This kit includes patch cables and speaker wire for installing two 2-channel or mono amps — you'll need to add cables and speaker wire if you're installing a multi-channel amp along with a second amp.
Your amp needs big power wires in order to deliver top performance to your sound system. Rockford Fosgate's RFK4D amplifier wiring kit supplies everything you'll need to send power and signal to two amps and your speakers. It's designed for amplifiers with fuse ratings totaling up to 100 amperes.
The kit includes two distribution blocks, 4-gauge power and ground cables, 8-gauge power and ground cables, speaker wire, two patch cables, a fuse holder, a 100-amp fuse, and more. Rockford Fosgate makes these cables from 100% pure crystal-oxygen free copper wire so you can count on maximum signal transfer.

Very good product
Pros: Very good product
So I initially was skeptical about buying a pre made dual amp wiring kit. Only a few things was missing but I couldn't expect it to be perfect.
Pros: Very pliable, if you bend it and give it a nice little squeeze it will stay bent in that direction but very easy to straighten after wards. It exceeds most gauge regulations for what it is.
Cons: Kit did not come with battery terminals, nor was there a 4 gauge distribution block that kept it at 4 gauge on your split side. Not an issue. Would have been nice to include one of them considering I don't plan on using a distribution block for my grounds.
Quality components come up short in quantity. Not enough wire length for a mid size 4 door. Distribution blocks are nice. Longer wire lengths will be necessary for clean installs.
Pros: Nice stuff...
Cons: ...just not enough of it.
If your are running speaker wire to 4 door speakers in a sedan you will need more speaker wire but everything else you need is there.
Pros: good price for what you get
Cons: I needed to buy more speaker wire. the insulation on the RCA cables is a little thin
Great wiring kit!
Bought this for a complete audio overhaul. Wanted to run 2 amps, one 4 channel for component and one for subs. Installation was a breeze. Includes everything you need, including two distribution blocks. High quality wiring.
Pros: Easily powers two amps, no issue at all. Easy enough to install, and had everything needed to install two amps
Cons: Didn't include enough speaker wire. Not a problem if you aren't running new wiring for every speaker in the car, but with a powered 4 channel amp to my components, the stock wiring would not handle that much power. Had to replace all existing wire, and didn't have enough in this kit. I suggest buying a roll with this kit.
I'm mid-install and I have no reason it won't be smooth but my only gripe is the lack of 8-gauge red cable. There was a lot of 4-gauge but they assume everyone will be running all the way back and splitting there. I'm putting a class-D amp in the dash and then a sub in the rear. My dist block is under the dash. I had to go out and purchase more 8-gauge red cable to do what I needed to do. Also, including some of those self-tapping screws would've been nice.
Pros: RF reputation
Cons: Lack of 8-gauge red cable
Good two amp wiring kit. Easy to use for the most part it comes with everything you need to hook up two amps.
Pros: Dual distribution blocks for power and ground. Good quality wiring also extends the warranty on Fosgate amplifiers!!
Cons: Fuse holder is a little tricky but a great kit. It could of also included a capacitor in the kit because more than one amp almost always needs one.
Made installing my two alpine amps a breeze
Pros: Everything you need for installation of 2 amps.
Cons: Need instructions for the fuse block on how to install the fuse. I figured it out but it would of been nice to just have instructions. Need more RCA lines if using multi channel amps.
It was sufficient for what I needed in regards to 2 amps
Pros: Came with everything I needed to setup two amps.
Cons: The ground wire was not long enough for the second amp had to purchase an additional kit to do the job.
Everything u need. Nothing u don't.
Cons: Price: Buy an amp and get half off and its worth it. Inline fuse holder: not water proof and, not that one would think it would be necessary, no instructions. Fuse doesn't fit in until u remove the Allen head bolts from each side of fuse connector.
Excellent quality, nearly complete kit. Installed with confidence.
Pros: Quality, substantial.
Cons: Wish the kit included patch cable for sub and I wish the main power cable was about 3ft. longer to reach all the way back and across the rear of my F150 SuperCrew.
This kit has everything you will need for a 4 channel amp instill
I use this set up to instal two amps in a mega cab truck. Worked out great. Even had a few feet of extra wire to play with.
Pros: Quality product delivers full power to amps.
This kit comes with all the cables and connectors that you'll need to install your car amps. Cables are high quality and cool looking too. If you have never install stereo equipment in your car you should give it a try because with the owners manual, google and the vehicle specific instructions that the nice people at Crutchfield sends you to you email you should be just fine. Wiring is very important for your amps to get enough juice so this was a necessary investment. Highly recommend this item even if you have one amp for now. Who knows. With this kit additional amps will be a breeze.
