Rockville RWK4CU 4 AWG 100% Copper Amp Installation Wire Kit, High Conductivity, Durable PVC Jacket, Complete Accessories, for Car Audio Enthusiasts

seller sent fedex so assured of arrival. arrived on third day. seems like very good bang for buck. comes with nice array of spades, grommet, fuse box etc. power cable was over 17 feet. Power cable has ring pre attached loomed and shrink wrapped, other side wire end. (I FORGOT you would need to cut it to splice in the fuse...went to hardware store used their cutter lol ...hey I buy enough there). the cable weighed 1370 g 1.36 kg or 3lb. the ground was 3 foot 1 1/2 inch with ring. ground weighed .24 kg 8.3 oz or 235 g. I tried testing resistance with a garbage multi-meter 3 buck hf lol it said each was basically no ohms in the 200 setting16 ft power, 3ft ground and a 1 foot piece?! meh wish i had a fluke or real equipment lol.jacket diameter 10 mm .39. conductor approx 6mm or 1/4 inch hard to say due to its shape. seems fairly bendable probably about 4 inches to do a 180.The kit i received rwk4cu all the power cable that i cut and the ground ...all three ends held together looked similar tinned copper stuff depending on angle i held it could make one look one way or other... i got the kit june 2021. i was worried about the pic from earlier review.the whole set seems great for the price. was trying to figure out how much copper is in it so hence all the measurements. its a loose weave so it can bend flex like seems like these modern audio cables do. really hard to trust anything anymore so i figured i would post what i can to help fellow shoppers. and since i am pleased with kit so far support the seller. NOTE the ground doesn't have the ring on it pre attached either (i figure they give you options so you can customize for your specific system build), so i used the rubber sleeve and included ring and yep used a Klein lineman pliers to crimp it at the hardware store...sorry not buying 60 -100 bucks in tools or what for 1 cut and a crimp i do once in my life lol. at least the kid in the dept was impressed by the size of my cable. you can do the ball bearing vise thing if you have that .I would prefer the other type of fuse holder that's water proof but this one is more showy for those that are into that. Since i don't off road or use this in marine setting id prefer a solid copper old school but now days probably cost at least 3 bucks a foot. maybe this tinned stuff is ok. I am not touching aluminum clad cca. Went up to 4 gauge and probably 6 would have been fine so I've compensated for the weave and tinning, as well as left room to add on.have an old 24 ft monster bass 400 subwoofer rca line that i got good deal on years ago. it really is beefy compared to the included one. (the internal strain relief is like 3 times the size and the shell metal way thicker lol has actual silver solder and gold plate etc). the kit rca seems neato not sure which has better shielding properties. or if it makes enough difference. ill probably use the kit rca. as i have been using just the the left sub channel from head don't know if that matters either, but the kit has one for right and left. anyone has ideas let me know!

update: January 2020After using this kit for awhile it is holding up really well, I get nice stable current to my amps and DSP, I keep seeing saying this is not OFC with a picture of silver strands on the black cable, IT IS TINNED COPPER, that is done to prevent corrosion since allot of the time people will run the ground to the car frame under the car, look up what tinned copper is and why it's used. The only error in the description is the strand count, they say 1862 but it's actually 1911 (7×7×39) which is a good thing. Don't forget to get some furrels and good 4awg crimp lugs along with good dual wall heat shrink for a great install and perfect connection.Very nice kit, the box could have been more study though, first one arrived with missing parts due to box blow out. Cable is true 4awg OFC, very flexible with a thick jacket, major props from the mesh sleeving on the power cable, adds extra protection under the hood. Fuse block is very well made. Speaker wire is flat so running under the carpet looks nice since you won't have jumps. Ground wire is tinned OFC, big props for that since that will help keep corrosion at Bay. Nice assortment of grommets, crimp connectors and boots, even threw in some zip ties. All in all it is a very nice kit for a fair price. Running two amps off it, 1500w rms system, wires do not get warm or have any strange power droops.

Fantastic kit for my rockford mono-block. For $50 you get everything in true OFC copper, this kit has a lot for the money. The RCAs are really nice quality, all the wires are nice and flexible, and the hardware that comes with it is also good quality. I really liked how the power wire already came with tech flex, heat shrink, and the terminal already installed for the engine bay, that saved me some time and looked great out of the box.The only downsides are the fuse size and the fork terminal connectors. The fuse is 120 amp, I dont know about you but if im running a system pulling 120 amps im running 1/0 gauge, that seems like overkill for a 2000 watt max wire kit (Personally wounldn't trust 4 gauge at 1500 watts RMS to be honest) . Most people dont even have a 120 amp alternator if they are driving a regular sedan. So i paired it with a 50 amp fuse for $5 (recommended size for my rockford amp) problem solved no big deal. The fork terminals are useless for the rockford amp since they are set screw terminals. If it came with wire ferrules as well as the fork connectors it would be 10x more convenient for all those guys out there who want an extra clean build.

Really solid kit for the price.I wouldn't hesitate to buy it again or suggest it to anyone. The power cable comes with abrasion jacketing and ring terminal already installed. Fine conductor strands with very pliable insulation on all wires so getting them to follow contours is easy. Just a one sticking points that made it a 4 star kit. The ground cable I received is not OFC. I got a second opinion from a professional installer who agreed with me. The jacket had OFC printed on it, the wires were silver and it was lighter then the same length of known OFC 4 gauge. My grounding point was inches away so I went with it or I could have used a length of the other cable. .Still would have been nice to know when I purchased this 100% OFC kit that it wasn't.
