1 Pair — 1/0 Gauge to 4 Gauge Car Audio Power/Ground Reducers What this does Converts oversized 1/0 (and 2/0 welding) power or ground cable to a 4 gauge amp input so you can connect capacity vehicle wiring to amps or distribution blocks with 4 AWG terminals. Offset design eliminates clearance and fitment problems, providing a neat, reliable connection where bulky cables would otherwise interfere. Key benefits Reliable connectivity: Adapts large battery or weldingstyle cable to common 4 AWG amp inputs without cutting or splicing the main run. conductivity and corrosion resistance: Machined from 6061 aluminum and nickelplated to maintain strong current transfer and longterm performance. Secure, simple installation: Includes two wire reducers and stainless steel set screws for firm fastening; installs quickly using common hand tools. Versatile compatibility: Accepts standard 1/0 car audio wire, 1/0 and 2/0 welding cable, and fits most car amplifiers and distribution blocks with 4 gauge inputs. Features & specifications Quantity: 1 pair (two reducers) — one for power, one for ground. Input side: accepts 1/0 and 2/0 welding cable or standard 1/0 car audio cable. Output side: 4 gauge amp input. Material: 6061 aluminum alloy with nickel plating. Hardware: stainless steel set screws included. Design: offset body to prevent interference and simplify routing. Practical applications Upgrading an amplifier: Connect your vehicle's 1/0 battery cable to an aftermarket amp that accepts only 4 AWG inputs without rerunning power cable. Using welding or heavygauge cable: Convert weldingstyle power runs to fit 4 gauge amp terminals when installing power systems or custom electrical layouts. Simplifying ground distribution: Adapt large chassis or battery ground cables to standard 4 AWG grounding points for cleaner, more secure grounding on multiamp systems. Why customers choose these reducers Avoids cutting or splicing expensive battery cable runs while providing a compact, secure adapter for 4 AWG amp terminals. Built for current audio systems where both conductivity and corrosion resistance matter. Includes the fastening hardware you need to get a solid connection quickly. What's in the box 2 x 1/0to4 AWG wire reducers Stainless steel set screws for secure fastening Installation note Fasten with common hand tools. Ensure cables are properly stripped and secured under the set screws for reliable current transfer and safe operation.
