Review on 🔌 Rockville RWK4CU: Premium 4 AWG Gauge 100% Copper Complete Amp Installation Wire Kit OFC - Unmatched Quality and Performance by Shaun Robinson

: January 2020 After using this kit for a while it's holding up really well, getting a good stable stream for mine Amplifier and DSP, I keep seeing this is NOT OFC with silver threads on a black wire, THIS IS TIN PLATED COPPER, this is done to prevent corrosion as most of the time people run on the ground to the car frame underneath Auto, look at the tinned copper and why it is used. The only mistake in the description is the number of strands, they say 1862 but actually 1911 (7x7x39) and that's a good thing. Be sure to bring some sleeves and some good 4AWG crimp wire lugs and some good double wall heat shrink for a great fit and perfect connection. blow out. The cable is indeed 4awg OFC, very flexible, with a thick jacket, mesh jacket mainstays on the power cable, adds extra protection under the jacket. The fuse box is very well made. The speaker cable is flat so it's nice to run under the carpet as there are no cracks. The ground wire is tinned, oxygen-free copper. This requires large supports as it helps prevent corrosion. Good selection of gaskets, crimp connectors and covers, even cable ties are added. All in all this is a very good set at a reasonable price. When running at two amps and 1500 watts RMS of system power, the cables don't get hot and don't have any weird drops in performance.
