I tried to use this in my car audio setup, but I switched to a different brand, so I'm selling it. The speaker cable is Mogami 3103, 3m long. This is unused. The power cable is of an unknown manufacturer, 4AWG. The red cable is about 5m, and the black cable is about 3.4m. This is also unused. These are leftovers. As a bonus, I'm including two copper plates that I was going to use for power expansion. They are unused and unopened.
