Oh wow, I have aluminum. It is clear that this is the product, I looked at various messages and needed something on the same day. I found the one I feel from Knu, it was copper but I bought the wrong one. If you're looking for a very cheap cable, then fine. Over the past 30 years I have come to appreciate the importance of cables for power, sound, safety and longevity. OFC is the only way out, but that would be fine at 4 gauge for a 200w amp for a couple of years depending on the weather you live in.