Pros: High quality materials, wires, connectors
All the cables had ample length for my install and even the 4 ga. power and ground cables were very flexible and easy to route thru the car. The only drawbacks, IMO, were the power dist. blocks did not provide or offer any covers for any unused output lug's, and the 8 ga. power and ground wires were not supplied with connectors to connect the cables to the amp(s). Other than these two trivial faults, the kit was fantastic.
Pros: All the cables had ample length for my install and even the 4 ga. power and ground cables were very flexible and easy to route thru the car.
Cons: The only drawbacks, IMO, were the power dist. blocks did not provide or offer any covers for any unused output lug's, and the 8 ga. power and ground wires were not supplied with connectors to connect the cables to the amp(s).
The Rockford Fosgate amplifer wiring kit was well worth the cost. It came with everything I needed to install my two amps. My installation went very quick do to having everything I needed in one kit.
Pros: Almost everything I needed was in one kit. Plenty of power wire and speaker wire. The junction blocks having holes so I could quickly secure them to the truck.
Cons: The only negative was I did not have the exact connertors to plug in the power to my sub.
Had everything I needed and more for the 350z set up
Loaded with everything you will need. The 30ft of speaker wire was plenty for my 2010 Civic sedan (a set of components) and the 4 gauge wire was suprisingly pliable for such a thick cord.
Cons: Only a little pricey.
The whole kit is well organized, and I had no issues wiring the power wire under the car. However I drive an 01 s40 so a larger car will have to go through the cabin. And put the fuse in on the main power wire before you fasten it anywhere.
Pros: Almost all the cables have tons on length and thickness. RCAs have plenty of length to
Cons: Could have more speaker wire. Distributor blocks takes the 4 gauge, but only sends out 8.
Great buy, got it half price when I bought my RF T-500-1BDCP so the price was great. It has all the gear to setup 2 amps and also leaves room for later additions. I have been using RF wiring for 12 years with excellent results. The wires is greater in diameter than the other brands instead of having a thicker insulation to fool you. Its very flexible and easy to work with. I am skeptical about the open side fuse holder as others are, but I am going to give it a good ole college try. Would also like 20 feet of 4 gauge instead of 17 feet. All in all great kit, great value, and would recommend it, and buy it again.
Pros: Great value when bought with an amp and get it half off. Great quality heavy duty wire, includes almost everything you may possibly need. Very flexible and easy to work with.
Cons: Wish the 4 gauge was 20 feet instead if 17 feet, unsure how long the open main fuse holder will withstand the under hood elements.
Excellent. the distribution blocks are compact and easy to work with.
Pros: has alot of 4 gauge and 8 gauge wire
Cons: if your running speaker wire to crossovers you would want to but atleast another 8 foot of speaker wire
This kit was easy to use & definitely does the job, but it has about 80% more parts than I needed. If I could have bought just a splitter block and the 4 & 8 gauge wiring I needed, I'm sure I could have saved at least 50%.
This kit has more than enough material for at least 3amps, the descriptions on the package says it does not include a distribution block BUT there are two blocks which have 3 outputs each. As always crutchfield support is awesome!!
Pros: Too many to list.
Cons: No cons
Great product along with fair pricing. Highly recommend this purchase for stereo upgrades. Covered majority of my needs with one purchase. Only improvement for my install, was to double the amount of speaker wire included. Thanks!
Great product for wiring up two amps. The only thing I didn't care for was the fuse holder. It doesn't enclose the entire fuse so it is not water tight. Other than that great product.
This was everything I was looking for and needed. THANKS!
The actual amp cable is of superb quality. Basically all of the hardware has a top notch feel to it... except the signal cables and the speaker wire. The speaker wire isn't even copper, it's of a silver color, and is probably some sort of inferior copper alloy. I did not splice open the signal cable, but through the translucent jacket, they too appear to be made of the same stuff. This is disappointing because these extra pieces are one of the main reasons I went with this kit. (I think this is the only kit with these extras) If you are getting run of the mill replacements for your stock system, I say use these included cables and wire. But if you're going with top notch components, it wouldn't make sense to these throw-in items. I will be ordering high quality speaker wire and signal cables for my system. Despite this, the kit is still worth the money.
pros: awesome kit for the price. i am running two amps (a 4 channel and a mono) and i have no problems with the sound. cons: for my 03 mdx, the rca's ran short. and i didnt care much for the fuse. its rather hard to see once placed inside the holder. overall, i would strongly recommend. great support as usual from the crutchfield team.
If you have 2 amps to install, do yourself a huge favor and get this kit. I thought it was a little pricey at first, but for everything this kit contains and it's quality overall are well worth it. I had a single 4 channel amp, and was adding a mono amp for a subwoofer. This kit includes everything you need for a relatively quick and clean install of 2 amps.
