This wiring kit does not include speaker wire, so you'll need to purchase that separately to complete your amp installation. This kit includes patch cables for a 2-channel or mono amp — you'll need to add cables for multi-channel amps.
Your amp needs big power wires in order to deliver top performance to your sound system. Rockford Fosgate's RFK8i amplifier power and signal wiring kit supplies everything you'll need to send power and input signals 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.

Good enough for me
everything you need in one package!
Pros: Everything you need plus extended warranty for free on select amps!
Its wiring pretty simple to be happy, the zip ties could be a little bigger though.
Great to have the online fuse already mounted and set. Using this kit to do my first install was pretty straightforward. Only thing that sucked is the ground cable is way too short.
Cons: Ground cable it too short.
Pretty straight forward, all connections are snug and great quality
Pros: Materials are great, snug fitting. Plenty of length
Awesome kit! Came with everything I needed (aside from the speaker wire).
Pros: Comes with everything you need, aside from the speaker wire.
It was pretty easy to use. Only downside was it didn't come all connections as pictured.
just about everything you need besides speaker wire.
everthing you need.
Pros: Just what you need. Plenty of length and easy to work with
I'm glad I spent the extra cash and got the complete power and signal kit from Rockford. I use this in conjunction with my Rockford P300-12 powered subwoofer and everything in the kit is high quality. It was especially nice to not have to splice in the fuse as it was already attached to the power cable. The casing on the power and ground cables is durable, and all the cables are plenty long. I ended up swapping the ring terminal on my ground wire for a larger diameter one to allow it to fit around my chassis bolt, but that came included with my sub so it was easy to do. I would definitely recommend spending the money to get this name brand kit as it has everything you need for a powered sub and is all very high quality. I would have gotten a larger gauge if I had installed more than 300 watts.
Very well made product. Rockford has been around awhile and the quality still seems to be a priority of theirs. Everything was as advertised.
Pros: Has everything you need(except speaker wire). That was clear when ordering. Good quality product
Cons: None that I have found so far.
came up 2 ft short. had to re-route the passenger side to connect to amp
Nice solid amp kit. I had to buy a package of split loom for added protection. Overall I am happy with purchase.
Pros: 25% off when I bought with Rockford powered sub. Added additional year warranty to my sub.
Cons: For price it should include some split loom.
Good quality kit for an amp install. Nice quality wire that is very flexible and easy to run.
Pros: Good looking kit and flexible wire.
Cons: I wish it had included a couple of feet of split loom to make the battery connection look more factory.
This install kit was perfect for wiring up my new powered sub. The was enough wire to run from the battery to the trunk and I didn't need any additional parts.
Pros: Had everything I needed.
Cons: None so far.
This is a very nice amp install kit. It feels and looks high quality and the lines are dense and incredibly flexible which makes it super easy to route them and fish them through your vehicle and conceal them. I actually ran them through the hollow center of my door seals for a distance and all i had to do was push them in through an opening.
Pros: Flexible, easy to route and work with
I chose this wiring kit as it was recommended when I purchased a Rockford Fosgate 12" powered subwoofer. The installation was pretty easy. I liked the fact that the fuse holder is already wired. The only gripe I have is that the power cord from the battery to the fuse holder is so short that I can't mount the fuse holder to my car. It just sits near my battery and air filter housing.
Pros: Easy installation
Cons: I wish the power cord from the battery to the fuse were a few inches longer, so I could mount the fuse holder to the body of the car.
Bought this along with an RF amplified sub and I'm glad i did. I obtained a price discount from Crutchfield and an additional year extended warranty from RF. Wiring is good quality and it had all I needed to complete my installation.
Pros: Good quality wiring
Bought this with a p300-10 amp/sub. Mainly because I wanted good quality wires but secondly because I got extra off buying it together with the sub/amp. I used the kit to run 8awg from my trucks battery (1994 Chevy K1500 extended cab) to under drivers seat, where it went to a capacitor and then on to the P300-10. Wires all appear to be all copper, which is what I wanted. Hardest part of the install was running the wires under the carpet, but that is why I bought quality so I would never have to do it again!
Pros: Good price Good quality
Cons: Not a fan of fuses, would be nicer if they provided a breaker instead
simple and easy, only one suggestion get your own zip ties the ones in the kit are crap.
Pros: great quality wire and connectors
Cons: zip ties suck
Had everything needed to install the amp
Pros: Great quality at a good price
Works perfectly. All cables are long enough to install properly on a 2008 Ram Quad Cab.
Included everything I needed to install my amp
Pros: Great kit
Quality in this kit is very good. Cable lengths just right for my Outback. Only complaint is it comes recommended for the sub I purchased, but came with a 60 amp fuse. The sub I purchased, the Rockford Fosgate Punch P300-10, needs to be fused a 30. Crutchfield does not carry 30 amp AGU type fuses. Neither did anyone in my area, not even the pro installers. I had to order one from the internet. Delayed installation by a week. If you order this kit know it come s fused at 60 amps.
