While there is no dispute OFC wire is superior over CCA wire, this is a nice kit and value when on a budget. This is a good wiring kit for your system. It comes with everything you need to install an amplifier or other high current load. The power out to the speakers of the amp is the result of what's driving the amp which is what the user must be aware of.

Best For Sub: soundbox 0 Gauge big 3 Kit

Buy on Amazon

We would, of course, be remiss if we didn't mention soundbox 0 gauge big 3 kit for regular usage. It’s the electrons that jump from atom to atom how current flows and current won’t flow without a potential difference. It’s great for smaller cars and ext cab trucks. The way you control the amplifier output is through the resistance or impedance you place on the speaker channel. It comes quick and looks ready to be installed.

The 0 gauge wire is HUGE, but it's not all insulation like some. It’s a channel for current to flow. A magnetic field is turned on and off rapidly to induce a higher voltage based on the principle of mutual duction, which in turn, creates an AC voltage because it is fly back. It is great for smaller cars and ext cab trucks.

• Speaker sensitivity is one watt at a distance of one meter
• Thick, flexible, high grade copper wire
• Great quality components, looks really nice once installed
