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, and it's unused. The power cable is from an unknown manufacturer, 4AWG, red is about 5m, and black 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.
