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

was damaged At first these guys thought it would be a good idea to roll up all the cables to fit in a smaller box. Apparently their packaging engineers never tried to remove the wires from the packaging. It took 10 minutes to detach the wire bird nest from the box. I had high hopes for this cable set. The video led me to believe that this is the best cable set for my amp. On the plus side, the speaker wire and power cords were very flexible and easy to route. The RCA cable was very high quality and the plugs fit my amp perfectly. On the other hand, one side of the fuse box was loose and since the back was weatherproof it was impossible to tighten. But the biggest disappointment was the power and ground cables. The power cord was routed from the front of the car to the rear, utilizing the full 17 feet. The problem was a significant voltage drop from the length of the cable. This caused my amp to be underpowered and shut down due to lack of 14V to the amp. I ripped out all 17 feet and replaced them with solid 4 AWG copper braid from Home Depot and it was like night and day. The thick blue power cord looks cool, but if it doesn't work, it's just not worth your hard-earned cash. I ended up using a fuse box, RCA cable and 5 feet of speaker wire. But I ripped out all the power and ground wires. Would return if I took the time to snag other stuff. Great video. Terrible power cord.
