Overview – FH / KNI Inline fuse holders provide fuse options ranging from 30A up to 450A. The FH series inline fuse holders utilize set screws to attach to the power wire while the KNI-11 is part of our KonFUSED series that terminates with a compression fitting at each end.

Notes – When installing the FH-20, insert the power wire through each end cap before securing the fuse holder's connectors onto the wire. This is required to properly reassemble the holder in the vehicle.

Why do I need an inline fuse holder?
The job of an inline fuse holder is to protect your vehicle in case of an accident. Should the car audio system's main power wire have a short to ground, the fuse will blow and prevent additional damage from occurring.
How far from the battery should I mount an inline fuse holder?
Typically you want to mount the inline fuse holder as close to the battery as possible. General rule of thumb is 1-2 feet.
What size ANL fuse should I use with my inline fuse holder?
There are two possible answers, you can select your fuse based on the maximum rated amperage capacity of your power wire OR based on the maximum current draw your audio system is capable of. The later though must also be less then the cables maximum amperage capacity.
Do I need an inline fuse holder when adding a second battery to my car?
Yes, actually you would need two inline fuse holders in a dual battery installation if Battery A is under the hood and Battery B is in the rear of the vehicle. One inline fuse holder would not be able to protect your vehicle because with a second battery, power is already on both sides of the fuse at all times. An inline fuse holder should be placed near each battery protecting the cable that is passing through the interior of the vehicle in case of an accident.