Pros: good quality cables good length provided
Cons: Fused at 60 amps no other options.
Rockford fosgate amp wiring kit got the job done! Good quality cables and connectors. Crutchfield once again with awesome shipping.
Pros: Quality cables Good length
Purchased this wiring kit to augment a Rockford Fosgate Punch P300-10 installation. This wiring kit provided all necessary wiring to connect power, remote-on from the head unit and RCA line out to the Rockford Fosgate Punch P300-10 subwoofer. The length of wire(s) was more than enough to provide connectivity from the battery to the subwoofer in the rear of the vehicle. I would recommend this wiring kit, as it is an excellent choice and provides exceptional connectivity and power delivery.
Pros: 1. Included everything I needed to install a powered Rockford Fosgate Punch P300-10. 2. Delivers exceptional power and sound quality.
Cons: 1. Would like to see an extra Fosgate barrel fuse; though a barrel fuse comes with the wiring kit, if it blows, I will need to order another-which will take time to receive.
Very simple install!! No problem with the lengths of any of the cables; 1998 Z71 extended cab...
I love anything thats Rockford Fosgate ... Its a good wiring kit. I liked the flexability of the power wire which made it easy to work with, not stiff and hard to work with wire that i had before. Patch cables are very nice and fit snug. Nice ground wire too, just wish it would have been longer. And i didnt care much for the remote blue wire to amp, it could have been a slightly bigger gauge so i used my own blue remote wire that i bought at a hardware store.
Pros: nice power wire and fuse. nice patch cables
Cons: short ground wire (at least in my opinion) and didnt like the small gauge remote turn on blue wire, so i bought a heavier gauge at local hardware store
This wiring kit worked awesome for me in my 2009 Subaru Impreza WRX. The clarity is awesome with little to no distortion. Rockford Fosgate is an awesome company with amazing products!
The heavy power wire has a heavy duty in line robust fuse and holder. The entire package has everything you need to get power to the amp.
Pros: Has everything you need to get power to your amplifier. High quaility and heavy duty wiring.
Cons: It is 2015... Can we just come upbwith packaging that doesnt require a jack hammer to get into?
A great quality kit. Rewired my Nissan Titan with new speakers, crossovers and power amp and this kit made installing the power amp a breeze. Comes with everything you need to hook up the power amp and all the cables are of great quality. Would highly recommend this product to any body doing the same install.
Pros: Made of high quality materials. Cables are long enough to get the job done.
Kit comes with everything you need, except speaker wire. Very good quality product, and enough cable length.
Couldn't be happier. Made installation a breeze. Installed in a '99 Ford Ranger extra cab two door. Had more than enough wire. Couldn't mount the fuse holder, but that not the products fault, just didn't have a location under the hood.
Pros: Makes installing an amp extra easy. I would have hated to buy everything individually.
Cons: Wish the RCA cable ends would have been better color coded, they are light grey and dark gray.
Great product but could use an extra split cable for the 4 channels
I purchased this to wire up a new powered subwoofer in my 1994 Bronco. I'm glad I did, this is an excellent kit with everything that I needed. Great quality.
Nice kit but the power cable came up a bit short in my 2-door hatchback (specific routing in the engine bay, I wasn't wasteful) You would think 17 feet would be enough but alas, it wasn't. Crutchfield came to the rescue though and sent me nearly 6 more feet when I only asked for 2-3.
This product was very easy to install everything it said was there, were there the only problem is nothing was gold plated. I did a search in google to find gold plated rca cables. it brought this product up and it was hard to see if they were gold plated, turns out they are not, otherwise it is a great product.
Pros: quality product, easy to install, looks good
Cons: not gold plated, RCA cables seem a bit cheap
This kit for installation for amplifier is very good.
Pros: Makes wiring easy. No piecing together a wiring setup for your audio setup.
Cons: The signal cable is way small. It's nice a long, but I could have just used cheap speaker cable for the signal cable.
Great for my 600 watt amp install
Cons: No speaker wire
Nice kit, worked great on installation
Pros: Works great
you will need this if you want to add some Thump to your system all in one kit Very Nice.. Im glad i got this...
Pros: has everything you need
This was exactly as advertised! The rep I spoke to recommended it, and it came through in flying colors. Easy to install.
Pros: Easy install, great instructions
This is a great amp wiring kit. It was just what I needed.
Pros: Great kit!
Cons: The fuse holder was broken.
An amazing product plenty of wire to reach everywhere.
more than enough mateerials, high quality!
Pros: Everything you need for cheap and high quality
There really isn't anything overly bad that I can say about this installation kit. The wires and cables seem to be high quality and work fantastic. I do have to agree with other reviewers in the fact that the power wire could be longer (probably by a minimum of three more feet). I would like to give the product four stars instead of five because of this but it wouldn't be fair; I purchased it knowing that the wire is only 17 feet long and that it would be a slightly tight fit. It did, fit, however (it's in a 2000 Honda Accord 4dr, if you're wondering). I can definitely recommend this product.
