Rockford Fosgate RFTS4 4 AWG Seamed Crimp Style Ring Terminal
4 AWG Seamed Crimp Ring Terminal HPP Platinum Finish, Flexible Insulator, Superior Corrosion Resistance. 4-Pack.
Product Overview
The Rockford Fosgate RFTS4 is a 4 AWG seamed crimp style ring terminal with platinum HPP (High Performance Plating) finish for superior corrosion resistance supplied as a 4-pack. The seamed barrel design allows the terminal to be crimped onto 4 AWG wire using a standard crimping tool; the flexible insulator provides strain relief and insulation at the crimp point. Suitable for 4 AWG power, ground, and speaker wire connections at amplifier terminals, chassis ground points, and distribution blocks.
Key Specifications
- Part number: RFTS4
- Wire gauge: 4 AWG
- Terminal type: Seamed crimp style ring
- Plating: HPP (High Performance Plating) — platinum finish ✓
- Corrosion resistance: Superior (HPP plating confirmed) ✓
- Insulator: Flexible ✓
- Pack quantity: 4 terminals ✓
- Ring stud size: Not specified — confirm with Rockford Fosgate
- Overall dimensions: Not specified — confirm with Rockford Fosgate
- Maximum current rating: Not specified — confirm with Rockford Fosgate
- Weight: Not specified
Features & Benefits
- HPP Plating — Superior Corrosion Resistance — HPP (High Performance Plating) provides a platinum-finish conductive coating that resists the oxidation and corrosion that degrade bare copper terminals over time — particularly important for terminals installed in vehicle environments with heat, moisture, and vibration.
- Seamed Crimp Design — The seamed barrel is formed from flat stock with a seam along the length, allowing the barrel walls to compress more uniformly around the wire when crimped. Produces a reliable, low-resistance mechanical connection with a standard ratcheting crimp tool.
- 4 AWG Compatibility — Sized for 4 AWG wire — a commonly used gauge for amplifier power and ground connections on car audio systems rated in the 250–750W RMS range, and for secondary distribution runs from a main 1/0 AWG system.
- Flexible Insulator — The flexible insulator at the barrel entry provides strain relief, preventing the wire from flexing directly at the crimp point and reducing the risk of fatigue fracture under vehicle vibration.
- 4-Pack — Four terminals per purchase — sufficient for both ends of a two-conductor installation (power and ground at both the amplifier and source end, or two full runs).

Frequently Asked Questions
What is HPP plating?
HPP (High Performance Plating) is Rockford Fosgate's designation for their high-grade conductive terminal plating — applied to resist the oxidation and corrosion that affect bare copper connections. The platinum finish provides both the corrosion resistance and the low-contact-resistance connection required for audio-grade wiring terminals.
What is a seamed crimp terminal?
A seamed crimp terminal has a barrel formed from flat stock with a seam along its length. When crimped, the barrel deforms around the wire conductors for a mechanical and electrical connection. Seamed designs are standard in automotive wiring applications — a quality ratcheting crimp tool produces a reliable, low-resistance joint.
What stud size does the RFTS4 ring fit?
Ring hole diameter (stud size) is not confirmed in the supplier data. Confirm from the official Rockford Fosgate RFTS4 product page before purchasing. Common sizes are 5/16" and 3/8".
How many terminals are in a pack?
Four terminals per pack.
What wire gauge does this terminal suit?
4 AWG. Do not use with larger gauge wire (e.g. 2 AWG or 1/0 AWG) — the barrel will not crimp correctly around undersized wire.
