Fuse holder NVX XMFH48 for big 3 upgrade

I had been looking for a good fuse holder for my 98 civic performing the big 3 upgrade using 4 gauge wire and on stock 70/75 amp alternator, and decided to get this holder for alternator to battery. I installed it and it worked, as well as a belva 80amp BMANL80 fuses, I used the same size fuse whats stock in the fuse box for the alternator. I used 3M double sided tape for the mount side of holder since it will be mounted on a metal surface, this will help from accidental grounding as well as holding, and used small screws . As for the cover/cap it seems to stay on but might add a zip tie to better hold it. Over all im satisfied with this product and will purchase again from sonic electronix. I recommend this item. Thanks sonic electronix. The shipping was fast. Got it within a few days. A++++

Great product

Nice quality fuse holder. I recommend this item because although price is comparable to other brands this one is small and can be mounted easily. I wanted a setup that was of quality and matched and once again NVX had all the items I needed.

Install was a breeze

This harness installed very easily in my car. Wires are easy to install and the fuses are very easily swapped. Will definitely purchase these again in the future.

Nice but fragile.

This products size and look is what drew me to it. It will fit nicely in many tight spaces. The durability of the plastic leaves something to be desired i had not even fully inserted my 4guage wire when the terminal box broke free from the plastic housing causing a tiny screw cover to go tumbling down my engine bay. I would recommend a larger/more durable fuze box if planning to install anywhere where the wires going in have to be bent shortly after leaving the box.

nice compact professional lookin fuse holder

it takes the nice fuses and isn't any bigger than it needs to be, been in the car for like 2 years now so far so good. about the same quality or better than my old kicker fuse holder but smaller so it doesn't look stupid in the engine bay. it looks great, unlike those chintzy clear plastic glass fuse holders.
