Description of RWK4CU:

We challenge anyone to put this wire to a resistance test against any other wire on the market with the same gauge. If our cable does not meet or exceed any other cable, even if it costs 3 times more, we will be happy to call tag the item and refund you in full. Why are we so confident ? This cable is 100% copper. You cant have a cable with more than 100 % copper. So the only way a cable would out-perform this one is if it were being advertised as a 4 AWG but they are giving you more wire than advertised. No brands selling 100 % copper cables actually do this. We guarantee that this kit will compete with the most expensive amp kits on the market from Kicker, JL Audio, or any other top brands.
