    • Excellent cable
Color: 25 Ft Black + 25 Ft Red Size: 4 AWG
This is real copper cable with flexible outer insulation. Have not installed this yet. But experience has demonstrated when having longer runs of DC current it is best to use copper. Also this comes from a small business here in the USA and the price was lower for copper cable. I am all about supporting small business here in the USA. ... show more

I’ve been working on cars for two decades, and these are hands-down the best copper cables I’ve used. Most brands these days cheat on the thickness, but these are true gauge. You can feel the quality immediately. What also really impressed me was the packaging. It’s clear this company takes massive pride in what they do. They didn't just throw them in a bag; they packed them with care. If you’re looking for high-quality copper and want to support a company that actually gives a damn about their product, buy these. 10/10. ... show more

    • Great product!!!
Color: 25 Ft Red Size: 4 AWG
For the price I wasn't expecting the quality to be that good but to my surprise it is really light and flexible and it's made in the USA. Great job TEMco for selling a great American product and a reasonable price.

    • Good Product for Car Audio
Color: 15 Ft Red Size: 4 AWG
I really appreciate this item. After buying another brand that claimed they had oxygen free copper the cables I owned melted from my sound system. When I switched to these it was obvious these were way more durable and could handle. higher power. After buying their 2 gauge wire for my subwoofer amplifier I knew I had to get these for another project. TEMCo is reliable and transparent which is why I give it 5 stars. ... show more
