Review: Second order! - Love this kit! It's the second time and its awesome.. got it for my s10 the first time and just got it for my civic this time... real coper in a full kit.. has all the zip ties and connectors you would need and at a good price! Review: One of the Best Kits On desertcart for the Price - 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. ## 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 | #276 in Car Amplifier Power & Ground Cable | | Brand | Rockville | | Brand Name | Rockville | | Customer Reviews | 4.6 out of 5 stars 972 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 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 | 1.0 Count | | Warranty Description | 1 Year Manufacturer | ## Product Details - **Brand:** Rockville - **Item dimensions L x W x H:** 7.5 x 7.5 x 3 inches - **Manufacturer:** Audiosavings - **Mounting Type:** Freestanding - **Voltage:** 600 Volts ## Images ![Rockville RWK4CU 4 AWG 100% Copper Car Amp Wiring Kit with Crystal SQ RCA Cables, Silver-Tinned, Gold-Plated Mini ANL Fuse Holder, Complete 2000W Installation Set for Car Audio Systems - Image 1](https://m.media-amazon.com/images/I/61-cZXydGRL.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.

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. ## 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/31172774-rockville-rwk4cu-4-awg-100-copper-car-amp-wiring-kit](https://www.desertcart.us/products/31172774-rockville-rwk4cu-4-awg-100-copper-car-amp-wiring-kit) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-09*
