Great Kit

Kit comes with everything you need, including 3 sets of RCA cables that are twisted for less interference. The main fuse has a 300 amp fuse that probably weighs 5lbs, so very well made. Wire even the 4 gauge is extremely heavy for the size showing great quality of copper. The ends are pressed on the 0 gauge hot wire for the battery and for the ground 0 gauge as well, along with the ground 4 gauge wire which is about 6 ft long. The 4 gauge power is also about 6 feet long, the 0 gauge ground wire is about 3 ft long, so more than enough wire. I would highly recommend getting a fused Distribution block they are like $10 on Amazon, that way if you have an issue with an amp it will just blow like the 100 amp in the Distribution block because its going to almost take a direct short of the 0 gauge wire to pop that 300 amp fuse going to the battery that they supply.

Pros: Great wire, plenty enough wire, wire is nice and thick, great fuse block, heavy duty 0 gauge to dual 4 gauge adapters

Cons: No other fused other than 300 amp to the battery, figured for $370 would have everything, recommend getting a Fused Distribution Block for the Power wire, so if amp on one of the 4 gauge circuit has an issue it pops that, other wise the 4 gauge wire turns into a fuse for the 300 amp which could cause a fire.

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.

Rockford Fosgate RFK1 Amp Wiring Kit

Jonathan from Lehigh Acres, FL on 12/3/2017

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.
