Rockville R4G12-BLUE 4 AWG 12 Ft Car Amp Power Wire, Blue

Please note that Audio savings audio engineers have tested this wire against 10 other brand names. We did all this research after getting complaints about certain other wires we used to carry. Many other brands did not measure to 4 gauge like our Rockville wire. They had thick insulation but they were short on the wire. This cable is standard American wire gauge thickness. This is another reason our conductivity is better than anything else at this price point. Other brands in the market place write 4 gauge, but cheat you on the thickness. We are honest about the thickness of our cables. We also tested resistance which is really the only thing that matters. Since Rockville wires are made with around 3 times as much copper as any other wire at this price point, these wires had a much better resistance rating which means they will transfer more power to your amps than the other brands.
