to the unknown cause, but I am listing it as junk to declutter. In preparation for listing, I was only able to confirm that it powers on, as shown in the photos. I have not confirmed anything further. I would appreciate it if those who can repair it or those who want it for parts would consider purchasing it. The only included accessory is the power cord. Thank you for looking.
