4 Gauge Spring Loaded Chrome Binding Post (Pair)

4 Gauge Spring Loaded Chrome Binding Post (Pair)

The 4 Gauge Spring Loaded Chrome Binding Post is designed for subwoofer builders who demand clean, secure, and high-current connections. Designed specifically for cast aluminum subwoofer frames, this terminal provides a direct wiring point for serious car audio systems. Whether you’re assembling a competition sub or rebuilding a blown woofer, this binding post makes your job easier and your results more reliable.

Unlike standard terminals, this model features an oversized wire entry hole measuring 0.365″, giving you more flexibility when working with true-spec or oversized 4 gauge cable. That’s larger than our DF-401 terminal, which has a 0.29″ opening—making this version a better fit for thick, high-strand-count wire.

Instead of dealing with loose crimp terminals or undersized wire tabs, this spring-loaded post lets you insert bare 4 AWG wire directly into the terminal. Just press, insert, and release—the clamp locks down firmly, delivering a rock-solid connection that resists vibration and thermal cycling.

Additionally, the polished chrome housing looks as good as it performs. It resists corrosion, oxidation, and heat, which makes it a perfect fit for high-output systems where durability matters. Since it mounts directly to cast aluminum frames, you get strong mechanical support and a clean install every time.

For builders pushing serious power, thicker wiring is a must. This terminal ensures that current flow remains stable, especially in SPL or competition setups. Moreover, it streamlines the wiring process during recones or full custom builds, saving both time and effort.

If you’re building subwoofers that are meant to handle real power, this is the terminal you want to use. It’s fast, strong, and built to perform under pressure.
