It had pretty good reviews and the one that I had a shop install with my amp power wire melted, I trust Crutchfield and know if I don't like the performance they'll help me find a good one, and you cant beat $10 to get my subwoofers powered up again [ Zacharias  Aug 27, 2016 ]

Do I need to buy a separate fuse or is this all I need?
[ Mike  Jan 01, 2020 ]
4 answers
Fuse is not included
[ Alec  Jan 02, 2020 ]
If I'm not mistaken the fuse did not come with it
[ John  Jan 01, 2020 ]
You Will need to purchase the AGU fuse also
[ Scott  Jan 01, 2020 ]
Does not come with fuse can get fuse at auto parts stores
[ Curtis  Jan 01, 2020 ]
Could 10 gauge wire be use with this holder?
[ Levi  Dec 07, 2014 ]
6 answers
Yes although 10 gauge is very small upgrading to a bigger wire would be better for your amp and everything involved... I have 4 gauge wire hooked for mine...
[ SCOTT  Dec 08, 2014 ]
It should work ok, 10 guage is actually smaller in diameter than 4 and 8 guage. 4 & 8 are specified to work.
[ NED R  Dec 08, 2014 ]
The Fuse Holder in question is designed to handle either 4 or 8 gauge wire. 10 gauge wire is smaller in diameter than 8 gauge so unfortunately the answer is no . I would recommend that you use the 4 gauge wire . You will have less voltage drop in the length of wire used. although it is more expensive you will get more of the voltage your amp needs to run at full (14.4 Volt ) power .
[ STEPHEN  Dec 08, 2014 ]
[ TERRY  Dec 08, 2014 ]
Yes but it won't be sealed as good
[ JERAMIE  Dec 08, 2014 ]
Yes. 10 gauge size can be used.
[ EDWARD G  Dec 08, 2014 ]
How does the fuse snap in? Are there screws on both ends? Do they have to be loosened for the fuse to slide in snugly or are they locking screws?
[ Michael  Mar 01, 2014 ]

Both plastic end caps are unscrewed to allow access then when the fuse is in place secure both end caps back in place to secure fuse in place hope this answered your question .
[ KERTTON  Mar 05, 2014 ]
the screws on the ends are just to hold your power wire in place. once the end caps are off the fuse just firmly press the fuse in one end and put it back together and the fuse will be held in place
[ JASON C  Mar 02, 2014 ]
Both ends of the fuse holder unscrew off and the fuse is held in when u tighten it back together I have one with a 60 amp fuse works great never had an issue.
[ SCOTT  Mar 02, 2014 ]
First you must unscrew the fuse holder ends from the middle. They are plastic so be careful , there . Next unscrew the set screws that will hold the wires tight. Remove one metal end. Place the fuse in the middle section of the fuse holder. Replace the metal end , and then with the wire cut and stripped place the plastic fuse holder ends over the wire with the threaded sides facing the middle piece of the fuse holder. Put the stripped wire ends into the fuse holder metal ends and replace and tighten the set screws. Then screw the plastic end pieces of the fuse holder on to the middle piece. This is what I did. Remember when mounting the fuse holder, it goes between the battery and the amp. It is also plastic so do not over tighten the mounting screws so they will not crack the fuse holder. I hope this was helpful . It seems I used a lot of words for a simple task so don't be put off by this. If you can change the batteries in a flashlight you can do this too.
[ STEPHEN  Mar 02, 2014 ]
Both ends of the fuse holder unscrew.(its the clear plastic piece) Then the fuse slides into the cylinder tube. Then you screw or spin the ends back on.
[ JASON  Mar 02, 2014 ]
the fuse block has a round fuse and has compression fittings on each side of the fuse. no tools to change fuse. good fuse block easier to see use in person
[ ELIZABETH E  Mar 02, 2014 ]
Screws hold the wire in on both sides where the fuse fits snugly in between
[ JORDAN  Mar 02, 2014 ]
Those holes on the side is just to mount it somewhere and the fuse just slides in
[ VINCENT C  Mar 02, 2014 ]
