Rockford RFK4X 4 AWG Complete Amplifier Install Kit

Expensive but quality components to connect my new sub to Pioneer 2000A 5channel amp!

I had plenty of length for my 16 F150. The 8ga wire was also perfectly matched for my Rockford Fosgate Prime R2-500X1 (500 watt) amp. The RCA wires, years ago, used to come molded with the amp power turn on wire molded into the middle of them. Theyve since removed that, so you have to run the Blue wire separately or parallel to them now. Not a big deal, but it was kinda handy the old way.

Ive been using RF wiring for years and the quality remains top notch.

This is the wiring kit that was used in my car for my Sub woofer installation. The installation consisted of a Kenwood receiver-wired to an Kenwood 1000w Amp-then connected to a Kenwood 1200w sub. This cable was plenty long enough to reach from the front to back of the vehicle (Chevy Malibu), and with a bit of wire to spare (even running the power and RC cables on different sides to avoid them from creating distortions). The wire is very thick, and after cutting off about an inch of it for a clean workable cable, it is clear that it is very dense and pure copper. The cable is also surprisingly flexible for how thick it is, and is easy to work with. I would definitely recommend this kit. It even comes with extra wire adapters I used to hook up some LEDS in the car. Thanks Rockford for being great per usual.!

Im an electrical engineer that on some days works with more wire and cable than most people do in their lives. I was an engineer at a wire and cable production facility for several years. We produced wire and cable for the DOD, aerospace industry, military and were contract a production facility to several enterprise grade network cable brands. My brother in law purchased this set when he asked me to help him install a stereo in his car. The good: Highly stranded for high surface area and signal transmission. Soft supple jacket makes it easy to work with. Gauage seems fairly accurate. Comes with 100amp maxifuse and lots of connectivity. The bad: I knew picking up a cable, by the weight, it wasnt pure copper. After doing a scratch and cut test on some strands, theres aluminum in it. Cutting several strands reveals a silver colored core or aluminum. Rubbing it with your fingers and the copper rubs off and reveals aluminum. Scratching the side of a few strands with a knife reveals aluminum. The ground wire was extemely low content copper, and where I would assume they are offseting losses from higher copper content power cable. In all fairness the packaging doesnt state its 100% copper. They just tout a higher copper content than their competitors, due to more strands and a thinner jacket, which makes it close to 4awg. Its a little misleading. The speaker cable is low guage with a thick jacket. Skeptical of it being a 16awg conductor. In all, at this price point, I was doubtful of it being 100% copper 4awg high strand cable. They make no claims on the packaging of it being 100% copper core. Its not as bad as some of the abominations Ive seen from China. However, those saying this is pure copper are incorrect. This is definitely CCA with a higher copper content than some, but still not pure. *As a sidenote, I tried taking pics with my phone of the aluminum showing, similar as to another review I did where someone was passing low guage CCA off as high guage pure, but they didnt turn out well due to size of the strands and a poor cell camera. The stereo has since been installed so Im not able to try again.

The wiring that comes with this kit is very good. Rockford Fosgate doesnt try to cut you short anywhere on the wiring. They give you plenty of wiring and the installation was very easy for me.

Very Disappointed!!! Reserved product open and box was barely taped at all this was obvious return item! This was suppost to be a brand new product but obviously not! Would NEVER buy again from them!! BEWARE

Love how it’s just a plug and play kit with no crimping needed. Everything’s all good to go

Best power wire you can get it feels like angel hair ugh I love it and the shield is very thin so you know it isnt half plastic

Hey guys! Im a Car Audio freak, and id like to make sure people know, that for one Rockford Fosgate is a 100% trusted brand, everything they say is true. Another thing is, just because this comes with a 100AMP fuse does not mean you need to use it. Alot of people think they do because amp kits, nowadays, come with the inline fuse. This is a BIG rookie mistake. [...] The link i just posted tells you all about what AMP fuse you really need. For example the Rockford Fosgate Prime R500-1 500-Watt Mono Amplifier (http://www.amazon.com/Rockford-Fosgate-R500-1-500-Watt-Amplifier/dp/B001P86SMK/ref=cm_rdp_product) has two 30AMP fuses. This makes a basic 60AMP current. Now if you put the 100AMP inline fuse in the inline holder, your amp will blow because its been overloaded by 40AMPs. Think of your inline fuse holder as a gatekeeper, and your amp as a village. Your gatekeeper can let 100 people in (100amp fuse) however the village can only vacate 60 (two 30 amp fuses) people. If the gate keeper lets in 100 people the village becomes overloaded, hence the term amp overload. Its best to keep the 100AMP fuse in a draw for safe keeping and purchase a 60AMP inline fuse (AGU) with gold plated ends for best connectivity. Just make sure you match your amplifiers AMP fuse(s) to your inline fuse. (i.e a 60 AMP fuse to a 60 inline AGU). If you do not take heed to my knowledge, far worse things than your headlights dimming can happen. Freak fires burning your sweet ride to the ground, meltdown of the terminals, amp catching on fire, your inline amp fuse blowing. List goes on, but please take notice of my knowledge ill save you alot of money and chin scratching.
