It's Copper Wire

Tommy from Lafayette, IN on 4/7/2018

Always pretty good quality from Rockford Fosgate when it comes to power wires. Usually thicker than rated. Wire is way over priced though. Using the pure crystal ofc ups the price more, but adds no benefit. The only argument audiophiles have had for pure crystal copper is it's better for signal wires. As far as I know this has yet to be proven but this is power wire no signal degradation to worry about. You can grab 20 feet of 2/0 AWG welding wire for $50-$80 and grab the rest at a big box hardware store or something for pennies on the dollar and never notice a difference. Save your money for the parts of your system that matter.

Pros: It does what it says it does.

Cons: Way over priced.

Needed this wiring set for my 2500 Rockford Fosgate amp. Well packaged and every item to self install was present.

Pros: Perfect for 2500watt amps and up, well packaged.

Cons: No signal kit provided, just power and ground wiring. Only way to get the full kit is to purchase this kit but for dual amp.
