Review: Great value nice assortment cant find any better anywhere near price point reasonable name - 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! Review: Great value for a true spec OFC kit - update: January 2020 After 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 (7Γ—7Γ—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. ## Features - HIGH-PERFORMANCE COPPER WIRING: 100% oxygen-free silver-tinned copper (OFC) with 1862 strands ensures maximum conductivity and minimal power loss, delivering clean power to amplifiers up to 2000W for superior car audio performance. - COMPLETE INSTALLATION KIT: Includes 17 ft power wire, 3 ft ground wire, 17 ft remote wire, 120A Mini ANL fuse, gold-plated fuse holder, ring and spade terminals, and zip ties for a hassle-free setup. - PREMIUM AUDIO CABLES: Crystal SQ 14 AWG flat planner speaker cable and triple-shielded Crystal SQ RCA cables provide high-fidelity signal transfer with reduced noise and optimal clarity. - DURABLE AND FLEXIBLE DESIGN: Rugged SuperFlex PVC jacket allows easy routing in tight spaces and withstands harsh automotive conditions, BC-5W2 compliant for marine-grade quality. - SUPERIOR TO CCA ALTERNATIVES: Pure copper construction with silver-tinning delivers better current flow, corrosion resistance, and long-term reliability compared to copper-clad aluminum kits. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B019Z3RCG2 | | Best Sellers Rank | #80 in Car Amplifier Power & Ground Cable | | Brand | Rockville | | Brand Name | Rockville | | Connector Type | Ring and Spade | | Customer Reviews | 4.6 out of 5 stars 975 Reviews | | Global Trade Identification Number | 00811080023014 | | Included Components | Power Wire^Ground Wire^Speaker Cable^Rca Cable^Remote Turn on Wire^Fuse and Fuse Holder^Wire Loom^Installation Hardware | | Item Dimensions | 7.5 x 7.5 x 3 inches | | Item Highlight | 1000W-2000W RMS Systems, Silver-Tinned Copper, 1862 Strands, 120A Mini ANL Fuse, BC-5W2 Compliant, 17ft RCA Cable | | Item Weight | 5 pounds | | Item dimensions L x W x H | 7.5 x 7.5 x 3 inches | | Manufacturer | Audiosavings | | Material | Copper | | Material Type | Copper | | Model | RWK4CU | | Number of Items | 608 | | Part Number | RWK4CU | | UPC | 811080023014 613815618218 | | Unit Count | 1 Count | | Warranty Description | 1 Year Manufacturer | ## Product Details - **Brand:** Rockville - **Connector Type:** Ring and Spade - **Item Weight:** 5 pounds - **Item dimensions L x W x H:** 7.5 x 7.5 x 3 inches - **Material:** Copper ## Images ![Rockville RWK4CU 4 Gauge 100% Copper Car Amp Wiring Installation Kit, OFC - Image 1](https://m.media-amazon.com/images/I/61-cZXydGRL.jpg) ![Rockville RWK4CU 4 Gauge 100% Copper Car Amp Wiring Installation Kit, OFC - Image 2](https://m.media-amazon.com/images/I/51CPgFeeJHL.jpg) ![Rockville RWK4CU 4 Gauge 100% Copper Car Amp Wiring Installation Kit, OFC - Image 3](https://m.media-amazon.com/images/I/51j-pp57UkL.jpg) ![Rockville RWK4CU 4 Gauge 100% Copper Car Amp Wiring Installation Kit, OFC - Image 4](https://m.media-amazon.com/images/I/51eQOWUdqhL.jpg) ![Rockville RWK4CU 4 Gauge 100% Copper Car Amp Wiring Installation Kit, OFC - Image 5](https://m.media-amazon.com/images/I/518tm7IPntL.jpg) ## Questions & Answers **Q: I heard that the ground cable was cca is that true?** A: When I purchased the kit in August 2017, both power and ground wires were OFC. **Q: Several people say this is not true OFC that it's actually CCA. Who's telling the truth here???** A: The kit I purchased in July 2017 was definitely OFC copper cable, true 4 ga (NOT 6 ga with extra thick insulation to make it look like 4 ga). Maybe they switched to Copper clad aluminum sometime after that..... **Q: Is this 100% ofc? i dnt want cca.** A: Yes, the ground wire is tinned OFC, the power wire is pure copper, 1911 strands. The speaker wire is also OFC, the RCA patch cables are OFC twisted pair. Grab some furrels and good copper 4awg crimp lugs and dual wall heatshrink for and good install **Q: What does ofc mean?** A: Oxygen Free Copper. Copper and aluminum are the most commonly used wire materials and there is a significant difference in quality, power handling and signal transfer between these materials. The least costly between these 2 options is Copper-Clad Aluminum (CCA) wire. CCA wire utilizes an aluminum core that is clad or dipped in copper. It is a suitable choice for lower powered systems or restricted budget applications, although the power transfer is not on the same level as the far superior Oxygen Free Copper (100% OFC) wiring. OFC wiring is refined to remove virtually all oxygen and other corrosive elements. it’s ideal for wiring, however this product is a little misleading. Not all of it is OFC.

It says it's all copper wire for the 4 gauge power wire but when I spliced it to put the ends on it the wire appears to be silver with a bit of copper color. Now I don't know much about wire specs, and for all I know it could be all copper and I could be wrong. The wire is very manageable and is not hard like other wires. The length of the power wire was perfect to run from the passenger side battery across the engine bay and into the truck thru the driver side to to back of the cab (Silverado extended cab). It also came with a gromet to put on the firewall to seal it, and also came with all the end connectors needed and a 150a fuse to complete the install without having to go and buy anything. All in all I will definitely but this kit again if I need another one. ## Frequently Bought Together - Rockville RWK4CU 4 AWG 100% Copper Amp Installation Wire Kit, High Conductivity, Durable PVC Jacket, Complete Accessories, for Car Audio Enthusiasts - RECOIL RCI417 100% Oxygen Free Copper 17ft 4 Channel RCA Audio Cable Twisted Pair with Noise Reduction, Speaker - Rockville RXH-F5 3200W 5-Channel Car Amplifier, Dyno-Certified RMS, MOSFET Power Supply, ELNA Capacitors, Class-A/B D, Perfect for Car Audio and Subs --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/31172774-rockville-rwk4cu-4-gauge-100-copper-car-amp-wiring-installation](https://www.desertcart.tn/products/31172774-rockville-rwk4cu-4-gauge-100-copper-car-amp-wiring-installation) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-20*