This kit includes everything you need to hook up two amps but it doesn't include another piece of wiring for the capacitor as well as a third set of RCA's if you are running head unit with three sets of pre-outs. Anyway, this unit is awesome because you won't be running back and forth to the store cause it has everything you need for wire runs as well as hooking up both your amps. Awesome!!!!
Great bundle, certainly cheaper than buy items separately. I did need extra speaker wiring which was ok. Cables are great quality and the package is really heavy i.e. lots of copper!
I checked out the other wiring kits for single and dual amps, and this kit by far had the most for your money! I used this to power both my speaker and sub amps. If you are looking to power 2 amps this kit is a no brainer.
This is an excellent kit. Wire and distribution blocks are very high quality. If you're putting in a new amp, main speakers, and a sub as I did, this has everything you'll need to do the install. The speaker wire included in the kit is only single insullated 16 guage though... You might want to buy better, double shielded speaker wire.
Rockford Fosgate is most definately the way to go. This kit has everything you need. Everything i have ever owned that has been Rockford Fosgate I have never had any problems with. The only way to go is Rockford Fosgate.
I purchased this kit after having previous experience with the Streetwires kit. I must say that this is a good kit for the price. It came with two sets of patch cables and 30 feet of 16-gauge speaker wire. However, you would need another set of patch cable if you were running a 4-channel amp or a few 1M/2F adapters. Also, I really didn't care for the Maxi fuse because it was not fully enclosed from the elements. So I switched to the AGU fuse and fuse holder to prevent water damage. Overall, it is a good product.
Excellent kit. Every thing all in one. Worked well in my wrangler; wired up a RF 2-channel and a Kenwood 4-channel.
This kit has everything you will need to wire up two or more amps, depending on their location. I used if to wire 2 1000W amps mounted on the back of the rear seats and had wire left over. The speaker wire was a little less than what I needed, but that was only one piece of the whole kit. My only complaint, and the reason I gave 4 stars instead of 5, there are no screws to mount the distribution blocks with.
This kit had everything needed for my dual amp install. No issues at all. Wire is of stated gauge. Be careful when buying some cheaper off brands as their wire is not always of their stated gauge. I would definitely buy this kit again.
General Overview: This is a dual amplifier wiring kit that includes 4-gauge and 8-gauge power and ground cables, power distribution blocks, turn-on leads, two pairs of stereo RCA cables, a 30' length of 16-AWG speaker wire and other accessories required to install two amplifiers.
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.

Very good all in one amp wiring kit to power up my system. Was looking for good quality for a good price. [ Joseph L. Jan 21, 2017 ]

All in one kit for multiple amps [ Michael Oct 01, 2016 ]
Good brand [ Charles Sep 24, 2016 ]
It has everything that i need to hook up the two amps i just bought from you guys. [ trinidad Sep 11, 2016 ]
Used this before, great product. [ Lyvierre Sep 05, 2016 ]
Friend [ Jonathan Jun 20, 2016 ]
Great product and great quality. Included everything I needed for a 5-channel amp setup. [ jorey Apr 16, 2016 ]
Pure oxygen free copper..I'm adding a third amp as well, so the distribution blocks will work out perfectly. This kit also includes two more feet of 8 awg than the Kicker kit, which I will need. I like the fuse block better on the Kicker kit however. [ travis Mar 15, 2016 ]
Quality wires are needed for quality install in regards to power and signal [ Matt Mar 11, 2016 ]
Installing system and need solid wiring foundation. Looks like complete kit and Rockford Fosgate is high quality. [ Patrick Jan 10, 2016 ]
To hook up two amplifiers [ Sergio Dec 21, 2015 ]
Each amp has it's own fuse, to protect the amps. The fuse on the main power line which is connected to the battery, protects the vehicle. [ Matthew Nov 29, 2016 ]
You can run two fuses! [ Lee Nov 29, 2016 ]
The main fuse is supposed to be near the battery. The power splitter for the two amps may be in the car trunk. If your amps don't have their own fuses and you want them, you may be able to install some. It's a nice kit, and Crutchfield tech support will help you with the install. [ Marlin Nov 29, 2016 ]
Kit will work for that. double check the required cable lengths [ JASON Feb 20, 2014 ]
Absolutely. Crutchfield has thought of everything you may want to use in hooking up whatever system you choose, in any configuration. They have yet to miss anticipating the remotest need I may have in numerous setups over the years, and for a number of different vehicles. [ DOUG Feb 20, 2014 ]
You need additional patch cord to run 4 channel amp [ CHRIS Feb 19, 2014 ]
Yes it does. I used it for a 4 channel amp and a mono amp for a sub. It's a great kit, but I had to buy an extra roll of speaker wire to run since I was running a 4 channel amp. That would be my only complaint, because otherwise it's a great kit. You may not have to depending on your car make and the distance between the speakers and the amps. [ KEVIN Feb 19, 2014 ]
