Let's Power Up!

NVX is proud to introduce the XFDBU2 Two Position Fused Distribution Block. This is the perfect solution for multiple amp wiring. This allows you to run one power wire from your battery to 2 fused power outs with the option of different amperage fuses.

As with all NVX products, you can can expect truly great design and engineering. The XFDBU2 is made of solid brass and satin chrome plated for the best power transfer possible.

General Features

  • 2-Position Mini-ANL Fuse Holder
  • One 1/0 gauge or 4 gauge Input
  • Two 4 gauge or 8 gauge Outputs
  • Made of Solid brass and satin chrome plated for the best power transfer possible
  • High temperature polycarbonate base and cover
  • No-fail termination and current flow
  • Authorized Internet Dealer
  • 1-year Manufacturer's warranty

Frequently Asked Questions (FAQ)


The XFDBU2 uses MANL (Mini-ANL) fuses. These are preferred over glass AGU fuses because they offer a bolt-down style connection that handles high vibration and heat without losing tension or causing "nuisance" blown fuses.
It features one 1/0 or 4 AWG input and two 4 or 8 AWG outputs. Use the included sizing inserts to ensure a tight fit. For 1/0 AWG inputs, remove the insert; for 8 AWG outputs, keep the insert in for a secure "crush" connection.
Check the set screws holding the fuse in place. If they are loose, current can't jump the gap. Tighten both sides of the fuse holder with an Allen key. If it's still dead, use a multimeter to check for 12V on both sides of the fuse.
Not necessarily. For grounds, use the non-fused XDBU series. Fuses are only needed on the Positive (+) side to prevent fires in the event of a power wire shorting against the vehicle's metal chassis.
Yes, the high-impact polycarbonate cover is designed to handle engine bay temperatures. However, always mount the block as far from the exhaust manifold as possible and ensure the cover is snapped on to prevent accidental tool shorts.

Perfect dist block.

Like others mentioned its a solid product, Using it on 4 gauge power wire. The cover snaps back on tight & not loose like other distribution block covers. Another great product from NVX.

Simple and easy distribution/fuse block

Very simple install, appears to be a quality piece of equipment. Comes with adapters for 4/8 GA wire as well (can have 0/1 or 4 GA input with 4 GA or 8GA output. One size allen key to adjust everything. Looks nice. No complaints.

Solid distribution block

Top quality, solid 2 fuse holder / distribution block. The cover snaps on without concern but be careful when aligning the tabs

Another great NVX product

I bought this distribution block when I bought the rest of my set-up from Sonic. The construction is very well and is definitely not cheap feeling. The one I received had a broken tab on the top, and without hesitation they sent me a brand new one free of charge. Nvx makes excellent products and the xfdbu2 is a superb accessory.

Good quality

The product is exactly what I needed. I have a 1/0 power source and my amp needs a 4 gauge power cable. This allows me to add another amp on the future when I'm ready. Love it!!!!

Safety

Works perfect, installed this between my two amplifiers and it looks clean. Mounts well on MDF.

Prefect size

Item is recommended for its tiny footprint and durability. Prefect for a two amp system.

Excellent Fuse Holder

I have gone through several fuse holders in numerous different installs, and the products by NVX always exceed my expectations. This fuse holder is built from quality materials and is not flimsy at all. The cover does not become brittle in colder weather (about 10 degrees F) which is normally a problem with others. It is also impervious to gas and oil which makes it a great fit under the hood and next to the battery. While the white label paint on the top disappears easily with chemicals, it does not seem to affect the plastic. The Allen set screws for the cables and well tapped and are very hard to over tighten or strip; the same also applies to the screws for the fuse itself. I would highly recommend this and other NVX products. They have yet to let me down!
