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

I installed the system myself and thought I had a ground loop problem because it hummed when the headlights were turned on. Good after 2 different stores, total 8 hours troubleshooting cost (+$600). The problem turned out to be an RCA cable. BOTH kits I bought had bad cables. While the fuses and cables are good, I can't give this product a good review when it's cost me so damn much money. Don't skimp on your car stereo, lesson learned.
