Rockville RWK0CU 0 AWG 100% Copper Amp Installation Kit - High Power

In this review the Rockville RWK0CU 0 AWG kit is judged as a serious choice for car audio enthusiasts who need a true 0-gauge, 100% copper solution. The bottom line is simple: installers chasing maximum conductivity and accurate gauge specs will appreciate the cable's silver-tinned, oxygen-free copper construction and high strand count, which the reviewer found delivered lower resistance and easy routing in tight engine bays. For anyone wiring a powerful amp or dual amp setup up to the kit's intended 3000 watts RMS class, this kit offers a complete, confidence-inspiring package.

Key Features

• 100% Copper Construction: Silver-tinned, oxygen-free copper provides superior conductivity compared with CCA and reduces voltage drop under heavy loads.
• Complete Installation Solution: The kit includes power, ground, RCA, speaker cable and a 250A ANL fuse holder so most single or dual amplifier installs can be completed without extra purchases.
• High Strand Count: A 4704-strand power cable lowers resistance and keeps amplifiers cooler during sustained high-power use, which is important for bass-heavy systems.
• Durable Flex Design: SuperFlex insulation and a nylon-braided outer jacket make the power cable resistant to heat, vibration and abrasion while remaining easy to route.
• Triple-Shielded RCAs: Twisted pair, 100% copper, triple-shielded RCA cables help reduce interference and preserve a clean signal path for high-end sources.

Who It's For

This kit is aimed at car audio enthusiasts and installers planning medium to high power systems who want a true-spec 0 AWG copper kit that matches advertised gauge and copper content. It suits people wiring single high-power amplifiers or compact dual-amp setups who value low resistance and durable routing materials.

Those who should look elsewhere include casual users installing low-power systems where a full 0-gauge kit is overkill, and buyers who need specialized lengths or connectors not included here; the kit is generous but fixed in the included lengths and components.

Pros & Cons

Pros

• True 100% oxygen-free copper cable yields better current flow than CCA alternatives.
• Comprehensive accessory selection lets you complete most installs without extra parts.
• Flexible, nylon-braided power cable is easy to route and resists heat and abrasion.
• High-quality, triple-shielded RCA cables reduce noise for clearer signal transfer.

Cons

• Some customers reported concerns about the included fuse quality, so installers may prefer to upgrade the fuse assembly for long-term reliability.

Frequently Asked Questions

Is this kit truly 100% copper?
Yes, the kit uses silver-tinned, oxygen-free copper and is sold as a true 100% copper 0 AWG cable.

Will this kit support dual amplifier installs?
The included lengths and accessories are intended to handle single or compact dual amplifier setups; very large multi-amp systems may need additional cable or longer runs.

Are the RCA cables shielded well enough for high-end systems?
The RCA cables are triple-shielded and twisted pair, which reduces noise and is suitable for high-performance car audio installs.
