I will be installing subwoofers into my 2003 Elantra GT 5-door. How many feet of power wire and RCA should I have. I have had these subwoofers installed on another car, so a kit has already been bought before, so I don't want to buy a kit that will have stuff I don't need. Plus I am sure buying the replacement parts will be much cheaper.

Thanks

about 17 is enough

yep....clarion is right! That is the length I used.
