Fuses protect your car audio system and vehicle from damage from high current. Connect the fuse holder within 12” of the battery to protect your battery, audio system, and vehicle.
These car audio fuse holders are also included with our amplifier wiring kits. If you plan to add an in-line fuse to multiple wires, you can use separate fuses in a modular “block” configuration (as pictured above).
The 100 amp 4 AWG ANL fuse block accepts 4 AWG power or ground wire. The 250 amp, 1/0 AWG fuse block accepts 1/0 AWG power or ground wire. Set-screw terminals secure the wires firmly in place.
If you blow a fuse, first try to figure out what caused it. Once you correct the issue, you can replace the ANL fuse, available from many suppliers.
