Rockford Fosgate 100 A ANL Fuse
The Rockford Fosgate RFFA100 is a 100 A ANL fuse designed for automotive audio power circuits. It protects amplifiers and wiring from over-current damage. Installers working on high-output systems use this fuse at the battery connection. The platinum construction resists corrosion in engine-bay environments.
Capacity and headroom
Rated at 100 A, the fuse carries continuous current up to that level before opening. It handles the draw of large mono-block or multi-channel amplifiers with headroom for musical peaks. The fuse runs out when sustained current exceeds the rating, interrupting the circuit to prevent wire melting or component failure. Weight is 1.10.
Upgrade context
This fuse replaces a blown ANL fuse of the same rating or upgrades from a lower-amperage ANL fuse when amplifier power is increased. The jump is worth it when the new amplifier's current draw approaches or exceeds the old fuse rating. First listed by the manufacturer in 2021, it fits standard ANL fuse holders already present in many installations.

Questions about this item
Will the 100 A ANL fuse protect my existing amplifier wiring?
The 100 A ANL fuse is designed to protect power cables rated for up to 100 amperes, matching the fuse rating to the wire capacity in your current installation.
How can I verify the fuse is intact after installing it in the holder?
Inspect the transparent window on the fuse body; an unbroken metal strip visible through the window confirms the 100 A ANL fuse is functional.
Does the package include a fuse holder or only the 100 A ANL fuse itself?
The box contains one 100 A ANL fuse weighing 1.10 units; a compatible ANL fuse holder must be purchased separately.
