Questions & Answers
We recommend using it for 4 AWG &amp 6 AWG This is an 8 AWG cable. As a result, it shouldn't be an issue since 6 AWG is right in the middle. The battery connection side should be connected to the amp, while the other side should be connected to the extra power supply. It will take you just a few minutes to unscrew the end caps, insert your wires and tighten the allen bolts This item does not come with a fuse. A new AGU fuse will be needed to complete the connection. You'll need to choose one of 40, 60, 80, or 100 amps. In order to use this holder, it must be placed in the center. Here is what I hope will help.
Fuses with ratings ranging from 1 to 60 amps, sized 13/32" x 1 1/2". The AGC Fuses have a 1/20 to 30 amp rating. They measure 1/4" x 1 1/4".
An easier question to answer is whether the item is water resistant. As little water will make its way into the top of the engine bay while you drive, this shouldn't be a huge issue. The ends of the clips have rubber grommets that wrap around the wire so that the interior should be protected from the elements
The answer to the fourth question is yes. The insert can be used with gauges of either 4 or 8
Selected User Reviews For Rockford Fosgate Single In-Line AGU Fuse Holder for 4 AWG or 8 AWG Wire
When the fuses are installed, those fuses can't be screwed in as they can't be screwed in. I also have big, meaty, clumsy hands. When trying to fit the tiny fuses and screws into their box-style holders while they were mounted on my firewall, the buzz of curse words was a bit loud. As this slides out of the bracket holder, mounting is a breeze, and the fuses are easy to insert. Compared to the cheap fuseholder I got in my kit, the screw-down cap makes a far more secure and watertight seal. There's a top to that thing that seems to come off if I look at it just the wrong way. If you don't have to drop small screws into the guts of the engine bay and use a magnet to fish them out, you'll have more time to drink beer with your wife knowing you're working hard on a project. This is definitely worth the Make sure that you also order fuses to go along.

The purpose of this purchase is to use it My gauge is roughly in the middle between 4 and 8 gauge, so I guess it should work. The thing is not even designed to hold 6 gauge, much less 4 gauge, without modifying it. In order to keep water from getting into your wire sleeving, the rubber seal on the end caps must be around it. Once you have inserted it through the hole in the end cap, you must attach it to the end cap. It pretty much speaks for itself. It doesn't fit more than 6 gauge without the rubber seal due to the size of the hole on the end cap. This means that hole must be drilled out in order to counteract this. There's no problem with that if the plastic is removed but, by drilling out the seal, the rubber has less surface area to grasp. It is possible that the rubber seal will be literally pulled out of the hole if the wires are not perfectly straight or if you bump the system. Since this is only a 6 gauge version, I would never get this for a 4 gauge version. There may have been a problem with the size.

My original rating was 2 stars because I thought it would not fit 4awg wire. However, after reading the descriptions of other similar products, I realized that there is a reducer that is hard to remove. As a result, I am giving this product a 3 star rating. The majority of them are also likely to be wrong as I was initially.

The one that came with the wiring kit was replaced by this one. The program does what is expected of it. It is recommended that you use the mount that comes with it since the plastic becomes brittle over time and will tend to break (like my last one did) if it is moved When it has been breached and water gets past the seals, it is a good idea to give up. Before the fuse did its job, the last one got so hot that it melted the piece to the ground. It is still my preferred fuse holder in spite of these issues, and I highly recommend it.

The fuse holder on this device is really just a simple piece of metal. Be prepared to buy the fuse separately since the fuse is not included. It's also a really lovely fuse holder, aside from that.

In the housing unit, the cables are only able to use exact 4 gauge cables. I use steel ferrules and heat shrink on my cable ends for a professional look, which made the cables just big enough to not fit, so I was unable to.

This fuse will hold the circuit very tightly, so make sure the connections on both ends are good. You can either solder the fuse in, or a little bit of dielectric grease will work well. If using 4 gauge wire, you will need to remove the small rubber grommets from the ends, which are less resilient to weather and water, and to remove the rubber inserts from the screw hold downs to get them to work.

It is the same one I replaced when it broke. I use these as the only inline fuse holders I have ever used. They last forever and are easy to install. You can solder the ends of the wire to make it a solid installation and then slide the collars on as it will tighten better and be.
