About the Rockford Fosgate RFK8

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 RFK8 amplifier power wiring kit supplies everything you'll need to send power to amplifiers with fuse ratings of up to 60 amperes. Rockford Fosgate makes the 8-gauge cable from 100% pure crystal-oxygen free copper wire so you can count on maximum signal transfer.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
great for supplying power to my amplifier, just needed to get a 50 amp fuse to replace the 60 amp fuse included [ Howbout  Sep 10, 2019 ]
A
Because Quinn told me to :) [ James E De  Jun 03, 2019 ]
A
It is designed as a unit and I don't have to do any engineer work to design it. Pretty much plug n play....literally. I expect a lot from this unit and I think it will deliver. Fosgate has a reputable name and if Crutchfield supports and believes in it.....as they promote it....so do I. [ Mark  May 01, 2019 ]

Payden sudjusted it as it would work with my factory replacement Pioneer sub would work well with it. I really think this is going to be the best fit for my FJ Cruise. Thank you Cruthfield for having the technical support you do. Payden did not try to sell me the moon and I appreciate that. I have been to some of the local audio shops here in Denver Colorado and they try to sell you systems that are well above $2000 that may be fine for some but that was way more then i wanted to spend.

I'd say it's water resistant but I wouldn't submerge it

Mine has been mounted under my hood for about 2 years and I've had no issues. I don't know that I would mount it completely in the weather but it does have a rubber o-ring where the holder screws together.
