Sean from OLATHE, KS on 5/4/2021

Pros: quality compared to other brands online...it is the gauge it proclaims to be...

Crutchfield customer from Sunset, LA on 5/26/2020
This kit is all you'll need for your install. True quality wiring, not like the cheaper China stuff out there. If you plan on running high end audio it all starts with the power supply. Would have given it 5 stars but I wish the power wire was a little longer. I have in a 2018 Sierra crew cab and the amp is under the back seats, it reached just wish I could have had a few more feet.

2017 toyota camry
Stephen from WAHIAWA, HI on 5/23/2020
Overall this amp kit is great, wires feel sturdy and well constructed. This kit provides everything you need to install at least for what I used it for a mono block amp. There is one thing that kinda irritated me and it was the dang fuse holder and fuse lol, maybe it was just me but I constantly had to adjust the fuse holder screws to make sure that the fuse went in well to where its not to tight or to loose and just fly out and short everything. In my opinion I would have rather had a tube type fuse where you just put it in and screw the other end on. The fuse and holder they include to me is garbage but thats just me, don't let my opinion sway your decision, buy the kit yourself and try it out and see what you think, if it wasn't for that fuse and holder I would say its a 5 star kit. Other than that everything else about this kit is great and its a straight forward install everything is already done you just have to run and plug everything in!
Pros: -Great kit -Everything included -Straight forward and to the point -Sturdy wires, doesn't feel cheap
Cons: -In my opinion the fuse holder and fuse combo they went with is garbage

Just What I Needed
Crutchfield customer from Las Vegas, NV on 6/13/2019
A comprehensive package that offers the most common necessities for medium power amplifier installs. While the price could be lower this is still the kit I turn to when installing an amplifier. All the components are high quality and ample wire lengths are included. If I could change anything about it I would up the gauge of the speaker wire and give a few more feet of it as well.
Pros: quality, fairly complete
Cons: price, speaker wire could be bigger and longer

Good stuff
Justin from Kodiak, AK on 11/18/2017
Very nice product. High quality wire set that is very durable and very flexible which helps for installing in tight places! I gave it a 4 star rating due to the only thing i disliked was the way the fuse holder is designed requires the fuse to stick out and be exposed to the elements. i live in a very wet/rainy place where it rains 75% of the year. However , Other than that i love these kits!
Pros: Flexible, high strand count for more current flow. High quality all around.
Cons: Exposed main fuse in fuse holder to water/dirt.

Great wiring kit.
Albert from Conway, AR on 4/9/2017
The Rockford Fosgate RFK4X wiring kit is definitely the kit to get. You can immediately tell that the power and grounding cables are good quality, high strand count which makes it flexible and easy to install. I used it to connect a Rockford Fosgate R1200-1D amplifier driving 2 Rockford Fosgate P2D2-12 subs. I installed this system in my 2008 Jeep Wrangler Sahara. I mounted the amp in the rear of the vehicle, the cable was perfect in length. I used all elements of this kit with the only exception being the speaker wire, since the subs are mounted in the rear I had plenty of wire left. I recommend retightening the power cable on both sides of the fuse holder. I also used dielectric grease on all my connections. Great kit, definitely delivering the power and a good signal to the amp.
Pros: High flexibility, easy to install.
Cons: None.

Watch your length
Brad from Champaign, IL on 3/15/2017
Overall good kit, the only issue I had is the lengths were not long enough for my Trailblazer. If you have a large vehicle with 3 rows of seating, this may not be long enough. I contacted Crutchfield and they took very good care of me.
Pros: Everything you need in 1 kit
Cons: Short lengths on large SUV's

The hookup
Karl from Dundas, MN on 7/5/2016
This is yet another excellent product from Rockford Fosgate. The only issue I have with it is that it is supposed to be for a 4 channel amp but only comes with one RCA cable. Otherwise, everythign you need is here to install a 4 channel amplifier.
Pros: sturdy looks good
Cons: needs second set of RCA cables for 4 channel amplifier set up

Jukebox from Scott La on 6/19/2015
Solid lil wiring kit not too pricy and just what I needed.
Pros: High grade wire and the fuse block was of good construction.
Cons: I would like to see different grounding options included with these kits. Like the terminals that have three holes to get a better ground when you can't get to a bolt location.

Spud from Volcano, HI on 3/23/2015
not bad. everything u need. good quality wire as well. little pricey, but works well. dont get voltage drop or amperage loss at end of 17' run.
Pros: good main wire, good speaker wire, good rca cables
Cons: maxi fuse.... not water tight casing...... make sure its in a good dry spot...... connectors not soldered only crimped. for the price, they could have upped the 'perfectionism' of it. fosgate claims top of the line.... so prove it

Just what I expected.
Dan C. from Cbus, Ohio on 5/13/2014
good set of high quality well insulated cables that when bought with my amp were 50% off just what I expected plus gets you a second year of warranty when used with your Fosgate amp so doubly sweet.
Pros: extra year of warranty and just what you need to install no extra bits needed
Cons: none that I can find other than extremely small terminal connecters on ground cable made it really had to find an actually bolt to fit it in my truck the connector was about a 10mm hole and the safety harness and bolt to my seats (only bolts near unit) are at least 14 mm so would like to see the preinstalled terminal connectors in a bigger size

RFK4X Amp Wiring Kit
Britt C from Richmond, VA on 9/22/2013
I have always trusted the Rockford Fosgate brand. You usually get higher quality products at a reasonable price. But I was disappointed when I opened the kit. The fuse holder was awkward to use, the RCA cables were low quality and the crimp connectors were junk! The only positive was the power cable and ground cable, they were top notch. All parts required for installation were there and my install went just fine but for the money I expected more.
Pros: Power and ground cables were high quality.
Cons: Crimp connectors, RCA cables and fuse holder were of lesser quality.

Great kit, not so great price.
Garrett from OKC, OK on 3/18/2009
Pros: True AWG wire. High strand count <---That's a good thing. EXTREMELY flexible. You can pretty much tie this in a knot without worry of breaks, which makes it your best friend for complicated and cramped installs. The kit is complete with everything you need. More than you need actually! Cons: It's possible you will have to drill out or notch the power ring connector, but this is not difficult with a sharp drill bit or other "correct" tools. The connector is high quality however, so I guess that's a plus. Price. Even for such a great product, that's a steep one. REMEMBER: Be safe, don't mess with live wires!
