⚡ At a Glance
  • Connection Quality: Durable brass construction with nickel plating for long-term service
  • Best for: Car and home audio installers adapting or replacing 0–4 gauge terminals
  • Not ideal for: Buyers who cannot confirm exact gauge size before fitting

Brass connectors arrive nickel-plated and use a screw terminal to reduce audio input wiring from one gauge to another. Compact 4.6 x 2 cm units are supplied as a set of four for straightforward replacement.


Reliable Electrical Contact – with brass and nickel-plated construction

Brass provides good electrical conductivity while the nickel plating resists surface corrosion and wear. The metal combination supports repeated insertions and removals without rapid degradation.

Stable contact reduces intermittent connections and helps maintain clear power and signal paths during normal use.

Quick On-site Replacement – thanks to screw-fit terminals

Screw terminals clamp conductor ends mechanically, permitting tightening without specialised crimping tools. Design allows straightforward swapping of worn connectors using basic hand tools or none at all.

Repair or adapt wiring rapidly on the bench or in a vehicle, cutting downtime during installations.

Space-conscious Fit – with a compact 4.6 x 2 cm footprint

Small dimensions keep the connector profile low, enabling placement in restricted enclosures and behind panels. The compact form keeps adjacent wiring manageable.

Useful where space is limited, such as behind car stereo units or inside tight amplifier racks.
