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.
Perfect. Good quality wire kit.

Perfect. Good quality wire kit.
This kit must have been designed for sub compacts, in any case the ground wire is too short for any vehicle. The power cable is way too short for my 2019 Ford F-150 supercrew. I had to purchase longer cables, both power and ground to complete the job. The only thing I could salvage from the kit was the fuse assembly. The only reason this got two stars is the cable is of good quality.
Cons: Cables are too short.
Worked out perfect for my 2017 ram 2500. Had enough power lead with maybe a foot to spare. Wish it came with some split wire loom to shield from heat in the engine bay but no big deal to pick up at auto zone. I also played it safe and put some heat shrink on the connectors plus it looks nicer. Over all good product and great price.
Pros: Good price and quality
Handy dandy with everything you need to add power to an amp.
Great quality electrical wire. You can actually feel the difference vs the other competitors wires.
High quality cables. lengths are more than enough for a quad cab.
Pros: length and quality of wires.
Cons: no component cables.
Simple and easy to run. Quality wires. Used it to with up a t400x2ad amp.
Everything went together quite nicely and now it works perfectly.
SUPERB combo of amp plus speaker!!! Easy to install and Crutchfield was there winwalk me through every step. Thanks guys!!!
Really liked the quality of this product. I had purchased the same thing but a different brand previously and this one far exceeds it in quality.
Worked good. Wish the ground wire was longer. Better to run both cables directly to the battery when installing on a motorcycle.
Like the kit but it's just a power kit. Where's the rca cable ??
Cons: Lacking rca cable.
Cons: Not spectacular!
Plug and play and great quality wire.
Pros: Clean good looking kit
Everything about this kit was exactly what I needed to install my amp and subwoofer. I wish the red power cable was maybe an INCH longer? But everything worked the way it was advertised to.
Pros: Great quality, sturdy manufacturing
Cons: Could be a wee bit longer
Good amp kit
Pros: Good quality
Everything I needed and then some. It even has a few assorted lugs just in case you have to grab a different size ground bolt than the one that comes attached to the black wire
Pros: Everything you need
High quality content. Definitely worth the extra money.
Works well and wire is not overwhelmingly thick so it was easy to hide
Great product. Came pre terminated on the terminal and chassis ground end, came with tie wraps and so far I have no complaints on the quality. I would buy again.
Pros: Complete kit, pre terminated
Great Kit! Not much else to say other than don't forget to order speaker wire and RCA cables.
Overall got the job done. Very easy to use for your sub. To be honest a bit pricey looking at other websites for kits like these. But it got the job done.
Pros: Everything comes with it.
Cons: A bit Pricey.
Great product for the money. Quality you would expect from Rockford Fosgate. Remember that this DOES NOT include RCA cables or speaker wire, those have to be ordered separately.
Pros: Everything you need to wire an amp
Great set of wires. Everything was great quality except for the zip ties - may want to go buy your own.
Pros: Price - especially when you buy Rockford Fosgate products you get a discount.
Very good quality, looks good and works well. Very happy with my purchase!
Power cord a lil short and no rcas.
Pros: It's ok
Cons: Power wire a lil short and no rcas
The length of wire was not sufficient to reach from the battery to the trunk of my Highlander. The length of grounding wire was not sufficient as well. I had my car in pieces all over my driveway and needed to put it all back together with an incomplete installation. Very Disappointed. I had it professionally installed the next day.
Pros: perfect length of wire for a Honda CIvic
Cons: Wires not long enough for a proper install in large SUV
This kit was already crimped and assembled once I received it! 8-gauge wire is usually hard to crimp but Crutchfield took care of it for me! They even connected the receiver wire to my wiring harness!
Pros: Pre-assembled Power cable perfect length for vehicle
Cons: Ground cable was a little short
Only other thing needed to wire your RockfordFosgate amp is a little time, knowledge, and patience.
Pros: Everything needed mfg suggests (except RCA) and when purchased with amp RockfordFosgate extends warranty by 1 year!
Cons: The 17ft length was barely enough to go from battery to trunk in 07 Grand Prix.
Great quality for the money.
It was suggested that I purchase this kit to install my subwoofer in my car and I am glad I did. This kit comes with all the needed power cables to install a powered sub in your car. The kit seems to be of high quality and made my install very easy, I would recommend this kit to anyone .
