Will any amp wiring kit work with a car audio system if it comes with "everything"?

Question

I have 2 12" polk audio subwoofers with a Dual Electronics 600 watt amp

Answer 1

yes and no

it needs to be the correct size (gauge)

it may come with all of the wiring (for after market radio), like power and ground wires, the remote wire, and your RCA cables. It should come with an in-line fuse holder and fuse

sometimes you need extra wire connectors, cable ties, and you may need a "line output converter" if your radio does not have RCA preamp outputs
