Great 4ga

I bought 20' of the blue. This was to match. Very happy with the quality.

Great Value

Best price per foot out there. Very good quality, real OFC and not CCA. Nice looking covering.

NVX XW4 Wire

This Wire is a Copper Beast. The weight alone will confirm the difference between this and the Copper Clad Aluminum less expensive alternative. If aluminum wire or tinned wire is used, the gauges should be of an even larger size to compensate. ANY Power Drop will affect the Amp, and over time possibly a resistor or capacitor, A Dremel with a cut-off wheel and solder the Copper connector rather than attempting to crimp to give it a clean, solid appearance.

Great wire value

I chose NVX for all my wiring needs; from the silver tinned OFC for power, ground, and speaker wires, to the RCAs. After my research, these were the wires to get; and the pricing here is great.

Tru 4 AWG wire

No problems here. This stuff is a bit cheaper than the Rockford stuff so I gave it a chance. I bought 2 20' sections so I can customized my installation a little better. This is the quality you want in your car.
