Rockford Fosgate

Our take on the Rockford Fosgate RFK4

by Buck Pomerantz

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.

Highlights:

  • amplifier wiring kit
  • cables meet or exceed the American Wire Gauge specifications and requirements
  • 17 feet of 4-gauge power cable
  • 3 feet of 4-gauge ground cable
  • 20 feet of 18-gauge turn-on lead wire
  • AFS/MAXI fuse holder and 100-amp MAXI fuse
  • assortment of wire termination hardware and cable ties
  • warranty: 1 year
  • Our 60-day money-back guarantee

    Limited connection options

    Written By Jjkinsd, San Marcos, CA on Wednesday, May 16, 2012
    Crutchfield Customer Review (What's this?)
     
    Wire is great quality, provides power where you need it! Came with enough power and ground wire to wire a distribution block and two amps, so that's a plus!
    Pros:
    Quality
    Cons:
    Not enough crimp connectors for the #4 power and ground wire for one amp! In my opinion, at the price of this kit, you should be provided with more connection options as these can be hard to find around town. (I paid half price since I purchased with amp, thanks Crutchfield)

    Perfect kit for sound board

    Written By Keith, Marrero, LA on Saturday, February 04, 2012
    Crutchfield Customer Review (What's this?)
     
    Great package as wire and fuse was nothing like they used to put out with their amps. I ran it to a power distribution block to serve as the source power for all of my components. Everything was mounted to a piece of 1/2" MDF board so there was no need to run separate wiring for my subwoofer amp and sound processor.
    Pros:
    Nice, complete package, 100 amp fuse was perfect as I had 2 other components running off of the souce power it provided. Easy to handle wire that also went through a spare grommet in the firewall.
    Cons:
    It did not have a spare fuse; though you should not blow one anyway, it's still nice to have so you are not down should it blow for some reason.

    Nice Kit.

    Written By Kevin, Mesa, AZ. on Saturday, June 19, 2010
    Crutchfield Customer Review (What's this?)
     
    This is a nice kit and made it easy to wire in my new JL XD 600/6 amp. I was worried that the power and ground wires were a bit to short for my 2001 Chevy Silverado Z71 extended cab. However, there was plenty of wire for both the ground and power to wire in the amp under the back seat. The large gauge wire was plenty flexable to run around corners in the truck. The only downfall I can see it that I had to get a better firewall bushing to run the power wire to make sure it did not get nicked. I also replaced the included 100 amp fuse with a 60 amp fuse since JL recomended a 50 amp fuse if you run a single XD 600/6. Save your time running all over town getting wires and get this kit.
