Power, Ground Wire - Thickness? 4awg?

[ekaJ]

I have a FLI 12" twin active - 800W RMS, 2000 Max. I bought a 4awg kit last year and that worked fine. Now the earth is too short in my new car and my RCA's were knackered, so I bought a new 4awg kit of ebay.

The new wires are smaller compared to my old ones, will it still be okay to use this new, thinner? wire as a ground, with the thicker power cable?

Alternatively, could I chop some of the old thick power cable off and use it as a ground?

is the copper that same diameter ? as it should be being both 4 awg kits

the ground cable should be the same size as the power cable

Just cut off some of your old thicker power cable to use, if you've got spare.

Thanks, what I have done

New wire was worryingly thin, cheap cheap!