Pros: High quality wire and connectors in this kit.
Cons: Price is a little more than other kits but this has very heavy duty wire included over other brands.
Perfect best 8 gauge wire money can buy
Works great. No complaints.
Pros: Simple install
Professional cable and fuse, with lots of length to spare.
Perfect for installing sub with built in amp great quality
Pros: Quality product and great service
Just what we needed to complete the installation!!! worked Great!!!
This is a great kit for the money ! All the parts are quality made and look great.
Pros: Quality parts, looks great
This is all you need to get an amp or powered sub gong!
Good quality materials and works perfectly.
Installed this wiring into my F150 supercab and had enough cable to run it towards the backseats of my subwoffer. Easy to install kit.
Pros: Great quality and price.
Crutchfield knows exactly what to send to simplify your installation efforts. Great product to go with my powered subwoofer.
Pros: Contains the necessary installation components needed to install my powe red subwoofer. It was so easy to install.
This package looks good but I noticed looks can be deceiving.
Pros: Looks/feels like quality material.
Cons: Some benefit of having quality, many stranded wire is lost when the wire inserted at the factory is just jammed. Into the fuse holder and crimped down. It weakens the connection and will fail sooner.
Originally, I thought that the 8-gauge battery cable provided in the Rockford Fosgate RFK8 wiring kit would be big-time overkill, but now I'm glad we chose it. The kit may be a little expensive, but trying to piece together and assemble all of these components and connectors separately would be a nightmare. The cable is soft and easy to route through the cabin. We were able to run the red positive cable from the battery of our sub-compact hatchback to the cargo area where our powered sub was located with less than 2-feet of wire to spare, so beware of the cable's length. The 3-foot gray ground wire was also a snug fit. We found a good spot to mount the inline fuse holder on the firewall, just behind the battery - no problems there. We used the included turn-on lead wire, running it between the sub and an accessory lead wire that we found in the driver's foot well, to turn our sub on whenever the car is on. My only regret about this kit was that it didn't include speaker wire for use in making high-level speaker input connections. I realize that not everyone needs speaker wire, but Rockford Fosgate does offer a different version of this kit that includes low-level RCA cables - so why not make a version that includes high-level speaker wire too? Anyway, I'm very glad that I bought this kit. And at half-off the price with the purchase of a sub, it's really a bargain. I would highly recommend this wiring kit for anyone installing an amp or powered su
Pros: Almost everything you need in one package.
Cons: "Almost" everything you need in one package.
Good product, easy to install and look clean.
This kit was exactly what I need to replace my old amp kit. The length was perfect for my 2010 Chevy Avalanche. I even notice my subs hitting harder then before. The quality is great. I recommend this product . I rate this product 5 stars!
Pros: More juice to amp resulting in way better performance from my subwoofers.
Great wire, great quality, easy to strip and install.
Pros: good stuff.
good kit. cables were long enough to reach amp in trunk, but the provided connectors were too wide for the amp I purchased. so I had to go to a local stereo shop to get connectors that would work.
Pros: good kit. cables were long enough for my job
Cons: connectors provided were too wide for amp that was purchased
The components that came with the wiring kit where made of quality products but did not include RCA cables so i had to make an extra trip to get a set, so i would recommend buying a kit that includes everything you need.
Pros: Quality Product
Cons: Missing RCA cables
High end kit at a decent price. Only problem is the kit doesn't come with RCA patch cables (WHY?). I didn't notice this and had to buy some inferior ones locally to continue my install.
Pros: High end
Cons: No RCA's.
Excellent quality cable that is extremely thick and heavy duty. It was plenty long enough to run from front to back of my Hummer. Great fuse enclosure.
Pros: Excellent quality Thick protective coating Great fuse enclosure and included fuse.
Cons: No RCA sound cable for subwoofer
have used several of these for other unit installations, good quality material.
Pros: good quality
Cons: price, I mean its just short lengths of wire for crying out loud.
This kit costs a little extra, but is well worth the cost. There's a reason some kits are $20 and others are $50. You get what you pay for and it doesn't make sense to short change your several hundred or thousand dollar system for the sake of $20-$30.
Pros: High quality components

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.
