Universal 5/16" Ring Terminal Adapter

The Stinger SPT55301 Battery Terminal Adapter fits any 5/16" ring terminal and works on both positive and negative battery posts. It provides a single 4-gauge and a single 8-gauge output for flexible power distribution in car audio and accessory installations. The Shoc-Chrome finish resists corrosion for a durable, high-power connection.

Dual-Gauge Output Capacity

One 4-gauge and one 8-gauge output handle main amplifier feeds and smaller accessory wires from a single terminal. The adapter runs out of headroom when a system requires more than two power leads or conductors larger than 4-gauge. It is built for standard automotive voltage and high-current draw typical of aftermarket audio upgrades.

Replaces OEM Clamp Terminals

This adapter upgrades factory clamp-style terminals that lack ring-terminal compatibility or sufficient gauge options. The jump is worth it when adding an amplifier or multiple accessories that need secure, corrosion-resistant posts. It is not for installations requiring more than two output connections or terminals smaller than 5/16".

Questions about this item

Will the 4-gauge and 8-gauge outputs on this SPT55301 adapter fit the ring terminals I already have on my older amplifier wiring?

Yes, the adapter accepts any 5/16" ring terminal, so your existing 4-gauge and 8-gauge power leads will bolt straight onto the single outputs provided.

How can I verify the Shoc-Chrome terminal adapter is making a solid high-power connection once installed?

After tightening the 5/16" ring terminals onto the single 4-gauge and 8-gauge outputs, check that the adapter sits flush on the battery post with no movement and that the Shoc-Chrome finish shows clean metal contact all round.

Does the STINGER SPT55301 package include the 5/16" ring terminals or battery bolts, or do I need to buy those separately?

The adapter itself is supplied only; you must provide your own 5/16" ring terminals for the 4-gauge and 8-gauge cables and the correct battery post bolts for your vehicle.
