This wiring kit does not include speaker wire or patch cables. You will need to purchase those separately, in order to complete your amplifier installation.
Your amp needs big power wires in order to deliver top performance to your sound system. Rockford Fosgate's RFK4 amplifier power wiring kit supplies everything you'll need to send power to amplifiers with fuse ratings of up to 100 amperes. Rockford Fosgate makes the 4-gauge cable from 100% pure crystal-oxygen free copper wire so you can count on maximum signal transfer.
