  • Its cool for a low wattage Big3 upgrade
I just installed this cable for my Big3 upgrade I am only running a 500W amp so this CCA cable should do fine...However I can appreciate that 1 side comes pre-crimped but whoever crimped it has no idea how to properly crimp wire...I cut there termination off and put my own on see pics of the difference...Take notes Amazon seller of this product ... show more

  • Quality
This wiring kit is as good as any other brand on the market at the fairest price. I definitely recommend it for any Big 3 upgrade.

  • Spend more, don’t buy.
Very cheaply made insulation, and stretches when engine is hot. Just spend more and get something better.