Pros: The quality of the components.
Cons: The mounting bracket for the fuse seems flimsy, and the first one I received was done so in a broken form. Crutchfield did replace this with no questions asked, however.
Great kit, came with everything i needed for my bass package install and head unit. Power wire is easy to hide and snake through tight places.
Wiring package worked out great. If wires are too long, do not leave coiled up; they may cause resistance or buzzing sounds to your unit.
Has all you need to hook up amp, thanks Rockford and Crutchfield!
Good quality cable and fuse holder. I ran out of length on the power cable. Be sure to measure. Large SUV's probably need a 20-25 ft power cable.
I was very glad to have this kit. The power wire could be just a tad longer though.
Since being in school for electrical engineering I'm always looking for the best quality I can find for my systems. Rockford Fosgate shines through again with this great wiring kit! Very high quality power cable that is durable yet flexible making it easy to hide away in the increasingly more difficult to wire up cars of today. Great RCA cables with a solid connection, no interference whatsoever. Kit came with everything I needed and I can say it all came out great, plenty of power for my 600Watt amp pushing 1 sub at 2 ohms stable.
this wire is premium quality and easy to work with.
Great product and perfect for a mid range power amp.
Outstanding in every way. Well engineered and designed. I did not receive the assortment of connectors that is pictured, though I had what I needed for the job. The insulation on the RCA cord and power cord are soft and supple making routing a breeze. It is a bit expensive, especially compared to alternative products. But if you're the type that doesn't mind paying for the best, you won't be disappointed.
Guys, if you are looking for an 8 gauge wiring kit, this one will provide for all your power needs. It comes with everything you need. The power and ground cables are excellent. The overall quality is excellent. Both ground and power cables are very flexible and is very easy to handle during installation. I highly recommend you buy this if you are looking for an 8 gauge kit. I rate this +5
this is a great kit! i'm very happy i went with it over some of the cheaper ones out there.
The kit has everything you need for an easy amp installation
You bought an amp, you NEED THIS! Period. It includes everything to wire your new amp properly. Without this kit it would have taken me twice as long, easy, to have gotten all my cables sorted and connections just right. Everything I needed was here. Everything. Did I say that enough? Everything. (Besides tools)
Best wires your going to get. Buy the kit and do it right.
Glad I spend a few extra bucks for this kit. Biggest driver for me was getting something economical that had a common type of fuse. No issues with install. Came with more than enough connectors and accessories.
very good quality, but should include spade connectors for the power and ground wires, it only includes one for the remote wire
The wire in this kit is very flexible and easy to push through grommets and pull through small spaces. The strand density is top notch too. Wire length is more than enough for full size suv's unless you're wasteful. No speaker wire is included and the miscellaneous connectors are much fewer than indicated in the pictures but I didn't need any. The fuse is a more readily available design compared to other kits and that was the main reason I purchased it.
This has some good heavy wire and just about everything you need. In the "What's In The Box?" caption it lists a bunch of misc. connectors that you can use for speakers and some other wiring. Well I had hoped this product had those speaker connections but it only came with one. Now I have to go to the store and get several. Also, ended up pulling apart the 60A fuse because it's such a tight fit. Just a couple of set backs.
This amplifier wiring kit is well worth the money! This kit was unbelievably better than the wiring kit I owned before. If you can afford spending a little bit more for this rockford fosgate kit, do it. You will not be disappointed.
Kit comes with everything you need. Nice quality cable. The fuse is a normal inline fuse so if it blows you just replace it with a fuse at a local retail store, no need to order a special fuse. Would be nice if they would of included a spare fuse, but no biggie. Also no speaker wire included. <BR><BR> I have this hook up to an Alpine M450 pushing 400watts to a JL 10w3v3 at 2ohm and works fine.
General Overview: This is a single amplifier wiring kit that includes the power and ground cables, turn-on lead, one pair of stereo RCA cable and accessories required to install one amplifier. Speaker wire is sold separately.
High Strand Power/Ground Cable: The power and ground cable are 100% Pure Crystal-Oxygen Free Copper (PC-OFC) and meet or exceed AWG (American Wire Gauge) requirements.
In-line Fuse Holder: The included in-line fuse holder attached to the power cable comes with a 60-amp AGU-type fuse.
Patch Cord: Twisted pair cable design is used for noise rejection, a split center pin helps secure the connections at both ends.

Hey JC; I'm going to say "probably not" to that if you're running completely hidden. I used this kit for trunk mounting in a '99 Beetle routing it properly hidden under and behind panels. I had a bit over 12" to spare. Routing it hidden eats up cable very quickly. Hope this helps. John W.[ John Aug 08, 2017 ]
