Description
Inline ANL or Maxi Fuse Holder 1/0 AWG or 4 AWG, Custom Tooled Solid Brass, HPP Platinum Finish.
Product Overview
The Rockford Fosgate RFFANL is an inline ANL or Maxi fuse holder accepting 1/0 AWG or 4 AWG wire custom-tooled solid brass with HPP (High Performance Plating) platinum finish. Designed for the main power run from the battery to high-power amplifiers or distribution blocks, the RFFANL provides the overcurrent protection required on 1/0 AWG positive cable runs. Accepts both ANL-style and Maxi-style fuses, covering the two common high-current fuse formats used in car audio main power runs.

Features & Benefits
-
ANL and Maxi Fuse Compatibility — Accepts both ANL (blade-style, high-current) and Maxi fuses — two of the most common high-current fuse formats used on car audio main power runs. This dual compatibility reduces the risk of purchasing the wrong fuse holder format.
-
1/0 AWG or 4 AWG Wire Compatibility — Accepts either 1/0 AWG (main power run gauge) or 4 AWG wire — suitable for protecting both heavy main runs and intermediate-gauge branch cables.
-
Custom Tooled Solid Brass — Machined brass for the mechanical strength and conductivity required on high-current main power cable protection.
-
HPP Platinum Plating — Corrosion-resistant coating for long-term contact reliability at the fuse terminals.

Frequently Asked Questions
What is the difference between ANL and Maxi fuses?
ANL fuses are large blade-style fuses used in high-current car audio main runs — typically available from 80A to 300A or higher. Maxi fuses are a different blade style covering a similar amperage range. The RFFANL accepts both formats — confirm which format is more readily available for your system's required amperage from your local supplier.
What wire gauge does this fuse holder accept?
1/0 AWG and 4 AWG — confirmed in the product description. For 4 AWG or 8 AWG branch runs, use the RFFAGU (AGU-style) fuse holder instead.
How does the RFFANL differ from the RFFAGU?
The RFFANL accepts 1/0 AWG or 4 AWG wire and uses ANL or Maxi fuses — for main power runs. The RFFAGU accepts 4 AWG or 8 AWG wire and uses AGU fuses — for secondary branch runs. The RFFANL is the larger format holder, appropriate for the higher currents of a main battery-to-amplifier run.
Is this fuse holder waterproof?
"Waterproof" is not stated for the RFFANL — unlike the RFFAGU which is explicitly described as waterproof. Confirm from the official Rockford Fosgate RFFANL product page whether a waterproof rating applies.
Does the RFFANL include a fuse?
Not confirmed in the supplier data. Confirm from the official product page.
